Lennox 48J10 Motor

The Lennox 48J10 Blower Motor is a high-performance 3/4 HP OEM replacement motor designed for demanding HVACR applications requiring 460V single-phase power. Operating at a synchronous speed of 1075 RPM, this PSC (Permanent Split Capacitor) motor utilizes a 3-speed configuration to allow for precise airflow balancing across diverse static pressure environments. This unit features a 48Y frame with a durable rolled steel housing and aluminum flanges, ensuring structural integrity in horizontal hub ring mounting positions. With a 1/2 x 2.5-inch shaft and CCWOSE rotation (counter-clockwise opposite shaft end), it serves as the direct technical successor to part number 48J1001 and K55HXPHL-5118. This thermally protected motor is engineered for continuous air-over duty, making it a reliable choice for commercial blower assemblies and air handlers where consistent direct-drive motor performance is critical. Professionals should ensure the use of a 20 MFD 370 VAC capacitor to maintain optimal torque and efficiency.

Key Benefits

• OEM Compatibility: Precision-engineered for Lennox HVAC equipment, including Allied, Armstrong, and Ducane commercial air handlers.
• Multi-Speed Flexibility: Features 3-speed taps to optimize system CFM and improve latent heat removal.
• Industrial-Grade Build: Utilizes sleeve bearings and an open enclosure for efficient heat dissipation during peak load cycles.
• Simplified Retrofit: Standardized 48 frame diameter and hub ring mounting reduce installation time for field technicians.

Common Questions

What capacitor is required for the Lennox 48J10?
This motor requires a 20 MFD / 370 VAC run capacitor for proper phase shifting and starting torque. Using an undersized capacitor can lead to overheating and premature failure.

Can I change the rotation of this blower motor?
No, this unit is factory-set for CCWOSE (Counter-Clockwise Opposite Shaft End) rotation. Always verify the rotation of your existing Lennox 48J1001 prior to installation.

Is this motor suitable for 208-230V systems?
No, the Lennox 48J10 is specifically rated for 460V 60Hz operation. Applying lower voltage will result in low torque and potential winding damage.
