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 ...

Linear motors are generally classified by the construction of the motor’s primary part: ironless or iron core. In an ironless linear motor, the windings of the primary are embedded in an epoxy resin, ...

Ironless linear motors have had a clear advantage over ironcore linear motors in many applications for one clear reason: they’re not subject to cogging. “Cogging” is a term used to describe ...

The highly dynamic AL8000 linear motors from Beckhoff now meet even greater requirements for accuracy and synchronization with the new TwinCAT Cogging Compensation software. This makes the linear ...

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 ...

Beckhoff’s AL8000 linear motors can now deliver greater accuracy and synchronization with the company’s new TwinCAT Cogging Compensation software. According to Beckhoff, this software enables linear ...

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.
