1TDMK/TM series synchronous motors (including TDMK sequence brushed synchronous motors and TMW series brushless synchronous motors) are widely employed in mining, cement and other industries. It is mostly utilised to generate mechanical gear with reduce pace and greater energy, and the major transmission grid variety ball mill, rod mill, and coal mill. This series of motors adopts new technology, new components, new processes, beautiful materials variety, and sophisticated producing. It has the traits of little size, light-weight fat, early appearance, substantial performance, low sounds, low vibration, risk-free and trustworthy procedure, and handy and protected use and upkeep. .

This sequence of synchronous motors are divided into two varieties: shaft drilling motors and shaft non-piercing motors. The shaft punching motor must be utilised with a pneumatic clutch (the pneumatic clutch requirements to be well prepared by the consumer), and the shaft not punching motor demands a increased starting up overall performance (make sure you specify when purchasing)

3CZPT attributes
TDMK series shaft-punching synchronous motors, whose beginning method is employed with pneumatic clutch, can understand the segmented commencing of synchronous motor and mill load, with tiny impact on the user’s energy grid, and making it possible for total voltage immediate starting up.
TDMK collection shafts are not perforated synchronous motors with quite higher beginning efficiency, which can fulfill the needs of customers to start off immediately with load.
TDMK collection synchronous motors have large working security and robust overload potential. When the grid voltage drops or the motor is overloaded, the excitation technique can automatically adjust and implement strong excitation to guarantee the security of the motor.
The security gadget is advanced and complete. Stator windings and bearings are outfitted with temperature detection gadgets, which can keep an eye on, alarm and trip.
TMW series brushless synchronous motors, its brushless excitation program adopts a rotating rectifier, a rotating armature AC main excitation device, and a coaxial integrated structure with the synchronous motor. It has computerized de-excitation protection and computerized excitation at the greatest time of polarity. The clever automated manage function of load out-of-stage re-stepping and out-of-phase safety has a substantial diploma of balance and quick reaction performance, and the energy provide technique voltage transiently fluctuates and causes oscillation or the pushed mechanical products and method stream look When the transient disturbance is powerful, the motor has the perform of computerized intelligent safety and handle, which has a considerably smaller effect on the operation of the motor than the standard brushed synchronous motor.

four. Composition type
The motor is composed of two pedestal bearings, stator, rotor and bottom plate.
The shaft drilling motor has a deep hole (intake gap) at the centre of the tail of the shaft, and an air gap at the shaft extension end for installing a pneumatic clutch. The shaft of TMW series brushless synchronous motors is outfitted with a coaxial rotating rectifier and rotating armature AC primary exciter, which replaces the collector ring and brush framework of TDMK series motors to provide excitation for the motor.
Stator: The stator frame is welded by steel plate, and the motor stator outlet is led by high-voltage rubber cable. The outlet wire can be led out from the base part or from the major junction box on the electrical facet.

The stator core is laminated with lower-reduction silicon steel sheets, and the main sections are divided by radial ventilation ducts.
The stator winding is F grade insulation, and the temperature rise is assessed according to B grade to support increase the service daily life. Using VPI overall dipping paint remedy, it has large electrical functionality, mechanical energy, bonding efficiency, dampness resistance and thermal balance.
The rotor magnetic pole main is manufactured of laminated steel plates, and the magnetic pole coils are insulated with course F.
When the consumer adopts the pneumatic clutch, the shaft can be punched according to the user’s requirements. The rotor support is produced of forged 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 set up on the shaft of the TMW collection brushless synchronous motor. The base plate is a metal plate welded framework, which is welded with a 20-30mm metal plate.

Undertake 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 indications.
TMW series brushless synchronous motors have small rotary rectifier discs, compact structures and electrical connections. The fastened elements and the warmth sink are built-in, which is dependable in procedure, lower in failure fee, and hassle-free in set up and upkeep.
