Mining Mill Three Phase AC Synchronous Motor IC37 IC81W

TDMK400KW AC Synchronous Motor for mining mill machine

TDMK(TM) three-phase synchronous motors for mine mills are specially designed for rolling mills. The startup mode is full pressure startup. If the grid capacity is insufficient, the voltage can be appropriately reduced to start. The manufacture conforms to GB755 "Basic Technical Requirements for Rotating Electric Machines" and JB8/DQ3449 "Technical Conditions for TK Series Large Three-phase Synchronous Motors".

TDMK(TM) three-phase synchronous motor for mine mill is suitable for altitude not exceeding 1000m and cooling medium temperature not exceeding 40 degrees. The rated voltage of this series of motors is 6000V, and 3000V and 10000V can also be provided according to user requirements. The allowable voltage deviation range is +5%, the rated power frequency is 50Hz, and the rated power factor is 0.9 (leading).

The three-phase synchronous motor for TDMK(TM) mine mill has a cylindrical shaft extension end, and its rotation direction should be rotated in the direction specified by the sign. The rotation direction is generally counterclockwise when viewed from the collector ring end. clockwise. When the motor and the mill are connected by a coupling, the motor shaft extension cannot bear the external radial force or axial force.

TDMK(TM) three-phase synchronous motor excitation system for mine mill adopts thyristor excitation device. The motor allows full voltage direct starting. If the user's power grid does not allow full voltage to start directly, the 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. Stator leads: There are six leads, U1, VI, W1, U2, V2, W2 respectively, and high-voltage rubber cables are used to lead out on the clips at the bottom of the frame, and can also be made into a junction box for wiring as required.
