What is a split capacitor?
A Permanent Split Capacitor (PSC) Motor is a type of single-phase AC motor; more specifically, a type of split-phase induction motor in which the capacitor is permanently connected (as opposed to only being connected when starting). A number of different types exist for single-phase induction motors.
How does a permanent split capacitor work?
A PSC motor uses a capacitor (a device that can store and release electrical charge) in one of the windings to increase the current lag between the two windings. Both the capacitor (auxiliary) winding and the main winding remain in the circuit the entire time the motor is running, hence the name “permanent.”
What does a permanent split capacitor motor have?
The Permanent Split Capacitor motor also has a cage rotor and the two windings named as main and auxiliary windings similar to that of a Capacitor Start and Capacitor Start Capacitor Run Motor. It has only one capacitor connected in series with the starting winding.
What is a PSC motor used for?
PSC motor (permanent split capacitor) – Runs at a constant speed. ECM motor (electronically commuted motor) – Runs at a variable speed. This provides several benefits, including energy savings, lower need for maintenance, improved comfort and better airflow and indoor air quality.
Is permanent split capacitor motor?
A permanent split capacitor (PSC) motor is a type of single-phase induction motor. The permanent split-phase induction motor consists of a squirrel cage rotor and the stator has two windings, viz. starting or auxiliary winding and main or running winding.
Why is it called a split-phase motor?
In a split-phase induction motor, the starting and main current get split from each other by some angle, so this motor got its name as a split-phase induction motor.
How to wire a split capacitor motor?
Used in fans and blowers in heaters and air conditioners.
