Are ECM blower 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.

What is Evergreen motor?

Evergreen® IM motors are high-efficiency ECM replacement motors designed to replace factory PSC (Permanent Split Capacitor), direct drive, indoor blower motors in HVAC systems. They are constructed with more than 20 years of proven ECM technology and reliability. Features.

Is an X13 motor an ECM motor?

Both variable speed and X13 motors are ECM or “electronically commutated motors,” which means that the DC power that drives them is electronically switched from positive to negative to spin the motor.

How long should a ECM motor last?

In general, an ECM installed in a typical HVAC application should deliver about 90,000 hours, or the equivalent of 10 years of service. A PSC motor has an expected service life of only 50,000 hours or eight years before replacement is required.

What does ECM stand for HVAC?

Electronically commutated motor
Electronically commutated motor (ECM) technology has been in use for over 20 years in the HVACR industry. Predominantly used in variable-speed indoor blower motors, ECMs were introduced in 1987 by GE (rebranded Genteq™ in 2009).

How do I test my HVAC ECM motor?

This plug carries control signals between the IFC and the ECM Motor. If the motor does not run, make sure you have power to the IFC board and then check the voltage between pins 4 and 5 of the 5 pin plug on the motor. You should read 115 volts. If voltage is not present, the motor will not run.

What is the difference between X13 and ECM?

The X13™ adjusts its speed (High, Medium High, Medium, Medium Low, Low) based on changes to static pressure by only monitoring changes in torque. This ‘standard ECM’ motor is much more efficient than PSC motors, but less efficient when compared to ECM variable speed motors.

Do X13 motors need to be programmed?

The new X13 high efficiency constant torque motors will require the new Pocket Programming Module. For the first time the programmer will be available directly from ServiceFirst.

What causes ECM motors to fail?

A major cause of failure occurs when a blower is applied to an application with static pressure above . 8” WG. This not only shortens the life of an ECM, but also a PSC. With an ECM this will cause a failure of the metal oxide varistor (MOV), a disk in the controller.
