How to Select a Gear Motor

A gearmotor is an electrical machine that transfers energy from one place to another. There are many types of gearmotors. This article will discuss the types of gearmotors, including Angular geared motors, Planetary gearboxes, Hydraulic gear motors, and Croise motors. In addition to its uses, gearmotors have many different characteristics. In addition, each type has distinct advantages and disadvantages. Listed below are a few tips on selecting a gearmotor.

Angular geared motors

Angular geared motors are the optimum drive element for applications where torques, forces, and motions need to be transferred at an angle. Compared to other types of geared motors, these have few moving parts, a compact design, and a long life. Angular geared motors are also highly efficient in travel drive applications. In addition to their durability, they have a low maintenance requirement and are highly corrosion-resistant.
Helical worm geared motors are a low-cost solution for drives that employ angular geared motors. They combine a worm gear stage and helical input stage to offer higher efficiency than pure worm geared motors. This drive solution is highly reliable and noise-free. Angular geared motors are often used in applications where noise is an issue, and helical worm geared motors are particularly quiet.
The gear ratio of an angular geared motor depends on the ratio between its input and output shaft. A high-quality helical geared motor has a relatively low mechanical noise level, and can be installed in almost any space. The torque of a helical geared motor can be measured by using frequency measurement equipment. The energy efficiency of angular geared motors is one of the most important factors when choosing a motor. Its symmetrical arrangement also allows it to operate in low-speed environments.
When selecting the right angular geared motor, it is important to keep in mind that increased torque will lead to poor output performance. Once a gear motor reaches its stall torque, it will no longer function properly. This makes it important to consult a performance curve to choose the appropriate motor. Most DC motor manufacturers are more than happy to provide these to customers upon request. Angular geared motors are more expensive than conventional worm gear motors.

Planetary gearboxes

Planetary gearboxes are used in industrial machinery to generate higher torque and power density. There are three main types of planetary gearboxes: double stage, triple stage, and multistage. The central sun gear transfers torque to a group of planetary gears, while the outer ring and spindle provide drive to the motor. The design of planetary gearboxes delivers up to 97% of the power input.
The compact size of planetary gears results in excellent heat dissipation. In some applications, lubrication is necessary to improve durability. Nevertheless, if you are looking for high speed transmission, you should consider the additional features, such as low noise, corrosion resistance, and construction. Some constructors are better than others. Some are quick to respond, while others are unable to ship their products in a timely fashion.
The main benefit of a planetary gearbox is its compact design. Its lightweight design makes it easy to install, and the efficiency of planetary gearboxes is up to 0.98%. Another benefit of planetary gearboxes is their high torque capacity. These gearboxes are also able to work in applications with limited space. Most modern automatic transmissions in the automotive industry use planetary gears.
In addition to being low in cost, planetary gearboxes are a great choice for many applications. Neugart offers both compact and right angle versions. The right angle design offers a high power-to-weight ratio, making it ideal for applications where torque is needed to be transmitted in reverse mode. So if you’re looking for an efficient way to move heavy machinery around, planetary gearboxes can be a great choice.
Another advantage of planetary gearboxes is their ability to be easily and rapidly changed from one application to another. Since planetary gears are designed to be flexible, you don’t have to buy new ones if you need to change gear ratios. You can also use planetary gears in different industries and save on safety stock by sharing common parts. These gears are able to withstand high shock loads and demanding conditions.
Motor

Hydraulic gear motors

Hydraulic gear motors are driven by oil that is pumped into a gear box and causes the gears to rotate. This method of energy production is quiet and inexpensive. The main drawbacks of hydraulic gear motors are that they are noisy and inefficient at low speeds. The other two types of hydraulic motors are piston and vane-type hydraulic motors. The following are some common benefits of hydraulic gear motors.
A hydraulic gear motor is composed of two gears – a driven gear and an idler. The driven gear is attached to the output shaft via a key. High-pressure oil flows into the housing between the gear tips and the motor housing, and the oil then exits through an outlet port. Unlike a conventional gear motor, the gears mesh to prevent the oil from flowing backward. As a result, they are an excellent choice for agricultural and industrial applications.
The most common hydraulic gear motors feature a gerotor and a drive gear. These gears mesh with a larger gear to produce rotation. There are also three basic variations of gear motors: roller-gerotor, gerotor, and differential. The latter produces higher torque and less friction than the previous two. These differences make it difficult to choose which type is the best for your needs. A high-performance gear motor will last longer than an ordinary one.
Radial piston hydraulic motors operate in the opposite direction to the reciprocating shaft of an electric gearmotor. They have nine pistons arranged around a common center line. Fluid pressure causes the pistons to reciprocate, and when they are stationary, the pistons push the fluid out and move back in. Because of the high pressure created by the fluid, they can rotate at speeds up to 25,000RPM. In addition, hydraulic gear motors are highly efficient, allowing them to be used in a wide range of industrial and commercial applications.
Hydraulic gear motors complement hydraulic pumps and motors. They are also available in reversible models. To choose the right hydraulic motor for your project, take time to gather all the necessary information about the installation process. Some types require specialized expertise or complicated installation. Also, there are some differences between closed and open-loop hydraulic motors. Make sure to discuss the options with a professional before you make a decision.
Motor

Croise motors

There are many advantages to choosing a Croise gear motor. It is highly compact, with less weight and space than standard motors. Its right-angle shaft and worm gear provide smooth, quiet operation. A silent-type brake ensures no metallic sound during operation. It also offers excellent positioning accuracy and shock resistance. This is why this motor is ideal for high-frequency applications. Let’s take a closer look.
A properly matched gearmotor will provide maximum torque output in a specified period. Its maximum developing torque is typically the rated output torque. A one-twelfth-horsepower (1/8 horsepower) motor can meet torque requirements of six inch-pounds, without exceeding its breakdown rating. This lower-cost unit allows for production variations and allows the customer to use a less powerful motor. Croise gear motors are available in a variety of styles.

