Title (EN) DIRECT CURRENT MOTOR WITHOUT COLLECTOR
(FR) MOTEUR A COURANT CONTINU SANS COLLECTEUR
Abstract: front page image
(EN)In a direct current motor without collector provided with a permanent magnet rotor (11), a magnetisation of the rotoric poles (N, S) is used which differs considerably from the sinusoidal form. In addition to the main winding (35-47) used for driving the motor, the stator is further provided with a detection winding (80) arranged so as to detect a harmonic of the voltage induced in the stator by the rotoric poles (11), for example the second harmonic. The detection winding (80) is preferably wound in the same statoric notches as the main winding, and to avoid an inductive coupling between the main winding (35-47) and the detection winding (80), a predetermined space phase shift is maintained between these two windings.
(FR)Dans un moteur a courant continu sans collecteur pourvu d"un rotor (11) a aimants permanents, on utilise une magnetisation des poles rotoriques (N, S) qui differe fortement de la forme sinusoidale. En plus de l"enroulement principal (35-47) qui sert a l"entrainement du moteur, le stator est en outre muni d"un enroulement de detection (80) agence de maniere a capter une harmonique de la tension induite dans le stator par les poles rotoriques (11), par exemple la deuxieme harmonique. L"enroulement de detection (80) est avantageusement bobine dans les memes encoches statoriques que l"enroulement principal, et la pour eviter un couplage inductif entre l"enroulement principal (35-47) et l"enroulement de detection (80), un dephasage spatial determine est maintenu entre ces deux enroulements.
