Heil Quaker ICP 1070646 Motor

The Heil Quaker ICP 1070646 is a heavy-duty 3 HP blower motor engineered for high-static pressure applications in commercial HVACR systems. This industrial three-phase motor operates on a dual-voltage 208-230/460V platform, drawing 9.0-9.2/4.6 Amps at a synchronous speed of 1750 RPM. Built on a 56 NEMA frame with a rigid base, this unit utilizes ball bearing construction to minimize friction and extend the operational life of the internal windings. Designed for versatility, it features reversible rotation, making it a critical ICP motor replacement for various air handler and rooftop unit configurations. The single-speed design ensures stable performance across the fan curve, providing the torque necessary for large-diameter blower wheels. For technicians performing a Heil blower motor repair, this motor provides the mechanical durability required to maintain system airflow requirements in demanding environments without the risk of premature failure from thermal overload under standard operating conditions.

Key Performance Benefits

• Versatile Voltage Support: Compatible with 208-230V and 460V three-phase power supplies for broad site application.
• Rugged NEMA 56 Frame: Rigid mount design ensures precise shaft alignment and reduces vibration in high-velocity blowers.
• Field-Reversible Rotation: Simplifies installation by allowing the technician to match the specific rotation of the existing blower housing.
• Low Maintenance Internals: Permanently lubricated ball bearings handle higher radial and axial loads than sleeve bearing alternatives.

Common Technical Questions

What is the frame size and mounting style for the 1070646?
This motor utilizes a standard 56 NEMA frame with a rigid base, ensuring it fits standard mounting brackets found in Heil and Quaker commercial air handlers.

Can this motor be used with a Variable Frequency Drive (VFD)?
While this is a single-speed three-phase motor, ensure your VFD is rated for 3 HP and follows proper grounding and cabling practices to avoid shaft voltage issues.

How do I change the rotation on this blower motor?
Rotation is reversible by swapping any two of the three primary power leads at the motor terminal box or the contactor.
