The Fasco D124 1/50 HP motor is a precision-engineered shaded pole motor designed for continuous duty in air-moving applications. Operating at 115V and 1500 RPM, this 3.3-inch diameter unit is a high-reliability choice for HVAC blower motor replacement. It features a totally enclosed air over (TEAO) enclosure, providing superior protection for internal components in environments where dust or moisture may be present. With a clockwise shaft end rotation and a standard 1/4-inch diameter shaft with a flat, this motor ensures a secure fit with existing fan blades and blower wheels. As a direct replacement for Magnetek U20 and various OEM 3.3-inch frame motors, the Fasco D124 streamlines maintenance for refrigeration evaporator fans and exhaust systems. The motor is thermally protected to prevent overheating during extended cycles and utilizes sleeve bearings for quiet, low-friction operation. Professional contractors prefer this model for its extended stud mounting, which allows for versatile installation across multiple bracket types. This 1500 RPM motor delivers the consistent torque and airflow required to maintain system efficiency in commercial and residential settings. Key Benefits Universal Compatibility: Serves as a rugged drop-in replacement for the Magnetek U20 and other common 3.3-inch frame HVAC motors. Enhanced Durability: The TEAO enclosure and steel frame protect the windings from environmental contaminants in the airflow path. Ease of Installation: Features extended studs on both ends and a 12-inch lead length to accommodate various mounting configurations and belly bands. Quiet Operation: Precision-machined sleeve bearings reduce vibration and noise, essential for indoor air-handling units. Common Questions What is the frame size and mounting pattern for this motor? The D124 features a 3.3-inch diameter frame with a 2-7/8 inch x 2-7/8 inch stud mounting pattern, making it compatible with standard HVAC and refrigeration brackets. Can this motor be used in damp environments? Yes, the totally enclosed air over design protects the motor internals, though it should be positioned in the path of the fan's airflow for proper cooling. Does this motor require a capacitor for startup? No, this is a shaded pole induction motor, which operates without a start or run capacitor, simplifying the electrical circuit and reducing points of failure.
