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 ...

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 ...

Scientists are working to create electronics capabilities for electric vehicles, with the development of a high temperature capacitor. Scientists at the National Physical Laboratory are helping to ...
