Abstract

A reluctance motor comprises a stator (10) having poles (11, 12, 13, 14), co-operating in pairs, disposed in diametrically opposite positions and provided with windings (15a, b; 16a, b), and a rotor (17), made of soft-magnetic material and having poles (19a, b; 20a, b), co-operating with the stator poles and disposed in pairs in diametrically opposite positions. In each stator pole pair (11, 12; 13, 14) the windings (15a, b; 16a, b) are connectable to a source of DC voltage via two separately controllable switches (T1, T2) such that one switch (T1) connects the windings to the positive terminal of said source while the other switch (T2) connects the windings to the negative terminal of said source. Two free-wheeling diodes (D1, D2) are provided to co-operate with the respective switch in order to permit a continuous flow of current through the windings when the switch opens. Control means (54, 36, 38, 39, 40, 44, 45) are provided to emit control signals to the switches (T1, T2) to turn them on and off. The control means have a design such that the switches mainly simultaneously receive a control signal (TR1, TR2) closing the same, while at turn-off the corresponding control signals (TR1, TR2) are supplied to the switches at different times.
