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 ...

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 ...

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 ...

Choosing the right motor and VFD type depends on a variety of factors, however, it is necessary to first look at how the characteristics of a motor change when the speed is reduced —Sponsored article ...

This application note presents space vector modulation, a technique that can be applied for AC inductor motors and 3-phae BLDC motor types. It demonstrates how Zilog’s Z16FMC MCU can implement ...

This article discusses the evaluation of a small 0.75 hp, 4-pole, 460 V, AC induction motor. The original insulation system of the motor was a typical Class 155C (Class F) material with a Class F lead ...

Permanent magnet DC (PMDC) motors offer smaller solution size and increased efficiency in applications such as portable vacuums and cordless electric power tools. When designing an isolated power ...
