1TDMK/TM sequence synchronous motors (like TDMK collection brushed synchronous motors and TMW collection brushless synchronous motors) are commonly utilized in mining, cement and other industries. It is primarily utilised to push mechanical equipment with decrease pace and higher energy, and the principal transmission grid variety ball mill, rod mill, and coal mill. This series of motors adopts new technological innovation, new resources, new processes, beautiful material assortment, and sophisticated producing. It has the characteristics of tiny size, mild bodyweight, early appearance, large efficiency, lower sounds, reduced vibration, safe and reliable procedure, and hassle-free and risk-free use and servicing. .
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 needs to be well prepared by the consumer), and the shaft not punching motor requirements a larger beginning functionality (make sure you specify when buying)

3CZPT attributes
TDMK collection shaft-punching synchronous motors, whose commencing method is employed with pneumatic clutch, can comprehend the segmented starting up of synchronous motor and mill load, with tiny influence on the user’s electricity grid, and allowing full voltage immediate starting.
TDMK sequence shafts are not perforated synchronous motors with really high commencing overall performance, which can meet the requirements of customers to start off straight with load.
TDMK collection synchronous motors have substantial operating steadiness and powerful overload ability. When the grid voltage drops or the motor is overloaded, the excitation system can automatically modify and apply sturdy excitation to make sure the balance of the motor.
The protection gadget is innovative and comprehensive. Stator windings and bearings are geared up with temperature detection products, which can check, alarm and journey.
TMW series brushless synchronous motors, its brushless excitation program adopts a rotating rectifier, a rotating armature AC main excitation equipment, and a coaxial integrated structure with the synchronous motor. It has automatic de-excitation safety and automated excitation at the greatest time of polarity. The smart automated control purpose of load out-of-stage re-stepping and out-of-phase security has a high diploma of steadiness and rapidly response efficiency, and the power offer program voltage transiently fluctuates and causes oscillation or the pushed mechanical gear and method movement show up When the transient disturbance is sturdy, the motor has the perform of computerized intelligent protection and handle, which has a significantly smaller affect on the procedure of the motor than the classic brushed synchronous motor.
4. Construction variety
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 finish for putting in a pneumatic clutch. The shaft of TMW sequence brushless synchronous motors is outfitted with a coaxial rotating rectifier and rotating armature AC primary exciter, which replaces the collector ring and brush composition of TDMK series motors to supply excitation for the motor.
Stator: The stator frame is welded by metal plate, and the motor stator outlet is led by higher-voltage rubber cable. The outlet wire can be led out from the base element or from the major junction box on the electrical aspect.
The stator core is laminated with reduced-decline silicon steel sheets, and the core sections are separated by radial ventilation ducts.
The stator winding is F grade insulation, and the temperature increase is assessed according to B grade to support extend the services life. Making use of VPI overall dipping paint remedy, it has high electrical overall performance, mechanical power, bonding overall performance, moisture resistance and thermal steadiness.
The rotor magnetic pole core is made 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 according to the user’s needs. The rotor assist is created of forged steel.
TDMK collection brushed synchronous motors are geared up with metal slip rings on the shaft. An AC exciter and a rotating rectifier plate are put in on the shaft of the TMW sequence brushless synchronous motor. The base plate is a steel plate welded construction, which is welded with a twenty-30mm steel plate.
Undertake seat kind spherical sliding bearing. The bearings are insulated to prevent shaft currents. Use new lubricating oil and slender-walled bearing alloy bushes, and set electromagnetic centerline indicators.
TMW series brushless synchronous motors have little rotary rectifier discs, compact constructions and electrical connections. The fixed components and the warmth sink are integrated, which is reliable in operation, minimal in failure price, and practical in installation and servicing.
