Dayton 71633689M HVAC Motor 1/50 HP 1550 rpm 115V 3.3 Frame Fan Accessory

Dayton 1/50 HP HVAC Motor

The Dayton 71633689M is a single-phase shaded-pole motor rated at 1/50 HP and 1550 rpm on 115V AC. It draws 0.8 A at full load and fits a 3.3 frame with a closed-base, open air-over enclosure. The motor mounts via ring/stud in any orientation and runs continuously at up to 40 °C ambient with automatic thermal protection.

Best for direct-drive fan replacements

This motor suits technicians replacing a failed shaded-pole unit in residential or light-commercial air-handling equipment where a single-speed, clockwise-shaft motor is specified. It is not for applications that require reversible rotation, multiple speeds, or operation on 200 V or 208 V supplies. Builders needing higher torque, variable-speed control, or a different frame size should look at other motor types.

Rated for continuous low-torque duty

At 1/50 HP the motor comfortably drives small blower wheels and propeller fans within its 1550 rpm design point. Thermal protection is automatic and the insulation class B rating supports the stated 40 °C maximum ambient. Headroom ends when the load exceeds the 1.0 service factor or when the application demands operation beyond 115 V at 60 Hz.
