摘要:
Certain circuit faults in a phase of a multi-pole, switched reluctance, rotary electrical machine are detected; and the machine is selectively operated with a detected circuit fault when the nature of the fault permits continued operation of the phase and the operation of the phase is desirable. The fault may be one of certain short or open circuits in which at least one of the two current controlling electronic switches is operable to control phase current within predetermined limits. In the continued operation when a fault is detected, (1) the phase current is switched off earlier than it would be in the absence of the fault and/or (2) the maximum phase current is reduced compared with that permitted in the absence of the fault; and either or both of these modifications may be a function of motor speed. If the circuit fault adversely affects current control by an electronic switch normally controlling current level, another electronic switch is substituted for current control.
