The 48YZ condenser fan motor is one such designation that technicians and facility managers occasionally encounter, particularly when replacing motors in older or OEM-specific equipment.
When a motor is described as a 5.6 inch condenser fan motor, the number refers to the diameter of the motor’s stator housing—the cylindrical body that contains the windings and core.
Despite the dimensional variations, most 48Y condenser fan motors share a common set of electrical and performance characteristics with the broader 48 frame family. These include:
