Abstract:
Provided is a method of indirect position estimation in three-phase switched reluctance machines. The method may comprise providing a three-phase switched reluctance machine. A three-phase switched reluctance machine may comprise a rotor and three phases. The method may further comprise producing data about the machine, setting threshold current values for at least a first phase; and sensing rotor position. Sensing rotor position may comprise applying a sensing pulse voltage sufficient to induce a pulse current having some maximum amperage in the first phase, determining the amplitude of the maximum amperage of said pulse current with respect to the thresholds for the first phase, and determining the sector of the rotor based upon the amplitude of the maximum amperage of the pulse current in the first phase.
