What is the difference between a PSC motor and an ECM?

A PSC (Permanent Split Capacitor) motor is a type of single phase induction motor that uses a capacitor in the circuit to produce a phase shift between the current in the main and auxiliary windings, producing a rotating magnetic field and allowing the motor to start and run.

An ECM (Electronically Commutated Motor) is a type of motor that uses electronic circuitry to control the speed and torque of the motor, rather than relying on mechanical commutation. This allows for precise control and improved efficiency, particularly at low speeds.

So, the key difference between PSC and ECM motors lies in their method of producing a rotating magnetic field and the control of their speed and torque. PSC motors use a capacitor to produce a phase shift, while ECM motors use electronic commutation.
