An electrical motor comprising a stator 11 equipped with stator terminals 13a,b;14a,b interacting in pairs and provided with windings 15a,b;16a,b and a rotor 12 provided with rotor terminals 17,18 arranged in pairs diametrically opposite the stator terminals and interacting with these. Each rotor terminal 17,18 is provided with a first part 17a,18a which has the same extent around the periphery as the stator terminals 13a,b;14a,b and with a second part 17b,18b which when the first part 17a,18a is directly opposite a stator terminal 13a,b reaches at least as far as to the adjacent stator terminal 14a,b viewed in the direction of rotation. The terminals in the pair of stator terminals are activated alternately so that when one pair of terminals 13a,b is activated the adjacent pair of terminals 14a,b in the direction of rotation is inactivated. The device OP is arranged to detect the voltage which is induced by means of the magnetic flow deflected by the second part 17b,18b of the rotor terminal to the adjacent stator terminal 14a,b. <IMAGE> |
