Capacitor Testing for Electric Motors | EC&M
Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical components for electric motors in general, as well as for specific use applications like motor starting and PF correction (see Photo 1 and Photo 2 ).
Why is a Capacitor Needed for a Single-Phase Motor?
Without a capacitor, the motor will lack the necessary phase shift to create a rotating magnetic field. As a result, the motor will either not start at all or will start slowly and with reduced torque. This can cause the motor to overheat and eventually fail.
