Product Description

We,GOGOGO Mechanical&Electrical Co.,Ltd specialize in high quality energy-efficient electric motors. The combination of the best available materials, high quality sheet metal and the right amount of copper in the rotor/stator makes GOGOGO’s electric motors highly energy-efficient.

We design our electric motors to fit and match our customer’s requirements at our production site. The electric motors can be supplemented with a range of options and accessories or modified with a special design to endure any environment.
 

Electric motors account for a large part of the electricity used. If we look at the world, electric motors account for about 65 percent of the electricity used in industry. To reduce this use of electricity, there are legal requirements regarding the efficiency of electric motors manufactured in the EU, or exported into the EU.

Three-phase, single-speed asynchronous motors are covered by the requirements today. Asynchronous motors are the most common type of motor and account for 90 percent of the electricity consumption of all electric motors in the power range 0.75 – 375 kW.

According to that standard, the energy efficiency classes have the designations IE1, IE2, IE3 and IE4, where IE4 has the highest efficiency.

 

Revision of the standard

A revision of the standard was decided by the Ecodesign Committee in 2019. The revision was published on October 1, 2019. The following will apply:

For electric motors

From July 1, 2571

2-, 4-, 6- and 8-pole motors from 0.75 – 1000 kW (previously up to 375kW) are included in efficiency class IE3.

Motors within the range 0.12 – 0.75 kW must meet efficiency class IE2.

The previous possibility to replace IE3 motors with an IE2 motor with frequency drive disappears.

From July 1, 2571

For 2-, 4-, 6- and 8-pole motors from 0.12 – 1000 kW, the efficiency class IE2 now also applies to Ex eb certified motors with high safety.

Single phase motors with greater power than 0.12 kW are covered by the corresponding IE2 class.

The higher efficiency class IE4 applies to 2, 4 and 6-pole motors between 75 – 200 kW.

For frequency inverters

From July 1, 2571

For use with electric motors with power from 0.12 – 1000 kW, the frequency inverter must pass efficiency class IE2 specially designed for inverters.

Current requirements according to the Directive

Since 16 June, 2011 it is prohibited to place electric motors below energy efficiency class IE2 on the market, or to put them into service in the EU.

Since January 1, 2015, electric motors within the range 7.5 – 375 kW (2-, 4-, and 6-pole) must meet the requirements for IE3, or IE2 if the latter is combined with frequency inverters for speed control. The legal requirement thus provides 2 options.

From January 1, 2017, the requirements were tightened so that all motors 0.75 – 375 kW (2-, 4-, and 6-pole) must meet the requirements for IE3, or IE2 if they are combined with frequency inverters.

Exemptions from the current directive

  • Operation other than S1 (continuous drive) or S3 (intermittent drive) with a nominal cyclicity factor of 80 percent or lower.
  • Made for assembly with frequency inverters (integral motors).
  • Electric motors made for use in liquid.
  • Electric motors that are fully integrated into a product (e.g. a gear, pump, fan or compressor) where the energy performance is not tested independently of the product.
  • Brake motors

Electric motors intended for operation exclusively:

  • At altitudes exceeding 4 000 CHINAMFG above sea level.
  • If ambient air temperatures exceed 60°C.
  • Where maximum operating temperature exceeds 400°C.
  • Where ambient air temperatures are less than -30°C for all motors, or less than 0°C for motors with water cooling.
  • In explosive atmospheres (as defined in Directive 94/9 / EC 9)

The requirements do not apply to ships or other means of transport that carry goods or persons, since there must be specially designed engines for this purpose. (If the same mobile conveyor belt is used on ships as well as on land, the rules apply).

Also, the requirements do not apply to repair of motors previously placed on the market, or put into service – unless the repair is so extensive that the product will in practice be brand new.

If the motor is to be further exported for use outside Europe, the requirements do not apply.

Some other requirements apply to water-cooled motors

Are there specific maintenance requirements for AC motors to ensure optimal performance?

Yes, AC motors have specific maintenance requirements to ensure their optimal performance and longevity. Regular maintenance helps prevent unexpected failures, maximizes efficiency, and extends the lifespan of the motor. Here are some key maintenance practices for AC motors:

