It used to be a staple of junior high physics class to build some sort of motor with paperclips or wire. A coil creates a magnetic field that makes the rotor move. In the process of moving, brushes ...

Linear motors are becoming increasingly practical for general motion. Many are used for long strokes of a few feet or more. One new design, however, where the magnets move relative to a stationary ...

The electric vehicle revolution has created market forces to drive all sorts of innovations. Battery technology has ...

Continuing headlines about superefficient electric drives might lead some observers to wonder about the future of three-phase induction motors. The truth is that induction motors aren’t going away any ...

DETROIT (AP) — General Motors has taken two more steps to make sure it has the raw materials for the transition from petroleum to battery power, this time lining up magnets for electric vehicle motors ...
