SD series cage asynchronous motor and SDR series wound rotor asynchronous motor can be used in coal mining, machinery industry, power plant and other industrial and mining enterprises to drive various machinery, such as fans, compressors, pumps, crushers, ball mills, Cutting machine tools, transportation machinery, etc.

   The motor is generally self-ventilated and should be installed in a working environment with an altitude of no more than 1000 meters, an ambient temperature of 0 °C to +40 °C, clean air, no dust or water vapor, acid, alkali and other corrosive gases and explosive gases. Indoor.

    The rated voltage is 380V, 6000V, the rated frequency is 50HZ, the working mode is continuous use, and the winding insulation is Class B.

   The output end of the stator is installed in the junction box on the side of the base. From the extension end of the shaft, the junction box is located on the right side of the motor base, and can also be placed on the left side according to user requirements. The rotor outlet end is fixed to the collector ring assembly.

   SD, SDR electric can not bear the axial thrust of the transmission machinery, and can only be mechanically coupled with the elastic coupling.

   The SD motor allows direct full-voltage starting. If the grid capacity is limited and direct full-voltage startup is not allowed, a reduced voltage start can be used, but at this time the starting torque will decrease in the square of the starting voltage.

   When starting the SDR motor, the starting varistor must be connected to the rotor circuit in advance, and it is not allowed to directly short-circuit the rotor winding.