  1. Cleaning and Inspection: Regularly clean the motor to remove dust, dirt, and debris that can accumulate on the motor surfaces and hinder heat dissipation. Inspect the motor for any signs of damage, loose connections, or abnormal noise/vibration. Address any issues promptly to prevent further damage.
  2. Lubrication: Check the motor’s lubrication requirements and ensure proper lubrication of bearings, gears, and other moving parts. Insufficient or excessive lubrication can lead to increased friction, overheating, and premature wear. Follow the manufacturer’s guidelines for lubrication intervals and use the recommended lubricants.
  3. Belt and Pulley Maintenance: If the motor is coupled with a belt and pulley system, regularly inspect and adjust the tension of the belts. Improper belt tension can affect motor performance and efficiency. Replace worn-out belts and damaged pulleys as needed.
  4. Cooling System Maintenance: AC motors often have cooling systems such as fans or heat sinks to dissipate heat generated during operation. Ensure that these cooling systems are clean and functioning properly. Remove any obstructions that may impede airflow and compromise cooling efficiency.
  5. Electrical Connections: Regularly inspect the motor’s electrical connections for signs of loose or corroded terminals. Loose connections can lead to voltage drops, increased resistance, and overheating. Tighten or replace any damaged connections and ensure proper grounding.
  6. Vibration Analysis: Periodically perform vibration analysis on the motor to detect any abnormal vibrations. Excessive vibration can indicate misalignment, unbalanced rotors, or worn-out bearings. Address the underlying causes of vibration to prevent further damage and ensure smooth operation.
  7. Motor Testing: Conduct regular motor testing, such as insulation resistance testing and winding resistance measurement, to assess the motor’s electrical condition. These tests can identify insulation breakdown, winding faults, or other electrical issues that may affect motor performance and reliability.
  8. Professional Maintenance: For more complex maintenance tasks or when dealing with large industrial motors, it is advisable to involve professional technicians or motor specialists. They have the expertise and tools to perform in-depth inspections, repairs, and preventive maintenance procedures.

It’s important to note that specific maintenance requirements may vary depending on the motor type, size, and application. Always refer to the manufacturer’s guidelines and recommendations for the particular AC motor in use. By following proper maintenance practices, AC motors can operate optimally, minimize downtime, and have an extended service life.

Can you explain the difference between single-phase and three-phase AC motors?

In the realm of AC motors, there are two primary types: single-phase and three-phase motors. These motors differ in their construction, operation, and applications. Let’s explore the differences between single-phase and three-phase AC motors:

  • Number of Power Phases: The fundamental distinction between single-phase and three-phase motors lies in the number of power phases they require. Single-phase motors operate using a single alternating current (AC) power phase, while three-phase motors require three distinct AC power phases, typically referred to as phase A, phase B, and phase C.
  • Power Supply: Single-phase motors are commonly connected to standard residential or commercial single-phase power supplies. These power supplies deliver a voltage with a sinusoidal waveform, oscillating between positive and negative cycles. In contrast, three-phase motors require a dedicated three-phase power supply, typically found in industrial or commercial settings. Three-phase power supplies deliver three separate sinusoidal waveforms with a specific phase shift between them, resulting in a more balanced and efficient power delivery system.
  • Starting Mechanism: Single-phase motors often rely on auxiliary components, such as capacitors or starting windings, to initiate rotation. These components help create a rotating magnetic field necessary for motor startup. Once the motor reaches a certain speed, these auxiliary components may be disconnected or deactivated. Three-phase motors, on the other hand, typically do not require additional starting mechanisms. The three-phase power supply inherently generates a rotating magnetic field, enabling self-starting capability.
  • Power and Torque Output: Three-phase motors generally offer higher power and torque output compared to single-phase motors. The balanced nature of three-phase power supply allows for a more efficient distribution of power across the motor windings, resulting in increased performance capabilities. Three-phase motors are commonly used in applications requiring high power demands, such as industrial machinery, pumps, compressors, and heavy-duty equipment. Single-phase motors, with their lower power output, are often used in residential appliances, small commercial applications, and light-duty machinery.
  • Efficiency and Smoothness of Operation: Three-phase motors typically exhibit higher efficiency and smoother operation than single-phase motors. The balanced three-phase power supply helps reduce electrical losses and provides a more constant and uniform torque output. This results in improved motor efficiency, reduced vibration, and smoother rotation. Single-phase motors, due to their unbalanced power supply, may experience more pronounced torque variations and slightly lower efficiency.
  • Application Suitability: The choice between single-phase and three-phase motors depends on the specific application requirements. Single-phase motors are suitable for powering smaller appliances, such as fans, pumps, household appliances, and small tools. They are commonly used in residential settings where single-phase power is readily available. Three-phase motors are well-suited for industrial and commercial applications that demand higher power levels and continuous operation, including large machinery, conveyors, elevators, air conditioning systems, and industrial pumps.

It’s important to note that while single-phase and three-phase motors have distinct characteristics, there are also hybrid motor designs, such as dual-voltage motors or capacitor-start induction-run (CSIR) motors, which aim to bridge the gap between the two types and offer flexibility in certain applications.

