1TDMK/TM sequence synchronous motors (which includes TDMK series brushed synchronous motors and TMW series brushless synchronous motors) are extensively employed in mining, cement and other industries. It is largely utilised to travel mechanical tools with reduced velocity and greater electrical power, and the principal transmission grid sort ball mill, rod mill, and coal mill. This sequence of motors adopts new technology, new materials, new processes, exquisite material choice, and advanced manufacturing. It has the traits of modest dimension, gentle weight, early visual appeal, large performance, reduced sound, low vibration, risk-free and trustworthy procedure, and handy and safe use and servicing. .
This collection of synchronous motors are divided into two kinds: shaft drilling motors and shaft non-piercing motors. The shaft punching motor have to be utilised with a pneumatic clutch (the pneumatic clutch requirements to be prepared by the user), and the shaft not punching motor demands a greater commencing overall performance (make sure you specify when purchasing)

3CZPT characteristics
TDMK series shaft-punching synchronous motors, whose beginning strategy is utilised with pneumatic clutch, can understand the segmented starting up of synchronous motor and mill load, with minor impact on the user’s electrical power grid, and allowing full voltage direct beginning.
TDMK collection shafts are not perforated synchronous motors with really high starting functionality, which can satisfy the requirements of users to start off immediately with load.
TDMK sequence synchronous motors have large operating steadiness and sturdy overload capacity. When the grid voltage drops or the motor is overloaded, the excitation program can automatically alter and apply strong excitation to guarantee the steadiness of the motor.
The safety device is sophisticated and full. Stator windings and bearings are outfitted with temperature detection products, which can keep an eye on, alarm and trip.
TMW sequence brushless synchronous motors, its brushless excitation system adopts a rotating rectifier, a rotating armature AC main excitation device, and a coaxial built-in structure with the synchronous motor. It has automated de-excitation defense and computerized excitation at the best time of polarity. The intelligent computerized management function of load out-of-phase re-stepping and out-of-phase safety has a higher diploma of balance and quick response performance, and the electrical power supply technique voltage transiently fluctuates and causes oscillation or the driven mechanical tools and method stream appear When the transient disturbance is strong, the motor has the perform of automated smart defense and manage, which has a significantly smaller sized affect on the procedure of the motor than the conventional brushed synchronous motor.
four. Structure sort
The motor is composed of two pedestal bearings, stator, rotor and bottom plate.
The shaft drilling motor has a deep hole (intake hole) at the heart of the tail of the shaft, and an air hole at the shaft extension stop for putting in a pneumatic clutch. The shaft of TMW series brushless synchronous motors is geared up with a coaxial rotating rectifier and rotating armature AC main exciter, which replaces the collector ring and brush framework of TDMK collection motors to offer excitation for the motor.
Stator: The stator frame is welded by steel plate, and the motor stator outlet is led by high-voltage rubber cable. The outlet wire can be led out from the base part or from the principal junction box on the electrical aspect.
The stator main is laminated with minimal-loss silicon steel sheets, and the core sections are divided by radial air flow ducts.
The stator winding is F grade insulation, and the temperature increase is assessed according to B grade to aid prolong the service existence. Making use of VPI overall dipping paint treatment, it has substantial electrical overall performance, mechanical energy, bonding functionality, humidity resistance and thermal steadiness.
The rotor magnetic pole core is manufactured of laminated metal plates, and the magnetic pole coils are insulated with course F.
When the user adopts the pneumatic clutch, the shaft can be punched in accordance to the user’s needs. The rotor support is produced of cast steel.
TDMK sequence brushed synchronous motors are outfitted with steel slip rings on the shaft. An AC exciter and a rotating rectifier plate are installed on the shaft of the TMW sequence brushless synchronous motor. The base plate is a steel plate welded framework, which is welded with a 20-30mm metal plate.
Adopt seat variety 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 symptoms.
TMW sequence brushless synchronous motors have tiny rotary rectifier discs, compact buildings and electrical connections. The fastened elements and the warmth sink are integrated, which is dependable in operation, lower in failure charge, and convenient in set up and routine maintenance.
