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.

Questions about this item

What voltage supply and mounting style does the 71633689M motor require?

It runs on 115 V AC single-phase power and mounts with a ring/stud arrangement that works at any angle.

Will the 3.3 frame motor fit the same bracket as my old 3.3 frame unit?

Yes, the 3.3 frame size matches the industry standard, so existing ring/stud brackets line up directly.

How can I confirm the motor is turning the right way once wired?

The shaft should rotate clockwise when viewed from the shaft end; if it runs counter-clockwise, swap the two supply leads.
