PSC Motor vs Constant Torque Motor vs Variable Speed Motor | Comparison Video

This is a comparison video of a PSC Motor vs Constant Torque Motor vs Variable Speed Motor.  We will explain what a variable speed motor is, and how it is different from a constant torque motor.  We will also discuss the difference between a regular permanent split capacitor motor and an ECM motor.  I'd like to discuss the benefits of a constant torque motor and if it can save money for you.

PSC motors are simple, fairly inexpensive, moderately efficient motors with a reputation for being loud and not very dynamic. They also come hitched with the always unpredictable capacitor, which can go out due to overheating. 

ECM constant torque and ECM variable-speed motors are pretty complex in design, high-efficiency motors, known for being much quieter on start-up and shutdown. Their ability to control airflow better than PSC motors makes them smart motors because they can ramp up power as needed (the variable speed more so than the constant torque motor.)  All of this comes with a higher price tag, though, when it comes to repairs.
