Purpose-built HVAC motor

The FASCO D125 is a single-phase shaded-pole motor rated at one-fiftieth horsepower with a nameplate speed of 1,500 rpm. It operates on 115 V AC at 60 Hz and draws 0.8 A at full load, delivering 10 W of mechanical output. The 3.3 frame uses a closed-base steel housing with stud mounting for direct replacement in compatible air-over applications.

Suits direct-drive fan replacements.

Technicians servicing residential or light-commercial air-handling units that specify a 3.3 frame, CCWSE rotation and auto-reset thermal protection will find this motor a drop-in match. Installations requiring multi-speed operation, reversible rotation, 208 V or 200 V supply, or a higher service factor should select a different model.

Steady output within rated thermal envelope

The totally enclosed air-over design relies on the driven airflow for cooling, so continuous duty at 40 °C ambient is sustained only when the motor remains in the airstream. Auto thermal protection interrupts power if winding temperature exceeds the Class B limit, then restarts once the motor cools, preventing nuisance trips during normal cycling.

Questions about this item

What voltage supply must my HVAC unit provide for this 115V shaded-pole motor?

The motor runs on 115V AC at 60 Hz and draws .8 A at full load; it is not usable at 200V or 208V.

Will the CCWSE shaft rotation and 3.3 frame match the blower wheel I already have?

The motor has a 3.3 frame with stud mounting and CCWSE rotation; verify your wheel’s bore and rotation direction before installing.

How can I confirm the motor is operating correctly once installed?

It should spin at 1500 rpm nameplate speed, stay within the 40 °C max ambient limit, and the auto thermal protector should not trip under normal load.
