1TDMK/TM collection synchronous motors (such as TDMK collection brushed synchronous motors and TMW sequence brushless synchronous motors) are broadly utilised in mining, cement and other industries. It is mostly employed to drive mechanical products with decrease velocity and greater electricity, and the major transmission grid variety ball mill, rod mill, and coal mill. This sequence of motors adopts new technologies, new materials, new processes, beautiful materials assortment, and sophisticated production. It has the traits of modest dimension, light-weight weight, early visual appeal, substantial effectiveness, low sounds, minimal vibration, protected and reputable procedure, and convenient and risk-free use and maintenance. .
This series of synchronous motors are divided into two types: shaft drilling motors and shaft non-piercing motors. The shaft punching motor need to be utilised with a pneumatic clutch (the pneumatic clutch wants to be prepared by the person), and the shaft not punching motor demands a greater beginning functionality (remember to specify when purchasing)
Electrical power variety: 200KW~12000KW, rated voltage: 3000, 6000, 10000V, rated velocity: one hundred fifty, 167, 187.five, 200r/min etc., protection level: IP00IP20IP23IP44IP54 Doing work method: S1, cooling method :IC01IC37IC81W
Set up method: IM7311IM7312IM7321 And many others
TDMK series shaft-punching synchronous motors, whose commencing strategy is utilised with pneumatic clutch, can comprehend the segmented starting of synchronous motor and mill load, with little effect on the user’s electricity grid, and permitting complete voltage immediate beginning.
TDMK series shafts are not perforated synchronous motors with extremely higher beginning performance, which can satisfy the requirements of consumers to start directly with load.
TDMK collection synchronous motors have higher running steadiness and strong overload capability. When the grid voltage drops or the motor is overloaded, the excitation method can immediately modify and implement sturdy excitation to ensure the security of the motor.
The security device is advanced and complete. Stator windings and bearings are outfitted with temperature detection gadgets, which can monitor, alarm and trip.
TMW collection brushless synchronous motors, its brushless excitation system adopts a rotating rectifier, a rotating armature AC major excitation machine, and a coaxial built-in construction with the synchronous motor. It has automated de-excitation security and automated excitation at the best time of polarity. The smart computerized manage perform of load out-of-phase re-stepping and out-of-step safety has a higher diploma of stability and quick reaction performance, and the electricity provide program voltage transiently fluctuates and brings about oscillation or the driven mechanical tools and procedure flow look When the transient disturbance is powerful, the motor has the perform of computerized clever security and handle, which has a significantly smaller sized effect on the operation of the motor than the traditional brushed synchronous motor.
four. Construction kind
The motor is composed of two pedestal bearings, stator, rotor and base plate.
The shaft drilling motor has a deep hole (intake hole) at the center of the tail of the shaft, and an air gap at the shaft extension conclude for putting in a pneumatic clutch. The shaft of TMW series brushless synchronous motors is outfitted with a coaxial rotating rectifier and rotating armature AC main exciter, which replaces the collector ring and brush composition of TDMK sequence motors to supply excitation for the motor.
Stator: The stator body is welded by steel plate, and the motor stator outlet is led by large-voltage rubber cable. The outlet wire can be led out from the base portion or from the principal junction box on the electrical aspect.
The stator core is laminated with low-decline silicon steel sheets, and the main sections are divided by radial air flow ducts.
The stator winding is F grade insulation, and the temperature increase is assessed in accordance to B quality to help lengthen the provider life. Making use of VPI all round dipping paint treatment, it has higher electrical functionality, mechanical strength, bonding functionality, moisture resistance and thermal stability.
The rotor magnetic pole core is made of laminated steel plates, and the magnetic pole coils are insulated with class F.
When the user adopts the pneumatic clutch, the shaft can be punched according to the user’s specifications. The rotor support is manufactured of cast steel.
TDMK series brushed synchronous motors are geared up with steel slip rings on the shaft. An AC exciter and a rotating rectifier plate are mounted on the shaft of the TMW series brushless synchronous motor. The bottom plate is a steel plate welded construction, which is welded with a 20-30mm metal plate.
Adopt seat variety spherical sliding bearing. The bearings are insulated to avert shaft currents. Use new lubricating oil and slender-walled bearing alloy bushes, and set electromagnetic centerline indicators.
TMW series brushless synchronous motors have tiny rotary rectifier discs, compact buildings and electrical connections. The fixed areas and the warmth sink are built-in, which is dependable in operation, reduced in failure price, and practical in set up and maintenance.
