TDMK large synchronous motors have a cylindrical shaft extension end. The direction of rotation should be in accordance with the direction specified by the index plate. The direction of rotation is generally counterclockwise from the slip ring end, it can also be made clockwise according to requirements.
When the motor and the mill are connected by a coupling, the motor shaft extension cannot bear the applied radial or axial force. The excitation system of this series of motors adopts SCR excitation device.
The motor allows direct starting at full voltage. 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.
Stator lead wire: There are six lead wire heads, which are marked U1, V1, W1, U2, V2, W2, and are led out from the outlet clamp at the lower part of the base by using high-voltage rubber cables.
