Current in I/M

The current flowing will be dependent on the shaft load, but the magnetising current in star will be one third of the magnetising current in delta. If the shaft load is light, (less than one third of motor rating) the work current in star will be similar to that in delta.

If the shaft load is high, the motor will begin to stall in star and the work current will increase more than the current in delta.


For a more accurate answer, we need to know more about the conditions.

Best regards,
