Lennox 43G52 Motor

The Lennox 43G52 Blower Motor is a high-performance PSC (Permanent Split Capacitor) replacement designed for commercial and industrial air handlers. Operating on a single-phase 460V 60Hz electrical supply, this 3/4 HP motor features a three-speed configuration, allowing technicians to fine-tune airflow across diverse system requirements. Built with a standard 48 frame and 1075 RPM rating, the motor provides the necessary torque for heavy-duty air movement while maintaining operational efficiency. The CCWLE (Counter Clockwise Lead End) rotation and sleeve bearing design ensure a direct fit for Lennox OEM specifications, eliminating mounting issues in the field. This direct drive blower motor is commonly utilized in specific Lennox CHA16 and GCS series rooftop units, where balanced performance and long-term durability are critical for maintaining static pressure. Replacing a worn motor with the authentic Lennox 43G52 helps prevent over-amping and ensures the blower assembly operates within the original equipment's design parameters.

• Versatile 3-Speed Control: Provides adjustable airflow options to optimize cooling and heating performance based on specific ductwork resistance.
• NEMA 48 Frame Compatibility: Ensures a seamless drop-in fit for horizontal mounting in compatible Lennox air handlers and furnaces.
• High-Voltage Efficiency: Specifically engineered for 460V single-phase commercial power systems, reducing load stress on electrical components.
• Reliable PSC Design: Utilizes a permanent split capacitor for consistent starting torque and lower energy consumption compared to shaded-pole alternatives.

What is the correct rotation for the Lennox 43G52?
This motor is rated for CCWLE (Counter Clockwise Lead End) rotation. Always verify the rotation of your existing blower wheel before installation to ensure proper airflow direction.

Does this motor include a run capacitor?
Most Lennox 43G52 replacement motors require a separate 20µF 370 VAC or 440 VAC capacitor. We recommend replacing the capacitor whenever you install a new motor to ensure optimal performance.

Can I use this 460V motor on a 230V system?
No, this is a 460V high-voltage motor. Attempting to run this on a 208-230V circuit will cause the motor to fail and may damage your controls.
