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, ...

Single-phase motors are common in many industries and can be found in blowers, pumps, fans, lathes, and numerous other types of equipment. Single-phase motor failures or malfunctions can often be ...

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 ...
