A brushless D-C motor of the type having a permanent magnet rotor, a plurality of individual stator windings which are disposed 90 DEG apart with respect to each other, and at least two Hall-effect galvanomagnetic transducers which are disposed 90 DEG apart with respect to each other, and within the air gap of the motor. The galvanomagnetic transducers produce control signals in response to the angular position of the rotor for controlling the conductive states of semiconductive switching devices which are each electrically disposed in series with respective individual stator windings, and a controlled current generator which controls the current flowing through the stator windings so as to conform with a sinusoidal wave shape. |
