Abstract: A switched reluctance motor drive system (10) with phase windings (12) and commutator switches (21-23) is provided with a setting device (15) for operating the commutator switches (21-23). In a first condition the setting device (15) operates the switches (21-23) to provide the respective windings (12) with sequentially-occurring conduction periods for normal running of the system (10). In a second condition the setting device (15) operates the switches (21-23) to provide the respective windings (12) with simultaneously occurring conduction periods for braking or hold still of the system (10).

Abstract: A switched reluctance motor (10) has a rotor position sensing system (22) to provide for each rotor revolution one set of logic state transitions having time intervals and time durations determined by the angular rotor position with respect to a datum. The output from system (22) is delivered to a logic circuit device (24) with several channels and arranged to derive further sets of logic transitions by combinatorial logic. One set of logic transitions is selected by a selector (25) and is applied to the commutation switches of the motor (10).

Abstract: A switched reluctance motor is controlled by a control system (10) which has only a single chopper switch (12) for all of the phaselegs (A, B, C) which are connected in parallel with a freewheeling diode (19). Each phaseleg (A, B, C) has terminals (13, 14) for connection to a respective motor winding and a commutator switch (15). The various commutator switches (15) are operated sequentially by an arrangement (21) so that the d.c. power supply V is switched sequentially from one phaseleg to another. Recovery of enegy stored in each phaseleg (A, B, C) at the end of its conduction period is achieved without the requirement of an energy storage capacitor by an energy recovery diode (18) connected between terminal (14) and the d.c. supply V.
