ABSTRACT:
A normalization circuit for a phase energization controller receives a rotor position value from a position encoder, and the normalization circuit obtains a normalized rotor position for each phase of a switched reluctance machine. Accordingly, the normalization circuit simplifies the detection of commutation positions for all the machine phases by reducing the commutation position determination to that of a single phase. Also, an initialization circuit for the phase energization controller energizes one or more phases of the switched reluctance motor to set the rotor of the switched reluctance motor to a preferred position to determine an offset value.
