Carrier CFM3166A Motor

The Carrier CFM3166A Motor is a heavy-duty, 3-phase replacement engineered for high-demand industrial and commercial condenser fan applications. Operating at 1.5 HP and a synchronous speed of 1140 RPM, this motor provides the reliable torque required for large-scale air-over (OAO) cooling systems. Built by Baldor-Reliance for Carrier, it features a 56YZ frame with a belly band mount, ensuring compatibility with a wide range of Carrier, Bryant, and Payne units. The 208-230/460V multi-voltage rating allows for flexible field wiring in various power configurations.

For technicians in the field, the CFM3166A HVAC motor is designed for longevity and ease of maintenance. It includes ball bearings and a 6-inch long shaft with a keyway and flat oriented at 90 degrees for secure blade attachment. This 3-phase condenser fan motor is dynamically balanced to reduce vibration and noise, maintaining unit efficiency during continuous duty cycles. Ensure you verify the mounting spacing and amperage draws against the existing 1.5 HP 1140 RPM motor to ensure a proper drop-in fit.

Key Benefits

• Multi-Voltage Compatibility: Operates on 208-230/460V 3Ph, making it a versatile choice for commercial electrical services.
• Durable Construction: Features lubed-for-life ball bearings and a corrosion-resistant finish for extended service in outdoor environments.
• Optimized Performance: Specifically designed for open air-over (OAO) cooling to prevent overheating during high-ambient operation.
• Secure Mounting: The 56YZ frame is optimized for belly band or band mount installations common in industrial condensers.

Common Questions

What are the rotation and wiring requirements for this motor?
The Carrier CFM3166A is a three-phase motor; rotation can be easily reversed by swapping any two power leads. It utilizes reconnectable leads in the pulley endplate for standard terminal panel connectivity.

Is this a direct replacement for 1.5 HP 1200 RPM motors?
Yes, in most 1200 RPM synchronous speed applications, this 1140 RPM motor serves as the standard industrial replacement, provided the frame size and mounting match.

Can this motor be mounted in any orientation?
This motor is designed for air-over applications. While the configuration is standard for belly bands, always ensure the water slinger is positioned correctly to protect the bearings from moisture ingress.
