TDMK series synchronous motors are designed for driving large-scale synchronous motors of mine mills. The rated parameters of this series of motors are rated frequency of 50Hz; rated voltages are 6000V and 10000V; power factor: 0.9 (leading); the rating is continuous. The structure and installation type is IM7311; the cooling method is IC0; the protection degree of the enclosure is IP20, the ventilation mode is open natural ventilation or it can be made into fully enclosed pipeline ventilation. The TDMK series motors are suitable for use at temperatures not exceeding 1000 m and cooling media temperatures not exceeding 40 degrees. The TDMK series motor excitation system uses a thyristor excitation device. The motor allows full voltage to be started directly. If the user's power grid does not allow full voltage to start directly, a step-down start can also be used. At this time, the starting current of the motor decreases in proportion to the terminal voltage, and the starting torque decreases in proportion to the square of the terminal voltage. The TDMK series motor has a cylindrical shaft extension end, and its rotation direction should be rotated in the direction specified by the sign. The direction of rotation is generally counterclockwise from the end of the collector ring, and can also be made clockwise according to requirements. When the motor and the mill are coupled by a coupling, the motor shaft cannot be extended to withstand external radial or axial forces.
The TDMK series motors are mainly suitable for large AC three-phase synchronous motors used in transmission mine mills. The main transmission lattice ball mill, rod mill, coal mill and so on.