What Is a Gear Motor?

A gear motor is an electric motor coupled with a gear train. It uses either DC or AC power to achieve its purpose. The primary benefit of a gear reducer is its ability to multiply torque while maintaining a compact size. The trade-off of this additional torque comes in the form of a reduced output shaft speed and overall efficiency. However, proper gear technology and ratios provide optimum output and speed profiles. This type of motor unlocks the full potential of OEM equipment.

Inertial load

Inertial load on a gear motor is the amount of force a rotating device produces due to its inverse square relationship with its inertia. The greater the inertia, the less torque can be produced by the gear motor. However, if the inertia is too high, it can cause problems with positioning, settling time, and controlling torque and velocity. Gear ratios should be selected for optimal power transfer.
The duration of acceleration and braking time of a gear motor depends on the type of driven load. An inertia load requires longer acceleration time whereas a friction load requires breakaway torque to start the load and maintain it at its desired speed. Too short a time period can cause excessive gear loading and may result in damaged gears. A safe approach is to disconnect the load when power is disconnected to prevent inertia from driving back through the output shaft.
Inertia is a fundamental concept in the design of motors and drive systems. The ratio of mass and inertia of a load to a motor determines how well the motor can control its speed during acceleration or deceleration. The mass moment of inertia, also called rotational inertia, is dependent on the mass, geometry, and center of mass of an object.
Motor

Applications

There are many applications of gear motors. They provide a powerful yet efficient means of speed and torque control. They can be either AC or DC, and the two most common motor types are the three-phase asynchronous and the permanent magnet synchronous servomotor. The type of motor used for a given application will determine its cost, reliability, and complexity. Gear motors are typically used in applications where high torque is required and space or power constraints are significant.
There are two types of gear motors. Depending on the ratio, each gear has an output shaft and an input shaft. Gear motors use hydraulic pressure to produce torque. The pressure builds on one side of the motor until it generates enough torque to power a rotating load. This type of motors is not recommended for applications where load reversals occur, as the holding torque will diminish with age and shaft vibration. However, it can be used for precision applications.

Size

The safety factor, or SF, of a gear motor is an important consideration when selecting one for a particular application. It compensates for the stresses placed on the gearing and enables it to run at maximum efficiency. Manufacturers provide tables detailing typical applications, with multiplication factors for duty. A gear motor with a SF of three or more is suitable for difficult applications, while a gearmotor with a SF of one or two is suitable for relatively easy applications.

Motor

Cost

A gear motor is an electric motor that is paired with a gear train. They are available in AC or DC power systems. Compared to conventional motors, gear reducers can maximize torque while maintaining compact dimensions. But the trade-off is the reduced output shaft speed and overall efficiency. However, when used correctly, a gear motor can produce optimal output and mechanical fit. To understand how a gear motor works, let’s look at two types: right-angle geared motors and inline geared motors. The first two types are usually used in automation equipment and in agricultural and medical applications. The latter type is designed for rugged applications.
In addition to its efficiency, DC gear motors are space-saving and have low energy consumption. They can be used in a number of applications including money counters and printers. Automatic window machines and curtains, glass curtain walls, and banknote vending machines are some of the other major applications of these motors. They can cost up to 10 horsepower, which is a lot for an industrial machine. However, these are not all-out expensive.
Electric gear motors are versatile and widely used. However, they do not work well in applications requiring high shaft speed and torque. Examples of these include conveyor drives, frozen beverage machines, and medical tools. These applications require high shaft speed, so gear motors are not ideal for these applications. However, if noise and other problems are not a concern, a motor-only solution may be the better choice. This way, you can use a single motor for multiple applications.
Motor

Maintenance

Geared motors are among the most common equipment used for drive trains. Proper maintenance can prevent damage and maximize their efficiency. A guide to gear motor maintenance is available from WEG. To prevent further damage, follow these maintenance steps:
Regularly check electrical connections. Check for loose connections and torque them to the recommended values. Also, check the contacts and relays to make sure they are not tangled or damaged. Check the environment around the gear motor to prevent dust from clogging the passageway of electric current. A proper maintenance plan will help you identify problems and extend their life. The manual will also tell you about any problems with the gearmotor. However, this is not enough – it is important to check the condition of the gearbox and its parts.
Conduct visual inspection. The purpose of visual inspection is to note any irregularities that may indicate possible problems with the gear motor. A dirty motor may be an indication of a rough environment and a lot of problems. You can also perform a smell test. If you can smell a burned odor coming from the windings, there may be an overheating problem. Overheating can cause the windings to burn and damage.
Reactive maintenance is the most common method of motor maintenance. In this type of maintenance, you only perform repairs if the motor stops working due to a malfunction. Regular inspection is necessary to avoid unexpected motor failures. By using a logbook to document motor operations, you can determine when it is time to replace the gear motor. In contrast to preventive maintenance, reactive maintenance requires no regular tests or services. However, it is recommended to perform inspections every six months.
