How a current relay operates to remove the start winding from the circuit?

A current relay operates by monitoring the current flowing through the start winding of a motor. When the motor reaches a predetermined speed, the current in the start winding decreases. This drop in current activates the relay, which opens its contacts and disconnects the start winding from the circuit, allowing the motor to run efficiently on the run winding alone. This process helps prevent overheating and damage to the start winding.
