HVAC Shaded-Pole Motor for Fan

The FASCO D332 is a single-phase shaded-pole motor rated at 1/25 hp with a nameplate speed of 1550 rpm. It operates on 115 V AC at 60 Hz and draws 1.5 A at full load. The 3.3 frame uses steel construction with an open air-over enclosure and stud mounting. It is not usable at 200 V or 208 V.

Thermals and Electrical Draw in Normal Operation

The motor carries a 1.0 service factor and Class B insulation with automatic thermal protection. Maximum ambient temperature is 40 degrees C. Output power is 30 W. The closed-base design and open air-over enclosure rely on the application airflow for cooling during continuous duty.

Two-Speed CWSE Rotation Decides Fit

This unit provides two selectable speeds and a fixed clockwise shaft-end rotation. Buyers who need counter-clockwise rotation, a different speed count, or voltage compatibility at 200 V or 208 V cannot use this motor. Verify the required rotation and speed configuration before purchase.

Questions about this item

How is the FASCO D332 motor installed and what step is often missed?

The motor mounts via studs on a 3.3 frame; the step often missed is verifying the shaft rotation is CWSE before final tightening.

What maintenance or replacement will the FASCO D332 motor need later?

With auto thermal protection and Class B insulation rated for 40 °C ambient, the main future need is bearing lubrication or replacement if noise develops.

What limit appears first on the FASCO D332 under sustained use?

The 1.0 service factor means the motor cannot exceed its 1/25 hp / 30 W rating continuously; overheating protection will trip first at 40 °C ambient.
