OEM Replacement Motor 3.3 Frame

The FASCO D137 is a shaded-pole motor designed as an OEM replacement for compatible fan assemblies. It operates on 115V AC single-phase power at 60 Hz and delivers two speed settings with a nameplate rating of 500 RPM. The motor provides 20 W output across 1/30 hp and 1/65 hp ratings.

Sustained Load Operation

Automatic thermal protection and Class B insulation support continuous duty at up to 40 °C ambient temperature. The totally enclosed air-over enclosure relies on the host fan's airflow for cooling during extended run times. A 1.0 service factor indicates rated output without overload margin under steady conditions.

Stud Mounting and Shaft Detail

Stud mounting allows direct attachment to the original equipment housing without additional brackets. The shaft rotates clockwise when viewed from the shaft end to match the required fan blade direction. The unit is not usable at 200V or 208V, confirming strict 115V supply compatibility.

Questions about this item

How much heat does the 20 W motor add when running continuously?

At 20 watts output the motor adds only a small amount of heat to the airstream; the totally enclosed air-over design relies on the fan airflow to keep the windings within the 40 °C ambient limit.

What mounting hardware must I already have to install the 3.3 frame motor?

The motor uses a stud mounting pattern; you need matching stud holes or a bracket that accepts the 3.3 inch frame studs.

Will the 115 V shaded-pole motor run on my existing 208 V or 200 V supply?

No — the motor is rated only for 115 V AC and is explicitly marked not usable at 208 V or 200 V.
