Lennox 12P50 Motor

As a direct replacement for your equipment, the Lennox 12P50 Motor (also recognized under part number 46132-075) is a high-efficiency 1 HP ECM blower motor designed for precise airflow control in residential and light commercial applications. This 208-230V single-phase unit operates at 600-1200 RPM, utilizing electronically commutated motor technology to deliver constant torque and variable speed performance that outperforms traditional PSC motors. Engineered with a durable 48 frame size and a 1/2 x 3.92-inch shaft, it features a counter-clockwise (CCW) rotation. The internal ball bearings and horizontal belly band mounting ensure quiet, long-term operation even under high static pressure. When swapping out a failed programmed blower motor, this OEM component maintains the original system logic and communication protocols required by Lennox air handlers and furnaces, ensuring proper CFM delivery without needing field-reprogramming of the controller.

• High-Efficiency Variable Speed: Operates between 600-1200 RPM to optimize system static pressure and reduce energy consumption.
• ECM Technology: Integrated variable frequency drive components allow for consistent torque and improved humidity control during cooling cycles.
• Heavy-Duty Construction: Features a rolled steel frame, aluminum flange, and permanent magnets for superior thermal management and durability.
• Drop-In Compatibility: Specifically programmed for Lennox HVAC systems using 7.6 Amp, 208-230V configurations.
• Quiet Operation: Precision-balanced rotor and ball bearing design minimize vibrational noise in the ductwork.

Is the 12P50 a direct replacement for 46132-075?
Yes, the Lennox 12P50 and 46132-075 are identical technical specifications and can be used interchangeably in compatible Lennox blower assemblies.

Can I use this motor in a 115V application?
No, this is a 208-230V 1-phase motor. Attempting to run this unit on 115V will lead to immediate electronic failure of the motor's control module.

Does this motor require a capacitor?
No, as an ECM Blower Motor, the 12P50 manages phase shifting internally through its electronic control module and does not utilize an external run capacitor.
