1TDMK/TM sequence synchronous motors (which includes TDMK series brushed synchronous motors and TMW series brushless synchronous motors) are broadly used in mining, cement and other industries. It is largely utilized to drive mechanical equipment with reduced speed and greater power, and the main transmission grid variety ball mill, rod mill, and coal mill. This series of motors adopts new technologies, new components, new procedures, beautiful materials variety, and sophisticated producing. It has the qualities of small dimensions, light-weight fat, early look, higher performance, minimal sounds, lower vibration, secure and reputable operation, and hassle-free and risk-free use and maintenance. .
This collection of synchronous motors are divided into two types: shaft drilling motors and shaft non-piercing motors. The shaft punching motor must be employed with a pneumatic clutch (the pneumatic clutch needs to be well prepared by the consumer), and the shaft not punching motor demands a increased commencing performance (make sure you specify when ordering)

3CZPT traits
TDMK collection shaft-punching synchronous motors, whose starting up method is utilized with pneumatic clutch, can understand the segmented commencing of synchronous motor and mill load, with little influence on the user’s power grid, and making it possible for full voltage direct starting up.
TDMK collection shafts are not perforated synchronous motors with extremely large starting overall performance, which can satisfy the wants of end users to start immediately with load.
TDMK sequence synchronous motors have higher running security and strong overload ability. When the grid voltage drops or the motor is overloaded, the excitation program can instantly adjust and put into action robust excitation to ensure the security of the motor.
The defense unit is innovative and total. Stator windings and bearings are geared up with temperature detection gadgets, which can check, alarm and excursion.
TMW collection brushless synchronous motors, its brushless excitation method adopts a rotating rectifier, a rotating armature AC principal excitation device, and a coaxial built-in composition with the synchronous motor. It has automatic de-excitation defense and automated excitation at the best time of polarity. The smart automatic management perform of load out-of-stage re-stepping and out-of-step safety has a substantial degree of balance and fast reaction functionality, and the energy offer method voltage transiently fluctuates and leads to oscillation or the driven mechanical tools and method flow seem When the transient disturbance is robust, the motor has the purpose of automatic intelligent safety and control, which has a significantly more compact effect on the procedure of the motor than the traditional brushed synchronous motor.
4. Framework sort
The motor is composed of two pedestal bearings, stator, rotor and bottom plate.
The shaft drilling motor has a deep gap (intake gap) at the center of the tail of the shaft, and an air gap at the shaft extension end for setting up a pneumatic clutch. The shaft of TMW collection brushless synchronous motors is geared up with a coaxial rotating rectifier and rotating armature AC major exciter, which replaces the collector ring and brush framework of TDMK collection motors to offer excitation for the motor.
Stator: The stator frame is welded by steel plate, and the motor stator outlet is led by substantial-voltage rubber cable. The outlet wire can be led out from the foundation component or from the primary junction box on the electrical side.
The stator core is laminated with minimal-decline silicon steel sheets, and the core sections are divided by radial ventilation ducts.
The stator winding is F quality insulation, and the temperature increase is assessed in accordance to B quality to assist prolong the services lifestyle. Making use of VPI all round dipping paint remedy, it has higher electrical functionality, mechanical strength, bonding efficiency, moisture resistance and thermal steadiness.
The rotor magnetic pole core is manufactured 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 requirements. The rotor help is created of solid steel.
TDMK series brushed synchronous motors are outfitted with metal 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 metal plate welded construction, which is welded with a 20-30mm metal plate.
Adopt seat type spherical sliding bearing. The bearings are insulated to avoid shaft currents. Use new lubricating oil and slim-walled bearing alloy bushes, and set electromagnetic centerline signs.
TMW sequence brushless synchronous motors have tiny rotary rectifier discs, compact structures and electrical connections. The set parts and the warmth sink are built-in, which is dependable in procedure, low in failure charge, and hassle-free in set up and upkeep.
