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 ...

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 ...

Many power-consuming devices such as single-phase motors are designed for dual-voltage operation. Figure 1 shows a solenoid valve with four different colored wires coming from its wire housing. Figure ...

A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.

Appliance makers are always looking for quieter, moreefficient motors. Although they've been using singlephase, single-winding, twopole synchronous motors for decades, such motors can be inefficient ...

One of the more popular three-phase electrical services supplied to medium-size commercial buildings is the Wye or Star configuration transformer. The name comes from the transformer’s secondary ...
