What type of torque does a PSC motor primarily produce when starting?

A permanent split capacitor (PSC) motor primarily produces low starting torque when it begins to operate. This characteristic is due to its design, which includes a single winding and a capacitor that aids in the starting phase but does not provide significant additional torque. The low starting torque is suitable for applications where the load is light or does not require a high initial force to start moving.

In contrast, applications that necessitate higher starting torque typically utilize different types of motors, such as split-phase or capacitor start motors, which generate more starting torque due to their winding configurations and additional components designed to maximize initial force. This is important to remember as it highlights the specific capabilities and limitations of PSC motors in various operational contexts. Understanding the torque characteristics helps those in the field make informed choices regarding motor selection for specific applications based on load requirements.
