The Evergreen CM motor is made with the same field-proven, high-efficiency ECM technology that has been used for more than 20 years in new HVAC equipment. It features flexible control methods to help the installer balance airflow in HVAC systems such as VAV (Variable Air Volume) boxes and Packaged HVAC systems. The Evergreen CM is designed as a direct replacement for OEM (Original Equipment Manufacturer) Genteq model X13 (Constant Torque ECM) or as a field replacement for existing PSC (Permanent Split Capacitor) motors.

Motor mounts for Evergreen® motors


All Evergreen® motors are NEMA® 48-frame (5.6" diameter). If the motor you're replacing has the same frame dimensions and uses a belly band mount, an Evergreen motor will fit in the existing mount.

A new motor mount may be required if the old mount is connected to the motor around the bearing (resilient mount) or welded or bolted directly to the motor shell.

To determine the bolt hole diameter needed, measure the diameter of the air inlet. The bolt hole dimension must be larger than this dimension.
