1TDMK/TM sequence synchronous motors (such as TDMK collection brushed synchronous motors and TMW series brushless synchronous motors) are commonly used in mining, cement and other industries. It is mainly utilized to push mechanical gear with lower pace and higher energy, and the primary transmission grid kind ball mill, rod mill, and coal mill. This series of motors adopts new technological innovation, new components, new processes, exquisite materials selection, and refined manufacturing. It has the attributes of small dimensions, light-weight bodyweight, early physical appearance, large performance, lower sound, lower vibration, safe and reputable procedure, and convenient and protected use and upkeep. .
This collection of synchronous motors are divided into two types: shaft drilling motors and shaft non-piercing motors. The shaft punching motor have to be employed with a pneumatic clutch (the pneumatic clutch needs to be prepared by the consumer), and the shaft not punching motor demands a increased commencing overall performance (make sure you specify when ordering)

3CZPT characteristics
TDMK collection shaft-punching synchronous motors, whose starting technique is utilized with pneumatic clutch, can recognize the segmented beginning of synchronous motor and mill load, with small impact on the user’s electricity grid, and allowing complete voltage immediate commencing.
TDMK sequence shafts are not perforated synchronous motors with quite high starting up overall performance, which can meet up with the wants of consumers to begin directly with load.
TDMK sequence synchronous motors have large operating security and sturdy overload capacity. When the grid voltage drops or the motor is overloaded, the excitation method can instantly adjust and apply powerful excitation to make certain the stability of the motor.
The security gadget is advanced and full. Stator windings and bearings are geared up with temperature detection units, which can keep track of, alarm and excursion.
TMW series brushless synchronous motors, its brushless excitation program adopts a rotating rectifier, a rotating armature AC principal excitation equipment, and a coaxial built-in structure with the synchronous motor. It has automatic de-excitation defense and computerized excitation at the best time of polarity. The clever computerized management purpose of load out-of-step re-stepping and out-of-phase protection has a high diploma of steadiness and quick response functionality, and the energy supply method voltage transiently fluctuates and leads to oscillation or the pushed mechanical equipment and process movement appear When the transient disturbance is sturdy, the motor has the function of automatic smart safety and handle, which has a considerably smaller impact on the operation of the motor than the classic 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 hole (intake gap) at the center of the tail of the shaft, and an air gap at the shaft extension conclude for installing a pneumatic clutch. The shaft of TMW collection brushless synchronous motors is geared up with a coaxial rotating rectifier and rotating armature AC main exciter, which replaces the collector ring and brush structure of TDMK sequence motors to provide excitation for the motor.
Stator: The stator frame is welded by metal plate, and the motor stator outlet is led by large-voltage rubber cable. The outlet wire can be led out from the base component or from the principal junction box on the electrical side.
The stator core is laminated with lower-decline silicon steel sheets, and the main sections are separated by radial air flow ducts.
The stator winding is F quality insulation, and the temperature increase is assessed according to B grade to support prolong the support existence. Employing VPI all round dipping paint treatment method, it has higher electrical performance, mechanical strength, bonding efficiency, humidity resistance and thermal balance.
The rotor magnetic pole core is made of laminated steel 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 help is created of forged metal.
TDMK collection 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 collection brushless synchronous motor. The base plate is a steel plate welded framework, which is welded with a twenty-30mm metal plate.
Undertake seat variety spherical sliding bearing. The bearings are insulated to avert shaft currents. Use new lubricating oil and slim-walled bearing alloy bushes, and set electromagnetic centerline indicators.
TMW sequence brushless synchronous motors have modest rotary rectifier discs, compact constructions and electrical connections. The fastened elements and the heat sink are built-in, which is reputable in operation, lower in failure price, and convenient in set up and routine maintenance.
