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 ...

The Turbolytic50 is a replacement motor-start capacitor-with microfarad ratings from 21 to 324 mfd at 330vac. According the manufacturer, it can replace any one of 50 popular motor start capacitors ...

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 ...

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 ...
