Many single-phase motors used on refrigeration systems will incorporate some type of capacitor. They will either use a start capacitor to aid in its starting or a run capacitor to improve its running ...

Back in 2006 I wrote about how my friend Alan Martin over at Texas Instruments had a saying: “It’s always a capacitor.” This was based on his observance that there is a lot of test equipment that goes ...

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 ...

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 QPC series of AC motor run capacitors feature locking push-wire terminals that speed installation and eliminate soldering. A metal mounting bracket also speeds assembly. Standard values range from ...
