It's just that their speed varies least from no load to full load of all ac-induction motors. Other induction-motor types don't even come close to matching the speed regulation of these motors. Yet, ...

Direct drives place rigorous demands on position-signal quality. Optimum measuring signals increase the quality of the machined workpiece surface, reduce vibration in the machine frame, stop excessive ...

A new magnetic digital encoder featuring 14-bit resolution, differential outputs, and a speed range of up to 200-k e-RPM offers accurate and cost-effective position sensing for various robotic and ...
