Basic thermodynamic laws tell us that, no matter what its design, in every electric motor some of the input electrical power is undoubtedly lost (via heat) as it is converted to output moving power.

Stepper motors are well known for their ability to perform accurate positioning in an open-loop mode. But they have a reputation for generating a lot of heat when rotating at high speeds. Generation ...

A new stepmotor design boosts efficiency and reduces noise and vibration. Most engineers are familiar with hybrid stepmotors. But inside the apparently simple mechanism rests a complex combination of ...
