SWITCHED RELUCTANCE MOTOR DRIVE SYSTEM AND LAUNDERING APPARATUS EMPLOYING SAME Abstract of the Invention A microcomputer-based drive system for a switched reluctance motor requires no rotor position sensor and no discrete current sensors. Phase excitation is synchronized with rotor position by indirectly estimating rotor position according to instantaneous phase inductance. Current regulation is achieved by incorporating pilot devices for current sensing into the switching devices of the power converter and by employing a fixed off-time current chopping strategy. One application is for use in a laundering machine.
