Abstract

The invention relates to a reluctance motor (1) having a rotor (3) and a stator (2). The stator (2) has individual stator coils (6), and a predefined current (I) flows in one of the coils (6), in accordance with the engine (1) load. The invention aims to achieve adequate precision in determining the rotor position with simple and inexpensive measuring methods. To this end, the predefined current (I) is obtained by applying a constant voltage (U), and the time (t1, t2) necessary to reach the maximum current value (I Max) when applying this constant voltage (U) is measured, giving the value of the engine (1) load.
