The AC induction motor is often referred to as the workhorse of the industry because it offers users simple, rugged construction, easy maintenance, and cost-effective pricing. These factors have ...

Any electrical motor, from an idealized viewpoint, consists of two sets of magnets—one set stationary, one set free to move—placed in special geometric relation to one another. For most practical ...

This document written by Steve Bowling, Application Segments Engineer at Microchip Technology, discusses how motor works and describes the AC induction motor, variable-speed ACIM control, and FOC.

When powering AC motors, the electrical supply can be at full power to run at full speed or at variable power to run at variable speed. Applications with varying loads benefit from the variable speed ...

AC induction motors are everywhere, from ceiling fans to vehicles. They’re reliable, simple, and rugged — but there are some disadvantages. It’s difficult to control the speed ...

Electric motors consume almost half of the electricity produced worldwide. They, in fact, provide the necessary driving force for much of today’s equipment. Motors, pumps, and fans are present in an ...

You can divide the world of electronic motor drives into two categories: ac and dc. A motor drive controls the speed, torque, direction, and resulting horsepower of a motor. A dc drive typically ...

Before putting an AC machine into service, make sure its duty rating matches the application requirements. Otherwise, there’s a good chance excessive heat will degrade the machine’s windings.

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the ...
