Rectorseal M20538 Direct Drive Motor 1/2 Hp 460V

Product Description

The RECTORSEAL M20538 is a direct drive electric motor rated at 1/2 horsepower and 1,075 RPM, operating on 460 volts. Direct drive motors eliminate the need for belts and pulleys, reducing maintenance and mechanical losses. This unit is designed for use in HVAC air handling equipment where the motor couples directly to the blower wheel. Licensed HVAC technicians and mechanical contractors handle installation of this type of motor in commercial and light commercial applications where 460-volt three-phase or single-phase power is standard.

The M20538 is suited for direct drive blower and fan applications in air handling units, fan coils, and similar HVAC equipment operating on 460-volt electrical systems. This motor is a practical replacement option when the original direct drive motor has failed or reached end of service life. Its 1,075 RPM speed rating is common in condenser fan and evaporator blower assemblies that require lower operating speeds for airflow control.

Key Features

• 1/2 HP output rating for direct drive blower and fan loads
• 1,075 RPM operating speed for controlled airflow applications
• 460-volt rated for commercial and light commercial electrical systems
