Cheap, brushless motors may be the workhorses behind our RC planes and quadcopters these days, but we’ve never seen them in any application that requires low-speed precision. Why? Sadly, cheap ...

An adaptive algorithm kills jerky motions in motors. High-performance motion-control applications commonly use three-phase permanent-magnet synchronous motors, popularly known as brushless motors.

Almost two years ago, a research team showed that it was possible to get fine motor control from cheap, brushless DC motors. Normally this is not feasible because the motors are built-in such a way ...

Slotted linear motors move with speed and precision, and are raising the bar on linear motion applications. They consist basically of magnets and windings. The magnets bond to an iron plate, forming a ...
