ABSTRACT:
A switched reluctance motor includes an auxiliary winding interspersed among the main phase windings such that a constant inductance ratio is established between the main and auxiliary windings regardless of rotor position. The auxiliary winding preferably has a higher inductance compared to the main winding. A test current is injected into the auxiliary winding in order to indirectly determine rotor position and the auxiliary winding is utilized to maintain a holding torque under static load conditions. The disclosed design and methodology improves motor function capabilities and economies.
