Rotor for a switched reluctance machine

摘要

A rotor for a switched reluctance machine has its main magnetic circuit provided by two mouldings of soft magnetic composite. The mouldings are substantially identical and fit together to form a magnetic circuit which, by virtue of its design, has a very low inductance in the unaligned position. The portions of the magnetic circuit lie beyond the active length of the rotor poles and the flux path is described in three dimensions.
