TDMK AC Reversible Synchronous Motor IP55 For Mining Mill

TDMK Ac Synchronous Motor For Mining Mill Reversible Synchronous Motor

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.

The ventilation mode of TDMK(TM) three-phase synchronous motor for mine mill is open type natural ventilation or can be made into fully enclosed duct ventilation type.

Frame: welded with steel plates, the lower part of the frame is the outlet end of the motor.

Stator: The stator core is made of 0.5mm thick low-loss silicon steel sheet punched and stacked in a fan shape. The core segments are separated by air ducts. The windings are formed by double-stacked short-distance coils, using B-class insulation or F-class insulation. The temperature rise is assessed according to the B level to help prolong the service life: the winding ends are reliably fixed and bound, and are treated with a vacuum pressure intrusion solvent-free paint process. Withstand voltage test, the motor has excellent and reliable insulation performance, good mechanical strength and strong moisture resistance.

Rotor: The magnetic poles are punched from steel plates and mounted on the rotor yoke together with the magnetic pole coils. The magnetic pole coils are B-class or F-class insulation. When the user adopts a pneumatic clutch, the shaft design or shaft punching form can be selected according to the user's requirements. .

TDMK series motors are mainly used to drive large AC three-phase synchronous motors used in mining mills, mainly to drive grid-type ball mills, rod mills, coal mills, etc.
