    摘要: Gegenstand der Erfindung ist ein Verfahren zum Ansteuern eines Reluktanzmotors, mit Leistungsschaltern in den Stufen niedrigen und hohen Potentials der Motorstränge, wobei im Hochpotentialzweig nur ein Leistungsschalter vorgesehen ist.
    Sie besteht darin, daß von den drei Strängen R, S, T ein Strang (R, S, T) vollständig abkommutiert, d. h. der Strom auf Null abgebaut wird, bevor der nächste Strang (R, S, T) bestromt, d. h. aufkommutiert wird und daß der Schalter (T S , T T , T R ), der den Kommutierungsvorgang bewirkt, vor dem Einleiten des Kommutierungsvorgangs von einem Strang (R, S, T) auf den nächsten Strang (S, T, R) vorzeitig geschlossen wird.

    摘要: A drive control method for a variable reluctance type motor enabling the prevention of the generation of a disturbance torque and the improvement of the efficiency of the motor. In function generators (8A-8C) of the control equipment where the method is adopted, the rotational direction and operation mode of the motor are determined, based on the order of the generations of A-phase and B-phase feedback pulses fed from a pulse coder (7) and the sign of a torque command (Tc) fed from a velocity loop compensating circuit (1) and one of four current application patterns is selected in accordance with the result of the determination. According to the selected pattern, function signal values corresponding to a real electrical angle (Θ) of the motor are sent from the function generators and current application to the respective phases of the motor (6) are controlled by power amplifiers (4A-4C) responding to the voltage commands derived from the function signal value. The current application stopping time is so set as to eliminate a winding current before a disturbance torque is generated by the current flowing through the stator winding which is caused owing to the inductance of the stator winding after the current application stopping. Thereby, the generation of the substantial disturbance torque is prevented.

    摘要: A switched reluctance motor has its stator poles divided into at least three phases, each phase having its own independently switchable phase windings wound around the corresponding stator poles. First switch elements control application of power to the windings of the first phase, second switch elements control application of power to the windings of the second phase, and third switch elements control application of power to the windings of the third phase. For low speed operation of the motor, the switch elements for each phase are controlled to apply power to its respective phase windings from a selected turn-on angle to a selected turn-off angle. The maximum difference in low speed operation between the turn-on angle and the turn-off angle for each phase is no greater than the angle sub­tended by adjacent stator poles as measured from the geometric center of the stator. For high speed operation, only the windings of the first phase are energized, and the difference between the turn-on angle and the turn-­off angle for the first phase windings is greater than the angle subtended by adjacent stator poles.

    摘要: In a power supply system for a variable reluctance motor, each phase winding (a, b) of the motor is connectible across a pair of supply rails by first (GTO a , GTO b ) and second (T a T e ) switch means located respectively between the first supply rail and the winding and between the winding and the second supply rail. The first switch means (GTO., GTO b ) is a fast switch-off device such as a gate tum-off thyristor or a transistor, while the second switch means (T a , T b ) is a slow turn-off device, such as a thyristor suitable for application to a line-commutation situation. In a two-phase configuration, where the second switch means is a thyristor, force- commutation of the second switch means may be achieved by means of a suitable capacitor (C c ) interconnection between the thyristors switching the respective phases.

    摘要: An excitation circuit for a flux switching motor. The circuit includes a low-value film capacitor across the DC side of a bridge rectifier. A plurality electronic switches are arranged in an H-bridge configuration for switching current flow through an armature winding of the motor in accordance with a PWM control scheme and single-pulse control scheme controlled by a microcontroller. A start-up diode is placed across the field winding of the motor and is electronically switched out of the circuit after a startup phase of the motor has completed. The circuit implements armature energy recirculation through the field winding during startup to promote more uniform and quicker startup of the motor. The use of a film capacitor improves the power factor of the circuit, helps to eliminate the introduction of harmonics into the AC voltage source, and helps in mitigating EMI. Reverse commutation is used to bring the motor to a quick stop when it is powered off.

    摘要: An electrical machine, such as a switched reluctance motor (7), has a rotor and at least one electrically energisable phase winding. A control map is derived during production, comprising a predetermined advance angle profile representing energisation of the phase winding with respect to angular position of the rotor over a range of rotor speeds. This is stored in memory in a controller (9), together with an angle correction factor to be applied to a predetermined portion of the advance angle profile. The angle correction factor compensates for the difference between a desired input power and the measured input power. The correction factor may be transmitted to the controller by means of radio frequency signals.
