This is the simplest design where RUN winding and START winding are connected in parallel and 90° electrically apart.
both the windings will be energized with the in RUN winding lags the in the START winding by about 30° electrically.
the switch will close the circuit to get ready for the next starting of the motor..
By using the centrifugal switch, Once the motor has reached 75% of the rated speed, the capacitor and the START winding will be disconnected from the circuit, or current relay. .
the magnetic field being generated will cause the motor to continue running.
This motor design is similar to the capacitor-start design except that there is capacitor known as RUN capacitor.
the switch will be open to disconnect the START from the circuit.
RUN capacitor helps to correct the factor of the circuit making it more efficient.
This motor does not have any switch and the START winding, RUN winding and RUN capacitor are active whenever the motor is ON..