When selecting an AC motor, it is crucial to consider the specific power requirements, available power supply, and intended application to determine whether a single-phase or three-phase motor is most suitable for the task at hand.

How does the speed control mechanism work in AC motors?

The speed control mechanism in AC motors varies depending on the type of motor. Here, we will discuss the speed control methods used in two common types of AC motors: induction motors and synchronous motors.

Speed Control in Induction Motors:

Induction motors are typically designed to operate at a constant speed determined by the frequency of the AC power supply and the number of motor poles. However, there are several methods for controlling the speed of induction motors:

  1. Varying the Frequency: By varying the frequency of the AC power supply, the speed of an induction motor can be adjusted. This method is known as variable frequency drive (VFD) control. VFDs convert the incoming AC power supply into a variable frequency and voltage output, allowing precise control of motor speed. This method is commonly used in industrial applications where speed control is crucial, such as conveyors, pumps, and fans.
  2. Changing the Number of Stator Poles: The speed of an induction motor is inversely proportional to the number of stator poles. By changing the connections of the stator windings or using a motor with a different pole configuration, the speed can be adjusted. However, this method is less commonly used and is typically employed in specialized applications.
  3. Adding External Resistance: In some cases, external resistance can be added to the rotor circuit of an induction motor to control its speed. This method, known as rotor resistance control, involves inserting resistors in series with the rotor windings. By varying the resistance, the rotor current and torque can be adjusted, resulting in speed control. However, this method is less efficient and is mainly used in specific applications where precise control is not required.

Speed Control in Synchronous Motors:

Synchronous motors offer more precise speed control compared to induction motors due to their inherent synchronous operation. The following methods are commonly used for speed control in synchronous motors:

  1. Adjusting the AC Power Frequency: Similar to induction motors, changing the frequency of the AC power supply can control the speed of synchronous motors. By adjusting the power frequency, the synchronous speed of the motor can be altered. This method is often used in applications where precise speed control is required, such as industrial machinery and processes.
  2. Using a Variable Frequency Drive: Variable frequency drives (VFDs) can also be used to control the speed of synchronous motors. By converting the incoming AC power supply into a variable frequency and voltage output, VFDs can adjust the motor speed with high accuracy and efficiency.
  3. DC Field Control: In some synchronous motors, the rotor field is supplied by a direct current (DC) source, allowing for precise control over the motor’s speed. By adjusting the DC field current, the magnetic field strength and speed of the motor can be controlled. This method is commonly used in applications that require fine-tuned speed control, such as industrial processes and high-performance machinery.

These methods provide different ways to control the speed of AC motors, allowing for flexibility and adaptability in various applications. The choice of speed control mechanism depends on factors such as the motor type, desired speed range, accuracy requirements, efficiency considerations, and cost constraints.

How to Assemble a Planetary Motor

A Planetary Motor uses multiple planetary surfaces to produce torque and rotational speed. The planetary system allows for a wide range of gear reductions. Planetary systems are particularly effective in applications where higher torques and torque density are needed. As such, they are a popular choice for electric vehicles and other applications where high-speed mobility is required. Nevertheless, there are many benefits associated with using a planetary motor. Read on to learn more about these motors.

VPLite

If you’re looking to replace the original VP, the VPLite has a similar output shaft as the original. This means that you can mix and match your original gear sets, including the input and output shafts. You can even mix metal inputs with plastic outputs. Moreover, if you decide to replace the gearbox, you can easily disassemble the entire unit and replace it with a new one without losing any output torque.
Compared to a planetary motor, a spur gear motor uses fewer gears and is therefore cheaper to produce. However, the latter isn’t suitable for high-torque applications. The torque produced by a planetary gearmotor is evenly distributed, which makes it ideal for applications that require higher torque. However, you may have to compromise on the torque output if you’re looking for a lightweight option.
The VersaPlanetary Lite gearbox replaces the aluminum ring gear with a 30% glass-filled nylon gear. This gearbox is available in two sizes, which means you can mix and match parts to get a better gear ratio. The VPLite gearbox also has a female 5mm hex output shaft. You can mix and match different gearboxes and planetary gearboxes for maximum efficiency.
Motor

VersaPlanetary

The VersaPlanetary is a highly versatile planetary motor that can be mounted in a variety of ways. Its unique design includes a removable shaft coupler system that makes it simple to swap out the motor with another. This planetary motor mounts in any position where a CIM motor mounts. Here’s how to assemble the motor. First, remove the hex output shaft from the VersaPlanetary output stage. Its single ring clip holds it in place. You can use a drill press to drill a hole into the output shaft.
After mounting the gearbox, you can then mount the motor. The mounting hardware included with the VersaPlanetary Planetary Motor comes with four 10-32 threaded holes on a two-inch bolt circle. You can use these holes to mount your VersaPlanetary on a CIM motor or a CIM-compatible motor. Once assembled, the VersaPlanetary gearbox has 72 different gear ratios.
The VersaPlanetary gearbox is interchangeable with regular planetary gearboxes. However, it does require additional parts. You can purchase a gearbox without the motor but you’ll need a pinion. The pinion attaches to the shaft of the motor. The gearbox is very sturdy and durable, so you won’t have to worry about it breaking or wearing out.

