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 ...

In fact, both capacitors are wired in series with the start winding and in parallel with the run winding. The run capacitor limits the current that will pass through the start winding when the motor ...

Most of these motors use a centrifugal switch to disconnect the start capacitor from the start winding circuit at the time the motor will reach around 70 to 80 of its run speed. The ...

Often, a simple control scheme using a microprocessor can allow manufacturers to use lower starting torque compressors without the use of a hard start kit to operate their ice machines. Before the ...
