Ao Smith opv748 Psc Motor 1/6 1/12 1/20 Hp 115V 3 Speed

Product Description

The AO SMITH opv748 is a multi-horsepower PSC (Permanent Split Capacitor) motor rated for 115 volts and three selectable speeds. It covers a horsepower range of 1/6, 1/12, and 1/20 HP, giving technicians flexibility across a variety of light-duty HVAC and ventilation applications. PSC motors are the standard motor type in residential and light-commercial air handlers, furnace blowers, and evaporator fan assemblies. Licensed HVAC technicians and motor replacement specialists are the primary installers of this unit.

This motor is suited for residential and light-commercial installations where a single replacement part must cover multiple HP configurations. The three-speed capability allows the motor to serve different airflow demands within compatible blower and fan assemblies. It operates on standard 115-volt single-phase power, making it a practical stocking item for service trucks and shop inventory where a range of motor HP ratings is needed on a single call.

Key Features

• Three selectable speeds support varied airflow configurations in a single motor
• Multi-horsepower rating (1/6, 1/12, 1/20 HP) reduces the number of SKUs a technician must carry
• PSC design delivers reliable, low-maintenance operation in continuous-duty HVAC applications
• 115-volt single-phase input matches the most common residential and light-commercial power supply

Compatibility

Designed as an OEM-style replacement PSC motor for residential and light-commercial HVAC blower and fan applications requiring a 115-volt, 3-speed motor in the 1/20 to 1/6 HP range.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all electrical power to the equipment before removing the existing motor or making any wiring connections. Verify that the mounting configuration, shaft size, and rotation direction of the replacement motor match the original unit before final installation. Refer to the equipment manufacturer wiring diagram and applicable NEC requirements when terminating motor leads.
