The TDMK series large AC Three-phase Synchronous Motor for mining mill machine is the core driving machine for mining and cement industry, which is also the main product since our company was founded in year 1950. Due to this series (including TDMK series brush synchronous motor and TMW series brushless synchronous motor) big starting torque feature, it can be widely used in mining and cement industry, mainly used to drive low speed, high capacity machines like grate ball mill, rod mill and coal mill etc.
with our sixty to seventy years of experience in manufacturing medium and large high-voltage AC motor. By using advanced technique comprehend from domestic and abroad, after modern field-circuit electromagnetic calculation and optimized design on dissipation, ventilation circuit and windage resistance, component intensity of the motor, our products are high efficiency, low noise, low vibration, high reliability and easy to install and maintain.
The first TDMK series 2000 kW 60-pole low speed synchronous motor in China, manufactured by Shenyang Electric Machine Factory in 1990.
|rated voltage:||3kV~11kV motors series with multiple voltage grades.
The motor can be started directly at full voltage or soft start at a lower voltage.
|Pole number:||60, 48, 40, 36, 32, 30, 24, 20|
|speed:||100, 125, 150, 167, 187.5, 200, 250, 300r/min|
|frame size:||4250, 3250, 2900, 2600, 2150, 1730|
|protection grade:||IP00, IP20, IP21, IP23, IP44, IP54, IP55|
The electric motor can be divided into drilled shaft motor and non-drilled shaft motor,
the drilling shaft motor need to be applied with air clutch, while the non-drilling motor
has higher starting ability.
|at rated voltage:||Starting torque ratio 1.7 (0.6 with drilled shaft)
Pull-in torque ratio 1.0 (0.6 with drilled shaft)
Pull-out torque ratio 2.0
Starting current ratio 7.0
The outdoor series (W), humid tropics series (TH), humid tropics outdoor series (THW) motor performance index, installation and volume dimension are the same as the basic series motor that they are derived from.
