Webinar recording

This webinar recording discusses the equalized connections found in an increasing number of factory windings, explains why they are used, and addresses whether or not they are needed when converting a concentric winding to a lap winding. Alternatives, such as changing the number of circuits, or the special extra-long jumpers, are also compared.

Synchronous Reluctance Motor Basics

Article

Advancement in power electronics over the last few decades has made it possible to utilize a variety of rotating electric machines that would otherwise not be feasible. One such class of machines is called reluctance machines because of the way they produce an electromagnetic torque. A reluctance machine is an electric machine in which torque is produced by the tendency of its movable part to move to a position where the inductance of the excited winding is maximized.
