Can we start a 75 HP induction motor by a DOL starter?
Answer
Yes, you can start a 75 HP induction motor by a DOL starter.
Direct On-Line (DOL) starter is the most economical method to start low-rated induction motors (i.e., up to 1.5kW).
This starter applies full voltage to the induction motor.
Hence the rated full load current flows through the motor windings.
