Are all ECM motors variable speed?
Accordingly, what is the difference between an ECM motor and a variable speed motor?
Both variable speed and X13 motors are ECM or “Electronically Commutated Motors,” This means the DC power that drives them is electronically switched from positive to negative to spin the motor. The primary difference is the type of inputs to the motor control.
Subsequently, question is, do ECM motors have capacitors? ECMs are a type of DC motor. Permanent split capacitor (PSC) motors, often used in conjunction with electronic SCR motors, are somewhat inefficient when used in air control systems. This is because the fan motor noise requires the motor to run at less than a full load.
Also question is, are ECM motors reliable?
Not only are they simple and inexpensive, but they've proven to be an extremely reliable component. The average lifespan of a PSC motor is around 40,000 hours, though an ECM surpasses it at 90,000 hours.
