i need to know this b/c im having a test on it so someone please help me out so i can understand it better
A permanent split capacitor (psc) motor is a single phase AC motor that has a capacitor that provides a phase shift for the current in the auxiliary windings. The capacitor and the auxiliary winding are connected all of the time and not just while the motor is accelerating to speed when starting. The blower in an HVAC air handling unit has a low starting torque requirement and increasing torque proportional to the square of speed as it accelerates. That means that a psc motor, can be designed to provide optimum performance at full speed and still start adequately. The psc motor is less complex, less expensive, more efficient, more reliable and quieter than a capacitor start motor.
