Three-Phase AC Synchronous Motor Driving Ball Mill, Rod Mill, AG Mill Semi-Autogenous Mill

1TDMK/TM sequence synchronous motors (like TDMK collection brushed synchronous motors and TMW series brushless synchronous motors) are commonly utilised in mining, cement and other industries. It is mostly utilised to travel mechanical products with lower speed and higher electrical power, and the major transmission grid type ball mill, rod mill, and coal mill. This series of motors adopts new engineering, new resources, new procedures, beautiful materials assortment, and innovative production. It has the attributes of little size, light fat, early visual appeal, high performance, lower sound, low vibration, safe and reputable operation, and hassle-free and risk-free use and servicing. .

This sequence of synchronous motors are divided into two types: shaft drilling motors and shaft non-piercing motors. The shaft punching motor have to be used with a pneumatic clutch (the pneumatic clutch wants to be prepared by the consumer), and the shaft not punching motor requirements a increased beginning performance (please specify when ordering)
2Basic parameters

3CZPT characteristics
TDMK collection shaft-punching synchronous motors, whose starting strategy is utilized with pneumatic clutch, can understand the segmented commencing of synchronous motor and mill load, with tiny influence on the user’s power grid, and enabling total voltage immediate starting.
TDMK sequence shafts are not perforated synchronous motors with extremely higher starting up functionality, which can meet up with the demands of consumers to start off immediately with load.
TDMK collection synchronous motors have higher operating security and powerful overload potential. When the grid voltage drops or the motor is overloaded, the excitation technique can automatically alter and apply powerful excitation to make certain the security of the motor.
The protection device is superior and full. Stator windings and bearings are equipped with temperature detection units, which can keep track of, alarm and vacation.
TMW collection brushless synchronous motors, its brushless excitation program adopts a rotating rectifier, a rotating armature AC primary excitation machine, and a coaxial built-in construction with the synchronous motor. It has automated de-excitation defense and automated excitation at the very best time of polarity. The smart automatic management purpose of load out-of-action re-stepping and out-of-step protection has a substantial degree of security and quickly reaction performance, and the power supply program voltage transiently fluctuates and leads to oscillation or the pushed mechanical products and approach circulation seem When the transient disturbance is sturdy, the motor has the operate of automated smart defense and manage, which has a considerably smaller sized effect on the operation of the motor than the classic brushed synchronous motor.

four. Structure type
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 heart of the tail of the shaft, and an air gap at the shaft extension end for putting in a pneumatic clutch. The shaft of TMW sequence brushless synchronous motors is equipped with a coaxial rotating rectifier and rotating armature AC main exciter, which replaces the collector ring and brush composition of TDMK series motors to give excitation for the motor.
Stator: The stator body 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 base part or from the primary junction box on the electrical aspect.

The stator core is laminated with minimal-decline 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 quality to assist extend the support daily life. Utilizing VPI all round dipping paint remedy, it has higher electrical functionality, mechanical strength, bonding efficiency, dampness resistance and thermal stability.
The rotor magnetic pole main is created of laminated metal 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 needs. The rotor assist is created of cast metal.
TDMK sequence brushed synchronous motors are outfitted with metal 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 20-30mm steel plate.

Undertake seat sort spherical sliding bearing. The bearings are insulated to prevent shaft currents. Use new lubricating oil and slim-walled bearing alloy bushes, and set electromagnetic centerline symptoms.
TMW series brushless synchronous motors have modest rotary rectifier discs, compact structures and electrical connections. The fastened areas and the warmth sink are integrated, which is dependable in procedure, reduced in failure fee, and hassle-free in set up and routine maintenance.
