Mating a non-cogging motor with an ultra-precision air-bearing spindle enabled a micro-grinder spindle/indexing system for outside diameter (OD) grinding and profiling of parts with diameters as small ...

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 ...

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.
