Heil Quaker ICP 1176645 Motor

The Heil Quaker ICP 1176645 Motor is a heavy-duty, three-phase blower motor engineered for high-static pressure applications in commercial HVAC systems. Operating at 5 1/4 HP with a dual-voltage range of 208-230/460Vac, this 1740 RPM power plant is designed for continuous duty cycles. Built on a 145TY NEMA frame size, it features a rigid mount and reversible rotation capabilities, providing the versatility required for diverse field configurations. The ball bearing construction ensures minimal friction and handles high temperatures better than sleeve-bearing alternatives, extending the service life of the OEM replacement motor in demanding environments. Drawing 15-7.4 Amps, this single-speed unit delivers consistent torque to the blower wheel, maintaining critical airflow across the heat exchanger or cooling coils. When sourcing ICP replacement parts, verifying the 145TY frame and shaft diameter is essential for ensuring a drop-in fit without field modifications to the mounting bracket.

Key Benefits

• Industrial Durability: The ball bearing design supports axial and radial loads, ensuring reliable performance in belt-drive or direct-drive blower assemblies.
• Field Versatility: Reversible rotation allows for easy adaptation to clockwise or counter-clockwise requirements during installation.
• Efficient Power Delivery: The three-phase 208-230/460V configuration provides high starting torque and smoother operation compared to single-phase motors.
• Rigid Mounting: The 145TY NEMA frame with a solid base ensures a stable, vibration-free installation to protect the drive train.

Common Questions

Is the Heil Quaker 1176645 a direct replacement for 5HP motors?
This specific motor is rated at 5 1/4 HP. While it can often replace a standard 5HP 145T frame motor, always verify the 145TY frame dimensions and amperage draw to ensure your motor starter and overloads are correctly sized.

Can this motor be used with a Variable Frequency Drive (VFD)?
As a three-phase motor, it is compatible with most VFDs used in commercial air handlers, though technicians should verify the insulation class for high-frequency switching environments.

How do I change the rotation direction on this unit?
Since this is a three-phase motor, rotation is reversed by swapping any two of the three power leads at the terminal box or motor starter.
