Rectorseal M10689 Direct Drive Blower Motor 3/4 Hp 115V

Product Description

The RECTORSEAL M10689 is a direct drive blower motor rated at 3/4 horsepower and 115 volts, designed for continuous-duty air handler and furnace blower applications. It runs on a single-phase PSC (Permanent Split Capacitor) motor design with a 6-pole configuration, delivering a nominal speed of 1075 RPM across an operating range of 925 to 1200 RPM. The motor features automatic thermal protection and an open air over (OAO) enclosure, making it suited for airstream-cooled blower wheel installations. Licensed HVAC technicians and air handler service techs are the primary installers of this motor type.

This motor is built for direct drive blower applications in residential and light commercial HVAC systems, including forced-air furnaces and air handlers where the motor shaft couples directly to the blower wheel without a belt or pulley. The T-FLEX designation indicates a flexible frame design that accommodates a range of mounting configurations. With three speed taps and reverse rotation, it supports systems requiring airflow adjustment or directional airflow configurations common in multi-speed air handler setups.

Key Features

• 3/4 HP continuous-duty rating for sustained blower operation
• PSC motor type for efficient single-phase operation
• Three speed taps allow airflow adjustment without additional components
• Reverse (REV) rotation for correct airflow direction in direct drive installations
• Automatic thermal protection guards against overheating during extended run cycles
• OAO enclosure relies on airstream cooling, standard for blower compartment mounting
• RPM range of 925 to 1200 supports variable-load blower applications

Compatibility

Designed as an OEM-style direct drive replacement motor for residential and light commercial forced-air furnace and air handler blower assemblies requiring a 3/4 HP, 115V, single-phase, 3-speed PSC motor with reverse rotation.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all electrical power to the air handler or furnace before removing the existing motor. Verify that the replacement motor shaft diameter, length, and rotation direction match the existing blower wheel and housing before final mounting. Wiring should comply with NEC requirements and the equipment manufacturer's wiring diagram.
