Brief Introduction
Simo TDMK series of AC synchronous permanent magnet electric motor is a large size three phase synchronous electric motor used in mining machine. It mainly applies in less dust indoor environment where altitude is not exceed 1000m, ambient temperature not exceed 40℃ which is free from steam, corrosive gases of acid and alkali. This series of motor allows full-voltage direct start. It can adopt reduced-voltage starting if full-voltage starting is not allowed by user power grid, hence, the starting current and terminal voltage decrease in direct proportion and starting torque and terminal voltage decrease in inverse proportion.

TMDK Introduction
TDMK series AC synchronous permanent magnet electric motor is most widely applied large size high voltage synchronous motor. Its rotation direction can be clockwise also anti-clockwise seeing from the slip ring side.
When the motor is coupling the milling machine, extra axial force or radial force the DE end of the motor is not allowed.
TDMK series motor starting method is full voltage starting. If the power is not enough, the motor can be started with reduced voltage properly.
The starting current and the starting torque will be lower as well.
The Stator out leads cables: 6 wiring(U1,V1,W1,U2,V2,W2)
Sat sleeve bearing is adopted: oil ring bearing or multiplex bearing. There is a rubber pads between bearing and the motor frame to avoid the shaft current.
Structure Introduction
Frame: integral construction welded by steel plate, outlets is at the bottom of the frame
Stator: laminated by 0.5mm silicon steel fan shaped lamination. The core segments are separated by radial duct pieces. The winding is molded double-stacked short-pitch coils. The insulation class can be B or F.
Rotor: The poles are punched from steel plates and mounted on the rotor yoke together with the pole coils.
Advantages
TDMK series of AC synchronous permanent magnet electric motor has characteristics of large torque, constant speed and it can remain constant synchronous speed when load changes dramatically.
Operation Conditions
Ambient temperature is -15℃~+40℃; Altitude ≤1KM; and monthly average air humidity ≤90% (If temperature is 25℃).
Great quality is the secret that Simo motor can be outstanding all through the 67 years in electric motor manufacturing industry. We have really strict control systems on the material suppliers choosing and reviewing, material inspection, processing checking, motor testing, testing , packing and transporting.
Application
TDMK series of AC synchronous permanent magnet electric motor mainly applies in mechanical equipment of lower drive speed and large power among mine and cement industries, such as grate ball mill, rod mill, coal mill, etc.
