Abstract

Viene proposto un motore elettrico, specialmente un motore a corrente continua eccitato con magneti permanenti, il quale è dotato di un dispositivo per rilevare la posizione del rotore, il numero di giri e, oppure il senso di rotazione, che presenta almeno un elemento 25 sensibile al campo magnetico. Questo per rilevare variazioni del flusso magnetico, dipendenti dalla posizione del rotore, è montato sullo statore del motore, laddove sono previsti mezzi elettronici per valutare i segnali di questo elemento 25 sensibile al campo magnetico. Sono inoltre previsti mezzi 42 per eliminare o ridurre la parte indesiderata di campo della corrente di indotto del flusso magnetico nei segnali dell'elemento 25 sensibile al campo magnetico, che possono essere eseguiti ad esempio nella forma di cavo assiale nell'ambito dell'elemento 25 sensibile al campo magnetico, per cui si verifica un indebolimento dell'indesiderato campo trasversale di indotto nell'ambito di questo elemento 25 (figura 1).An electric motor is proposed, especially a DC motor excited with permanent magnets, which is equipped with a device for detecting the position of the rotor, the number of revolutions and, or the direction of rotation, which has at least one sensitive element 25 to the magnetic field. This for detecting variations in the magnetic flux, dependent on the position of the rotor, is mounted on the stator of the motor, where electronic means are provided for evaluating the signals of this element 25 sensitive to the magnetic field. Means 42 are also provided for eliminating or reducing the undesired field part of the armature current of the magnetic flux in the signals of the element 25 sensitive to the magnetic field, which can be carried out for example in the form of an axial cable within the element 25 sensitive to the magnetic field, whereby a weakening of the undesired armature transverse field occurs within this element 25 (Figure 1).
