<p>A reluctance motor comprises a stator having two diametrically opposed poles, and windings, and a rotor of soft magnetic material, having two correspondingly positioned poles, each rotor pole having a portion with a peripheral extension which coincides with the corresponding extension of the respective stator pole, and an additional portion adjacent the first-mentioned portion, and having a pole surface which is situated closer to the shaft of the rotor than the first-mentioned portion. A device is arranged during the starting process of the motor to drive the motor by current pulses of a magnitude which in areas of pole overlap brings at least those portions of the stator and the rotor pole, respectively, which are situated closest to the pole surfaces to saturation.</p> |
