1TDMK/TM series synchronous motors (like TDMK collection brushed synchronous motors and TMW collection brushless synchronous motors) are extensively employed in mining, cement and other industries. It is largely used to travel mechanical gear with reduced speed and larger electrical power, and the major transmission grid sort ball mill, rod mill, and coal mill. This collection of motors adopts new technological innovation, new components, new procedures, beautiful material selection, and advanced production. It has the attributes of tiny measurement, mild fat, early visual appeal, large efficiency, lower sounds, low vibration, protected and trustworthy operation, and handy and secure use and servicing. .

This collection 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 needs to be ready by the user), and the shaft not punching motor requirements a greater starting overall performance (make sure you specify when purchasing)
2Basic parameters

3CZPT traits
TDMK collection shaft-punching synchronous motors, whose beginning approach is utilized with pneumatic clutch, can comprehend the segmented starting up of synchronous motor and mill load, with tiny impact on the user’s electricity grid, and enabling entire voltage direct starting up.
TDMK sequence shafts are not perforated synchronous motors with extremely large commencing functionality, which can satisfy the demands of consumers to begin directly with load.
TDMK sequence synchronous motors have higher working balance and sturdy overload capability. When the grid voltage drops or the motor is overloaded, the excitation system can automatically alter and implement robust excitation to ensure the stability of the motor.
The security device is advanced and total. Stator windings and bearings are outfitted with temperature detection products, which can keep an eye on, alarm and trip.
TMW series brushless synchronous motors, its brushless excitation method adopts a rotating rectifier, a rotating armature AC major excitation device, and a coaxial built-in structure with the synchronous motor. It has automated de-excitation protection and automatic excitation at the very best time of polarity. The clever automated management purpose of load out-of-phase re-stepping and out-of-action security has a substantial degree of steadiness and fast reaction overall performance, and the electrical power provide system voltage transiently fluctuates and triggers oscillation or the pushed mechanical tools and method stream seem When the transient disturbance is robust, the motor has the purpose of automated clever security and manage, which has a a lot scaled-down influence on the procedure of the motor than the standard brushed synchronous motor.

4. Framework sort
The motor is composed of two pedestal bearings, stator, rotor and base plate.
The shaft drilling motor has a deep gap (ingestion hole) at the middle of the tail of the shaft, and an air hole at the shaft extension finish for installing a pneumatic clutch. The shaft of TMW series brushless synchronous motors is equipped with a coaxial rotating rectifier and rotating armature AC primary exciter, which replaces the collector ring and brush composition of TDMK collection motors to provide 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 foundation component or from the primary junction box on the electrical aspect.

The stator core is laminated with lower-decline silicon steel sheets, and the core sections are divided by radial ventilation ducts.
The stator winding is F grade insulation, and the temperature increase is assessed in accordance to B quality to support lengthen the provider existence. Making use of VPI general dipping paint remedy, it has substantial electrical functionality, mechanical strength, bonding overall performance, moisture resistance and thermal security.
The rotor magnetic pole main is manufactured 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 in accordance to the user’s needs. The rotor assist is manufactured of solid metal.
TDMK series brushed synchronous motors are geared up with metal 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 bottom plate is a metal plate welded construction, which is welded with a twenty-30mm steel plate.

Undertake seat sort spherical sliding bearing. The bearings are insulated to prevent shaft currents. Use new lubricating oil and thin-walled bearing alloy bushes, and established electromagnetic centerline indicators.
TMW collection brushless synchronous motors have little rotary rectifier discs, compact buildings and electrical connections. The fixed areas and the warmth sink are integrated, which is dependable in operation, lower in failure rate, and handy in installation and maintenance.
