HVAC unit bearing motor

This Dayton motor is a shaded-pole unit bearing design rated at 1/370 horsepower for 115 V AC single-phase supply. It targets HVAC control applications such as damper actuators, small fans or valve drives where a compact, totally enclosed air-over motor is required.

Capacity and headroom

The motor delivers 2.3 W output at 1,550 rpm nameplate speed while drawing 0.25 A full-load current. Its 1.0 service factor provides no overload margin, so continuous operation beyond nameplate load will exceed thermal limits.

Thermals noise and power

Class A insulation and impedance thermal protection support a maximum ambient temperature of 40 °C in horizontal or shaft-up vertical mounting. The totally enclosed air-over enclosure relies on external airflow for cooling, keeping internal losses contained during normal duty.

Questions about this item

Will this 115 V shaded-pole motor run on the same circuit as my older 115 V HVAC components?

Yes, it operates on standard 115 V AC at 60 or 50 Hz and draws only 0.25 A at full load, so it shares a circuit with other 115 V equipment.

How can I confirm the motor is turning correctly after installation?

The shaft should rotate clockwise when viewed from the lead end at 1550 rpm with the motor running horizontally or vertically shaft-up.

What comes in the box and what must I supply separately?

The unit bearing motor itself is included; mounting hardware, wiring, capacitors and any duct adapters are not supplied.
