Fasco D783 Motor

The Fasco D783 Motor is a high-performance 1/4 HP OEM replacement motor designed for demanding condenser fan and direct drive blower applications. Operating at 208-230V and a fixed speed of 1625 RPM, this 48 Frame motor features a 5.6-inch diameter and a Permanent Split Capacitor (PSC) design to provide superior electrical efficiency and high starting torque compared to shaded pole alternatives. Built for longevity in HVACR environments, the assembly includes sleeve bearings with an all-angle mounting capability and automatic thermal overload protection to prevent winding failure under high-ambient conditions. The 1/2" x 5.94" shaft includes a double flat for secure blower wheel or fan blade attachment. As a versatile service replacement motor, it is electrically reversible and compatible with systems originally utilizing Copeland 3047 or 050-0238-00 specifications. This open drip proof (ODP) unit requires a 5 MFD / 370V capacitor for proper operation.

Key Benefits for HVACR Contractors:

• Universal Versatility: Electrically reversible rotation and extended studs on both ends allow for flexible installation in various furnace and AC configurations.
• Rugged Build Quality: Constructed with a rolled steel frame and Class B insulation rated for 40°C ambient temperatures to handle continuous duty cycles.
• Precise OEM Fit: Direct cross-reference for common manufacturer parts, ensuring 1/2-inch shaft compatibility and standard 48-frame mounting dimensions.
• Enhanced Protection: Integrated thermally protected internal resets safeguard the motor against voltage fluctuations and mechanical overloads.

Common Questions & Technical Support:

Is the run capacitor included with the motor?
No, this motor requires a 5 MFD / 370 VAC run capacitor, which must be purchased separately to ensure the PSC circuit operates at peak efficiency.

Can I use this as a replacement for a ball bearing motor?
While the Fasco D783 uses sleeve bearings for quieter operation in air-over applications, verify if your specific installation requires ball bearings for high-side axial thrust or specialized orientations.

How do I change the rotation of the motor?
Rotation is easily reversed at the lead end. Ensure all power is disconnected and refer to the wiring diagram on the motor nameplate for specific lead swaps to match the original CW or CCW requirement.