Self-centering planetary gears

A planetary motor is a simple mechanical device that rotates around a axis, with the planets moving around the shaft in a radial direction. The planets are positioned so that they mesh with both the sun gear and the output gears. The carrier 48 is flexibly connected to the drive shaft and can move depending on the forces exerted by the planet gears. In this way, the planets can always be in the optimal mesh with the output gears and sun gear.
The first step in developing a planetary gear motor is to identify the number of teeth in each planet. The number of teeth should be an integer. The tooth diameters of the planets should mesh with each other and the ring. Typically, the teeth of one planet must mesh with each other, but the spacing between them must be equal or greater than the other. This can be achieved by considering the tooth count of each planet, as well as the spacing between planets.
A second step is to align the planet gears with the output gears. In a planetary motor, self-centering planetary gears must be aligned with both input and output gears to provide maximum torque. For this to be possible, the planet gears must be connected with the output shaft and the input shaft. Similarly, the output shaft should also be able to align with the input gear.
Motor

Encoders

A planetary geared motor is a DC motor with a planetary gearbox. The motor can be used to drive heavy loads and has a ratio of 104:1. The shaft speed is 116rpm when it is unloaded. A planetary gearbox has a low backlash and is often used in applications that need high torque. Planetary Motor encoders can help you keep track of your robot’s position or speed.
They are also able to control motor position and speed with precision. Most of them feature high resolution. A 0.18-degree resolution encoder will give you a minimum of 2000 transitions per rotation between outputs A and B. The encoder is built to industrial standards and has a sturdy gearbox to avoid damage. The encoder’s robust design means it will not stall when the motor reaches its maximum speed.
There are many advantages to a planetary motor encoder. A high-quality one will not lose its position or speed even if it’s subject to shocks. A good quality planetary motor will also last a long time. Planetary motors are great for resale or for your own project. If you’re considering buying a planetary motor, consider this information. It’ll help you decide if a particular model is right for your needs.

Cost

There are several advantages of planetary motors. One of the biggest is their cost, but they can also be used in many different applications. They can be combined with a variety of gearboxes, and are ideal for various types of robots, laboratory automation, and production applications. Planetary gearboxes are available in many different materials, and plastic planetary gearboxes are an economical alternative. Plastic gearboxes reduce noise at higher speeds, and steel input stage gears are available for high torques. A modified lubrication system can help with difficult operating conditions.
In addition to being more durable, planetary motors are much more efficient. They use fewer gears, which lowers the overall cost of production. Depending on the application, a planetary motor can be used to move a heavy object, but is generally less expensive than its counterpart. It is a better choice for situations where the load is relatively low and the motor is not used frequently. If you need a very high torque output, a planetary motor may be the better option.
Planetary gear units are a good choice for applications requiring high precision, high dynamics, and high torque density. They can be designed and built using TwinCAT and TC Motion Designer, and are delivered as complete motor and gear unit assemblies. In a few simple steps, you can calculate the torque required and compare the costs of different planetary gear units. You can then choose the best model for your application. And because planetary gear units are so efficient, they are a great option for high-end industrial applications.
Motor

Applications

There are several different applications of the planetary motor. One such application is in motion control. Planetary gearboxes have many benefits, including high torque, low backlash, and torsional stiffness. They also have an extremely compact design, and can be used for a variety of applications, from rack and pinion drives to delta robotics. In many cases, they are less expensive to manufacture and use than other types of motors.
Another application for planetary gear units is in rotary tables. These machines require high precision and low backlash for their precise positioning. Planetary gears are also necessary for noise reduction, which is a common feature in rotary tables. High precision planetary gears can make the height adjustment of OP tables a breeze. And because they are extremely durable and require low noise, they are a great choice for this application. In this case, the planetary gear is matched with an AM8000 series servomotor, which gives a wide range of choices.
The planetary gear transmission is also widely used in helicopters, automobiles, and marine applications. It is more advanced than a countershaft drive, and is capable of higher torque to weight ratios. Other advantages include its compact design and reduced noise. A key concern in the development of this type of transmission is to minimize vibration. If the output of a planetary gear transmission system is loud, the vibration caused by this type of drive system may be too loud for comfort.
