Which type of motor is typically used on condenser and evaporator motors?

Squirrel cage motors are commonly used for condenser and evaporator applications due to their robust construction and efficiency in continuous operation. These motors are a type of induction motor and are especially suitable for HVAC applications because they can handle varying loads and are designed for high torque at startup. Their simple design, featuring a rotor that consists of conductive bars shorted at both ends, allows for effective cooling and operation under the diverse conditions found in refrigeration systems.

Additionally, squirrel cage motors have excellent speed regulation and are capable of operating in harsh environments typical in HVAC settings, where they may be exposed to moisture and other contaminants. This makes them reliable choices for both condenser and evaporator functions, which require consistent performance for effective heat exchange processes. The design also minimizes maintenance needs, making it ideal for long-term use in refrigeration systems.
