Although an increasing interest and use of Permanent Magnet Synchronous Motors (PMSM) can be observed during the last decade, the standard 3-phase Induction Motor (IM) is still the most widely used ...

This solid-state thyristor (SCR) switch circuit is perhaps the simplest means of reversing a 3 phase motor. “Static” is a catch-all term that essentially means without moving (mechanical) contacts ...

Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...

Selection of replacement motors is usually straightforward if the ratings are equivalent. Sometimes, however, a different type of motor is necessary or desirable. For success in these cases, it is ...

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...

Somewhere in most engineering educations, there’s a class on induction motors. Students learn about shaded-pole motors, two-phase and three-phase motors, squirrel cage motors, and DC-excited motors.

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.

In the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...
