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 ...

In low-cost, high-speed motor applications, especially those inside the home, the universal motor dominates. They are as ubiquitous as the countertop blenders and the power tools they inhabit. But not ...

Rodel Vincent Andrada y Corcuera earned a BSc in Electrical Engineering and is currently pursuing an MSc in Electrical Engineering specializing in Instrumentation and Control at the University of the ...

Common to any production operation is movement, usually driven by electric motors. Better control of this movement contributes to improved operational performance. Beyond performance, however, there's ...

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 ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

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 ...

To reap all the benefits that an electric motor drive can offer, choose one that's a perfect match for your application A speed control enables the motor to achieve maximum efficiency during all ...

Indianapolis-Vertical, self-discharging, centrifugal separators must operate at high speeds for separation, then achieve high torque at low speeds for scraping. Classic designs are complicated, ...

In troubleshooting situations involving a motor, more than half the battle is simply isolating the problem. Whenever there’s a working motor, there’s a load and there’s some sort of motor controller, ...

In 1960, the large-angle type PM step motor was the most used step motor. This two-phase, bifilar wound PM step motor (top) advanced 45° mechanical with each pulse from the drive, while by 1962 PM ...

BNSF EMD SD70MAC 9819, one of 450 originally ordered by Burlington Northern in 1993. Wikimedia Commns/ Quatro Valvole. The first locomotive to successfully use an AC (alternating current) three-phase ...
