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 ...

Troubleshooting single-phase refrigeration compressors requires a technician to have a proficient understanding of capacitors. The start capacitor is one of two types of capacitors that can be found ...

As an electric motor’s rotor turns in close proximity to the motor windings, a bucking voltage or back electromotive force (EMF) is generated. The back EMF (BEMF) generated across the start winding is ...

The PSC motor uses a capacitor and has good running efficiency. When a PSC motor is used in compressors, it makes use of two capacitors attached to its wiring. The first one serves as a start ...
