FIGURE 1: This electrical schematic diagram shows the cooler’s single-phase, R-134a capacitor start/capacitor run (CSCR) refrigeration compressor motor, and starting relay circuit section. July 6, ...
A popular style of fan motor used on older refrigeration equipment is the permanent split capacitor (PSC) motor. It is an electric motor made up of essentially two magnets: one is stationary (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 ...
