AC65 motors are designed to resist damage caused by heat buildup and by "dirty voltage" spikes from lower speed operation while under torque load. Measuring 2.88 in. square at the endbell and 5.22 in. in length, these compact ac motors are suitable for commercial and industrial HVAC fans, commercial oven rotisseries, and other applications where speed fluctuations and heat are factors.

An all-aluminum frame and machined aluminum endbells add to the unit's overall rugged design. Inside the frame, cooling channels eliminate lint, dust, and debris buildup in the fins that can cause overheating and motor damage.
