FASCO D624 3.3 Inch Motor
The FASCO D624 is a 1/50 HP shaded-pole motor built for direct-drive blower applications in HVAC equipment. It runs on 230 V AC single-phase power at 60 Hz and rotates clockwise when viewed from the shaft end. The totally enclosed air-over enclosure suits indoor air-handling units.
Installation checks
Confirm your system supplies 230 V AC and that the motor is not required to operate at 208 V or 200 V. The 3.3 inch frame and ring/stud mounting must match the existing bracket, and the single 12 inch lead length should reach the wiring compartment. Ensure the shaft rotation direction matches the blower wheel design.
Sustained-load behaviour
Rated for continuous duty at a maximum ambient temperature of 40 °C, the motor uses Class B insulation and automatic thermal protection. The 1.0 service factor indicates no overload capacity beyond the 0.4 A full-load current. Nameplate speed is 550 RPM under steady-state conditions.

Questions about this item
What comes in the box with the FASCO D624 motor and do I need to buy a capacitor separately?
The motor ships as a single unit with 12 in leads; a capacitor is not required for this shaded-pole design.
Should I choose the 230 V version or a lower-voltage model for my 208 V supply?
The D624 is rated for 230 V only and is not usable at 208 V or 200 V.
What does the 1/50 HP rating mean for airflow in a typical furnace blower?
At 550 RPM and 0.4 A the motor delivers low-torque direct-drive airflow suited for small residential blowers.
