FAULT MANAGEMENT SYSTEM FOR A SWITCHED RELUCTANCE MOTOR

摘要

RD-18,894 FAULT MANAGEMENT SYSTEM FOR A SWITCHED RELUCTANCE MOTOR A fault management system for a switched reluctance motor detects faults through phase current differential sensing and phase flux differential sensing and isolates any fault by deactivating any faulted phase. Motor operation continues through the remaining phases. A speed control circuit maintains the normal operating speed of the motor, despite the deactivation of one or more phases. Starting the motor when stopped in a "dead zone" created by a faulted phase is accomplished by using the intact phases to generate negative torque to move the rotor out of the dead zone.
