LEESON 111954.00 Motor
The LEESON 111954.00 Motor is a high-performance 3/4 HP HVAC motor engineered for demanding air-moving applications. This 115V single-phase motor operates at a base speed of 1800 RPM and features a two-speed, variable torque design (1725/1140 RPM), making it ideal for belted fans or fan-on-shaft configurations. Built with a durable rolled steel frame and a NEMA 56H frame size, it includes a 5/8-inch keyed shaft and a resilient base to minimize vibration and noise during operation. The Open Drip Proof (ODP) enclosure allows for effective self-ventilation, whether mounted within or outside the fan's airstream. This capacitor start motor is designed for continuous duty, utilizing high-quality ball bearings to ensure reliable rotation and long-term service in commercial or residential HVAC systems. Its selective CCW rotation and 1.0 service factor provide the precise performance required by professional contractors for mission-critical ventilation equipment.
Key Benefits- Enhanced Stability: The resilient mount design absorbs operational vibration, extending the life of both the motor and the connected blower assembly.
- Versatile Two-Speed Operation: Optimized for variable torque, allowing for efficient 1725/1140 RPM switching to match system demand.
- Heavy-Duty Construction: Features a NEMA 56H frame with a 5/8" keyed shaft and ball bearings for robust mechanical support.
- Optimized Airflow: The ODP enclosure is specifically rated for HVAC/R applications, ensuring the motor stays cool under continuous load.
Can this motor be used in a direct-drive application?
Yes, the LEESON 111954.00 is suitable for both belted and fan-on-shaft (direct drive) applications, provided the load remains within the variable torque parameters.
What is the difference between a 56 and a 56H frame?
The 56H frame is a combination base that includes mounting holes for both NEMA 56 and NEMA 143-5T configurations, offering greater flexibility for replacement in existing brackets.
How do I reverse the rotation on this unit?
The motor is shipped with selective CCW rotation from the factory. To adjust rotation, refer to the wiring diagram located on the nameplate, as lead changes are required.
