1TDMK/TM sequence synchronous motors (which includes TDMK collection brushed synchronous motors and TMW series brushless synchronous motors) are broadly used in mining, cement and other industries. It is mainly employed to generate mechanical products with reduce velocity and greater power, and the major transmission grid kind ball mill, rod mill, and coal mill. This series of motors adopts new technologies, new materials, new procedures, exquisite substance variety, and advanced manufacturing. It has the attributes of little size, mild weight, early appearance, higher performance, lower sounds, minimal vibration, risk-free and reputable procedure, and practical and protected use and upkeep. .

This series of synchronous motors are divided into two types: shaft drilling motors and shaft non-piercing motors. The shaft punching motor must be used with a pneumatic clutch (the pneumatic clutch demands to be geared up by the person), and the shaft not punching motor demands a higher commencing functionality (you should specify when ordering)

3CZPT characteristics
TDMK sequence shaft-punching synchronous motors, whose commencing method is utilized with pneumatic clutch, can understand the segmented starting of synchronous motor and mill load, with minor affect on the user’s electricity grid, and permitting entire voltage immediate starting.
TDMK series shafts are not perforated synchronous motors with extremely higher starting performance, which can fulfill the demands of users to start off directly with load.
TDMK sequence synchronous motors have large functioning security and powerful overload capability. When the grid voltage drops or the motor is overloaded, the excitation method can automatically change and employ powerful excitation to ensure the security of the motor.
The defense unit is advanced and comprehensive. Stator windings and bearings are geared up with temperature detection devices, which can keep an eye on, alarm and trip.
TMW sequence brushless synchronous motors, its brushless excitation program adopts a rotating rectifier, a rotating armature AC primary excitation equipment, and a coaxial integrated framework with the synchronous motor. It has automatic de-excitation protection and automated excitation at the greatest time of polarity. The intelligent automatic handle purpose of load out-of-action re-stepping and out-of-step protection has a large diploma of steadiness and quickly response overall performance, and the electrical power source program voltage transiently fluctuates and brings about oscillation or the pushed mechanical equipment and procedure movement seem When the transient disturbance is strong, the motor has the perform of automated smart protection and handle, which has a much smaller sized impact on the procedure of the motor than the traditional brushed synchronous motor.

four. Construction 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 center of the tail of the shaft, and an air hole at the shaft extension conclude for installing a pneumatic clutch. The shaft of TMW collection brushless synchronous motors is outfitted with a coaxial rotating rectifier and rotating armature AC major exciter, which replaces the collector ring and brush structure of TDMK sequence motors to give excitation for the motor.
Stator: The stator body is welded by metal plate, and the motor stator outlet is led by high-voltage rubber cable. The outlet wire can be led out from the base component or from the primary junction box on the electrical aspect.

The stator main is laminated with minimal-reduction silicon steel sheets, and the main sections are separated by radial ventilation ducts.
The stator winding is F quality insulation, and the temperature rise is assessed in accordance to B quality to help prolong the support existence. Making use of VPI total dipping paint treatment, it has higher electrical efficiency, mechanical power, bonding functionality, 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 person adopts the pneumatic clutch, the shaft can be punched according to the user’s demands. The rotor support is produced of forged steel.
TDMK sequence brushed synchronous motors are geared up with metal slip rings on the shaft. An AC exciter and a rotating rectifier plate are put in on the shaft of the TMW sequence brushless synchronous motor. The base plate is a metal plate welded construction, which is welded with a twenty-30mm steel plate.

Adopt seat variety spherical sliding bearing. The bearings are insulated to prevent shaft currents. Use new lubricating oil and slim-walled bearing alloy bushes, and set electromagnetic centerline symptoms.
TMW series brushless synchronous motors have little rotary rectifier discs, compact structures and electrical connections. The mounted parts and the warmth sink are built-in, which is reliable in procedure, lower in failure fee, and hassle-free in set up and servicing.
