Electrical faults

Note

If you are operating the motor with a converter, the operating instructions of the converter must
also be observed if electrical faults occur.

Table 8-1

Electrical faults

↓ Motor fails to start

↓ Motor accelerates sluggishly

↓ Rumbling noise during startup

↓ Rumbling noise during operation

↓ High temperature rise during no-load operation

↓ High temperature rise with load

↓ High temperature rise of individual winding sections

Possible causes of faults

Remedial measures

Overload

Reduce the load.

Interrupted phase in the supply cable

Check the switches and cables.

Interrupted phase in the feeder cable af‐
ter switching on

Check the switches and cables.

Mains voltage too low, frequency too
high

Check the power supply conditions.

Mains voltage too high, frequency too
low

Check the power supply conditions.

X Stator winding incorrectly connected

Check the winding connection in the terminal
box.

X Winding short circuit or phase short cir‐

cuit in stator winding

Determine the winding resistances and insulation
resistances. Carry out repair work after consulta‐
tion with the manufacturer.

Incorrect direction of rotation

Check the connection.
