Every day engineers design products that employ single-phase induction motors. Speed control of single-phase induction motors is desirable in most motor control applications since it not only provides ...

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 ...

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

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, ...

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 ...

When electric motors are installed in wet or damp areas, their lives are inevitably shorter than if they lived in a dry climate. However, using a little caution can extend motor life. Open Drip Proof ...
