1TDMK/TM collection synchronous motors (including TDMK collection brushed synchronous motors and TMW series brushless synchronous motors) are widely used in mining, cement and other industries. It is mostly employed to travel mechanical products with reduce pace and greater energy, and the major transmission grid kind ball mill, rod mill, and coal mill. This collection of motors adopts new technologies, new components, new procedures, beautiful substance selection, and innovative manufacturing. It has the characteristics of tiny size, gentle weight, early physical appearance, higher efficiency, minimal noise, lower vibration, protected and reliable procedure, and handy and safe use and routine maintenance. .
This series of synchronous motors are divided into two kinds: shaft drilling motors and shaft non-piercing motors. The shaft punching motor should be used with a pneumatic clutch (the pneumatic clutch needs to be prepared by the person), and the shaft not punching motor wants a increased commencing overall performance (remember to specify when purchasing)

3CZPT characteristics
TDMK collection shaft-punching synchronous motors, whose commencing approach is utilised with pneumatic clutch, can comprehend the segmented beginning of synchronous motor and mill load, with small impact on the user’s power grid, and allowing complete voltage direct starting up.
TDMK collection shafts are not perforated synchronous motors with very high beginning performance, which can meet the wants of customers to start off right with load.
TDMK collection synchronous motors have substantial operating steadiness and strong overload capability. When the grid voltage drops or the motor is overloaded, the excitation technique can automatically change and implement powerful excitation to make certain the security of the motor.
The defense gadget is innovative and complete. Stator windings and bearings are equipped with temperature detection devices, which can check, alarm and trip.
TMW series brushless synchronous motors, its brushless excitation method adopts a rotating rectifier, a rotating armature AC principal excitation device, and a coaxial integrated framework with the synchronous motor. It has automated de-excitation safety and automated excitation at the very best time of polarity. The intelligent automatic management purpose of load out-of-stage re-stepping and out-of-action defense has a high degree of balance and fast response performance, and the electricity offer program voltage transiently fluctuates and leads to oscillation or the driven mechanical gear and approach stream seem When the transient disturbance is sturdy, the motor has the purpose of computerized clever security and management, which has a a lot smaller influence on the operation of the motor than the traditional brushed synchronous motor.
four. Structure kind
The motor is composed of two pedestal bearings, stator, rotor and bottom plate.
The shaft drilling motor has a deep hole (consumption hole) at the centre of the tail of the shaft, and an air hole at the shaft extension stop for setting up a pneumatic clutch. The shaft of TMW series brushless synchronous motors is outfitted with a coaxial rotating rectifier and rotating armature AC principal exciter, which replaces the collector ring and brush structure of TDMK sequence motors to supply excitation for the motor.
Stator: The stator body 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 foundation element or from the main junction box on the electrical facet.
The stator main is laminated with reduced-loss silicon steel sheets, and the main sections are divided by radial air flow ducts.
The stator winding is F quality insulation, and the temperature rise is assessed according to B quality to help increase the service lifestyle. Using VPI overall dipping paint treatment method, it has substantial electrical overall performance, mechanical power, bonding efficiency, humidity resistance and thermal stability.
The rotor magnetic pole main is produced 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 requirements. The rotor assist is manufactured of cast steel.
TDMK series brushed synchronous motors are equipped with steel slip rings on the shaft. An AC exciter and a rotating rectifier plate are set up on the shaft of the TMW series brushless synchronous motor. The base plate is a steel plate welded construction, which is welded with a 20-30mm steel plate.
Undertake seat kind spherical sliding bearing. The bearings are insulated to stop shaft currents. Use new lubricating oil and skinny-walled bearing alloy bushes, and established electromagnetic centerline indicators.
TMW series brushless synchronous motors have modest rotary rectifier discs, compact buildings and electrical connections. The fixed components and the warmth sink are integrated, which is reputable in operation, minimal in failure price, and hassle-free in set up and maintenance.
