Regal Beloit 645 Blower Motor 1/3 Hp 1120 Rpm 5.6 Amp 230V Ccwse 1/2 Inch Shaft

Product Description

The Regal Beloit 645 is a 1/3 horsepower blower motor built for residential and light commercial HVAC applications. It runs at 1120 RPM and draws 5.6 amps at 230 volts. The motor features a counter-clockwise shaft end (CCWSE) rotation and a 1/2 inch shaft for direct connection to blower wheels and fan assemblies. HVAC technicians use this motor as a direct replacement in forced-air furnaces, air handlers, and evaporator coil blower assemblies. The 230-volt single-phase design is common in many residential split systems and packaged units. Running at 1120 RPM, this motor moves air at a steady, controlled speed suited for indoor blower applications where quiet operation and consistent airflow matter. The 1/3 HP output delivers enough torque to drive standard squirrel-cage blower wheels without overloading the motor or drawing excessive current. The CCWSE shaft orientation is critical for matching the correct rotation to the blower housing. Installing the wrong rotation direction can reduce airflow performance significantly. Regal Beloit is a well-known manufacturer of fractional horsepower motors used across the HVAC, refrigeration, and air movement industries. Technicians rely on Regal Beloit motors for their consistent build quality and compatibility with OEM blower assemblies. This motor ships as a single unit and is ready for field installation. It is well suited for service technicians stocking replacement motors for common residential HVAC equipment. Confirm shaft diameter, rotation, voltage, amperage, and RPM against the existing motor nameplate before installation to ensure proper fit and performance.
