A squirrel cage induction motor must sense two or more electric phases to cause the magnetic field to start spinning, thus turning the motor’s rotor and shaft. Once the motor starts, the interaction ...

Potential relays are commonly found on many smaller, single-phase, capacitor-start, capacitor-run motors in the HVACR industry. Their function is to assist in starting the electric motor. Potential ...

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 ...
