AC motors are electric motors which are powered by alternating current (AC). They are used to convert electrical energy into mechanical energy in order to do work in a system. Specifically, rotational ...

AC servomotors are AC motors that incorporate encoders are used with controllers for providing feedback and closed-loop control. These motors can be positioned to high accuracy, meaning that they can ...

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 ...

Alternating-current (AC) and direct-current (DC) motors have traditionally served distinctly different applications due to their construction and inherent operating characteristics. In general, AC ...

A Tutorial in AC Induction and Permanent Magnet Synchronous Motors, Vector Control with Digital Signal Processors, Fred Flett, Analog Devices, 1994. This book is an early treatment of AC induction and ...

AC motors are electric motors that run on alternating current (AC), which changes its direction and magnitude periodically. They have two main components: a stator, which is a fixed part that ...

The articles cover traction drives with DC and AC traction motors, electrification systems, and railway signalling and control systems. This first article covers the nature of the traction load, the ...
