1TDMK/TM collection synchronous motors (like TDMK collection brushed synchronous motors and TMW series brushless synchronous motors) are extensively employed in mining, cement and other industries. It is primarily utilised to drive mechanical gear with reduced pace and increased electricity, and the principal transmission grid type ball mill, rod mill, and coal mill. This sequence of motors adopts new technology, new supplies, new processes, beautiful content variety, and innovative manufacturing. It has the qualities of little dimensions, light bodyweight, early look, substantial efficiency, reduced noise, lower vibration, risk-free and reputable operation, and practical and protected use and routine maintenance. .
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 utilized with a pneumatic clutch (the pneumatic clutch demands to be well prepared by the person), and the shaft not punching motor wants a increased beginning functionality (you should specify when purchasing)

3CZPT qualities
TDMK series shaft-punching synchronous motors, whose starting technique is employed with pneumatic clutch, can realize the segmented beginning of synchronous motor and mill load, with minor affect on the user’s electricity grid, and enabling complete voltage immediate starting up.
TDMK series shafts are not perforated synchronous motors with really substantial commencing overall performance, which can meet up with the wants of users to begin directly with load.
TDMK series synchronous motors have higher functioning security and powerful overload ability. When the grid voltage drops or the motor is overloaded, the excitation technique can instantly adjust and implement powerful excitation to make certain the security of the motor.
The safety device is advanced and total. Stator windings and bearings are outfitted with temperature detection devices, which can keep an eye on, alarm and journey.
TMW collection brushless synchronous motors, its brushless excitation technique adopts a rotating rectifier, a rotating armature AC principal excitation equipment, and a coaxial built-in framework with the synchronous motor. It has automated de-excitation defense and automated excitation at the ideal time of polarity. The clever automated management operate of load out-of-phase re-stepping and out-of-step security has a higher diploma of security and rapidly response efficiency, and the electricity offer method voltage transiently fluctuates and brings about oscillation or the driven mechanical equipment and approach stream look When the transient disturbance is strong, the motor has the operate of computerized smart security and management, which has a significantly smaller sized influence on the procedure of the motor than the standard brushed synchronous motor.
four. 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 middle 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 equipped with a coaxial rotating rectifier and rotating armature AC primary exciter, which replaces the collector ring and brush composition of TDMK series 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 main junction box on the electrical side.
The stator main is laminated with reduced-decline silicon steel sheets, and the core sections are divided by radial ventilation ducts.
The stator winding is F quality insulation, and the temperature increase is assessed according to B grade to aid prolong the service lifestyle. Utilizing VPI total dipping paint remedy, it has higher electrical efficiency, mechanical strength, bonding overall performance, dampness resistance and thermal stability.
The rotor magnetic pole main is made of laminated steel plates, and the magnetic pole coils are insulated with class F.
When the user adopts the pneumatic clutch, the shaft can be punched in accordance to the user’s requirements. The rotor assist is produced of forged steel.
TDMK series brushed synchronous motors are equipped with steel slip rings on the shaft. An AC exciter and a rotating rectifier plate are installed 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 metal plate.
Adopt seat type spherical sliding bearing. The bearings are insulated to avert shaft currents. Use new lubricating oil and thin-walled bearing alloy bushes, and established electromagnetic centerline indications.
TMW sequence brushless synchronous motors have modest rotary rectifier discs, compact buildings and electrical connections. The fastened elements and the heat sink are integrated, which is trustworthy in operation, minimal in failure rate, and practical in installation and routine maintenance.
