damage to the motor. After the motor starts up via partial winding

of one second . Failure to comply can adversely affect the service
life of the motor.

Part winding 1 = 50% and part winding 2 = 50%.
This winding division reduces the start-up current needed for a part winding start to approx. 50% of
that for a direct start.
