Ao Smith 85 Shaded Pole Motor 1/10 Hp 115V 850 Rpm Single Speed

Product Description

The AO Smith 85 is a shaded pole electric motor built for light-duty HVAC and appliance applications. It delivers reliable, consistent performance in systems where a compact, low-horsepower motor is required. HVAC technicians, appliance repair professionals, and equipment installers rely on shaded pole motors like the AO Smith 85 for tasks such as driving small fans, blowers, and other low-torque loads in residential and light commercial equipment.

This motor runs on 115 volts AC at single phase, making it compatible with standard household and light commercial power supplies. It operates at 850 RPM, which is well suited for applications requiring steady, moderate airflow without high speeds. The motor draws 4.0 amps and produces 1/10 horsepower, placing it in the category of small fractional horsepower motors used throughout the HVAC and appliance industries.

The AO Smith 85 features a 4.3 frame size, which is a common compact form factor found in OEM equipment. The open air enclosure allows for natural ventilation and cooling during operation. A sleeve bearing design reduces friction and provides quiet, smooth operation over extended run times. The shaft measures 3/8 inches in diameter and 2 1/2 inches in length, with a counterclockwise rotation when viewed from the shaft end. This CCW rotation is a critical spec when selecting a replacement motor to ensure proper fan or blower direction.

Shaded pole motors are known for their simple construction, low cost, and long service life in applications with low starting torque requirements. The AO Smith 85 is a direct replacement option for OEM motors with matching electrical and mechanical specifications. Always verify frame size, shaft dimensions, voltage, RPM, and rotation direction before installation.
