The two most important electric motors are the ac induction motor and the permanent magnet (PM) brushless synchronous motor, also known as the brushless dc or ac servo motor. These motors have ...

Combining the advantages of permanent magnet and induction motors, new synchronous reluctance motors (SynRM) offer potentially breakthrough technology for variable speed drive (VSD) and motor packages ...

Geothermal power offers a stable, continuous source of renewable energy that could help power millions of homes while reducing dependence on fossil fuels. As governments worldwide pursue ...

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 ...

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 ...

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.

The joint venture Astemo, a collaboration between Hitachi and Honda, has developed a new motor for battery-electric vehicles ...

The basic operating principles of SynRM machines. The advantages SynRM machines offer over switched reluctance motors. How the latest advances in SynRM design are steadily improving the motors’ ...

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 ...

New and increasingly stringent efficiency standards have made motor efficiency a priority among motor manufacturers and designers of motor-driven systems. While the Energy Independence and Security ...
