Find a downloadable version of this story in pdf format at the end of the story. Microstepping a two-phase stepper motor requires the winding currents to be 90° out-of- phase so that the stepper ...

A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.

What if one innovation could redefine how industries consume energy, slashing waste and environmental impact while saving millions? Enter ABB’s new brushless synchronous motor, a technological marvel ...

This advanced variant of a separately excited synchronous motor is thus an alternative to permanent-magnet synchronous machines (PSM). New Delhi: ZF has developed an electric motor which does not ...

German tier 1 supplier ZF has developed an electric motor which does not require magnets. The company says in contrast to the magnet-free concepts of so-called separately excited synchronous motors ...
