1TDMK/TM sequence synchronous motors (which includes TDMK sequence brushed synchronous motors and TMW collection brushless synchronous motors) are widely utilised in mining, cement and other industries. It is primarily used to push mechanical products with reduced speed and higher electrical power, and the primary transmission grid variety ball mill, rod mill, and coal mill. This series of motors adopts new technological innovation, new resources, new processes, beautiful content variety, and innovative producing. It has the characteristics of tiny dimension, gentle excess weight, early visual appeal, substantial efficiency, lower sounds, reduced vibration, secure and dependable operation, and convenient and safe use and maintenance. .
This series of synchronous motors are divided into two varieties: shaft drilling motors and shaft non-piercing motors. The shaft punching motor must be utilized with a pneumatic clutch (the pneumatic clutch demands to be ready by the user), and the shaft not punching motor wants a larger commencing performance (make sure you specify when buying)

3CZPT qualities
TDMK sequence shaft-punching synchronous motors, whose beginning technique is utilized with pneumatic clutch, can realize the segmented commencing of synchronous motor and mill load, with small effect on the user’s power grid, and enabling entire voltage immediate commencing.
TDMK sequence shafts are not perforated synchronous motors with very higher starting up efficiency, which can meet up with the wants of end users to begin immediately with load.
TDMK collection synchronous motors have large working steadiness and robust overload ability. When the grid voltage drops or the motor is overloaded, the excitation method can routinely change and employ strong excitation to make certain the stability of the motor.
The security device is superior and full. Stator windings and bearings are equipped 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 main excitation equipment, and a coaxial built-in framework with the synchronous motor. It has computerized de-excitation safety and computerized excitation at the very best time of polarity. The clever automatic control perform of load out-of-step re-stepping and out-of-stage security has a higher degree of steadiness and fast response overall performance, and the electrical power offer system voltage transiently fluctuates and causes oscillation or the driven mechanical tools and approach circulation seem When the transient disturbance is sturdy, the motor has the operate of automatic intelligent security and control, which has a significantly smaller impact on the procedure of the motor than the conventional brushed synchronous motor.
four. Construction kind
The motor is composed of two pedestal bearings, stator, rotor and bottom plate.
The shaft drilling motor has a deep gap (ingestion hole) at the center of the tail of the shaft, and an air gap at the shaft extension end for installing a pneumatic clutch. The shaft of TMW sequence 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 provide excitation for the motor.
Stator: The stator body is welded by steel plate, and the motor stator outlet is led by higher-voltage rubber cable. The outlet wire can be led out from the base part or from the main junction box on the electrical aspect.
The stator main is laminated with reduced-loss silicon steel sheets, and the main sections are separated by radial ventilation ducts.
The stator winding is F grade insulation, and the temperature rise is assessed according to B grade to help increase the support existence. Utilizing VPI general dipping paint treatment, it has substantial electrical overall performance, mechanical energy, bonding performance, dampness resistance and thermal stability.
The rotor magnetic pole main is manufactured of laminated metal plates, and the magnetic pole coils are insulated with class F.
When the person adopts the pneumatic clutch, the shaft can be punched in accordance to the user’s specifications. The rotor support is created 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 installed on the shaft of the TMW series brushless synchronous motor. The bottom plate is a metal plate welded composition, which is welded with a twenty-30mm steel plate.
Adopt seat variety spherical sliding bearing. The bearings are insulated to avoid shaft currents. Use new lubricating oil and skinny-walled bearing alloy bushes, and established electromagnetic centerline indicators.
TMW series brushless synchronous motors have small rotary rectifier discs, compact constructions and electrical connections. The set elements and the warmth sink are integrated, which is trustworthy in procedure, reduced in failure price, and practical in installation and servicing.
