Carrier HD56FR652 Blower Motor

The Carrier HD56FR652 Blower Motor is a high-performance 1.5 HP OEM replacement motor engineered for demanding commercial HVAC and industrial applications. Built for constant air-over (CAO) duty, this three-phase blower motor operates at 208-230/460V and a fixed speed of 1725 RPM. Housed in a durable 56Y frame, it features a rolled steel body and aluminum flange to provide superior structural integrity and corrosion resistance in light commercial environments. This motor utilizes permanently lubricated ball bearings to minimize mechanical friction and ensure a longer service life without the need for periodic re-greasing.

For technicians performing a field swap, the HD56FR652 features a 5/8-inch keyed shaft and a welded bolt mounting configuration for a secure fit within the blower housing. Its Class B insulation and NEMA Design B rating signify it can handle the thermal demands of horizontal or vertical forced-air systems found in heat pumps and gas furnaces. This factory authorized part is the primary replacement for older Marathon Electric model 5K49MN4735X, ensuring electrical and physical compatibility without the need for extensive ductwork or bracket modifications.
