Abstract

Si propone un motore elettrico, in particolare motore a corrente continua eccitato mediante magnete permanente, il quale motore è dotato di un dispositivo per il rilevamento della posizione del rotore, del numero dei giri e/o del senso di rotazione, il quale dispositivo presenta almeno un elemento (25) sensibile al campo magnetico. Tale elemento (25) sensibile al campo magnetico è applicato sullo statore (10) del motore per rilevare le oscillazioni del flusso magnetico, con motore in funzione, dovute alla posizione del motore, ove sono previsti mezzi elettronici atti a valutare i segnali di detto elemento (25) sensibile al campo magnetico. In tal modo è possibile prevedere un dispositivo per il rilevamento della posizione del rotore, del numero dei giri e/o del senso di rotazione, senza che il motore debba essere modificato dal punto di vista costruttivo. Inoltre, tale dispositivo è realizzabile in modo semplice e a costi economici e può anche essere applicato in un secondo tempo a motori esistenti. (Figura 3).An electric motor is proposed, in particular a DC motor excited by a permanent magnet, which motor is equipped with a device for detecting the position of the rotor, the number of revolutions and / or the direction of rotation, which device has at least an element (25) sensitive to the magnetic field. This element (25) sensitive to the magnetic field is applied on the stator (10) of the motor to detect the oscillations of the magnetic flux, with the motor running, due to the position of the motor, where electronic means are provided for evaluating the signals of said element (25) sensitive to magnetic field. In this way it is possible to provide a device for detecting the position of the rotor, the number of revolutions and / or the direction of rotation, without the motor having to be modified from the constructive point of view. Furthermore, this device can be manufactured in a simple way and at economic costs and can also be applied later to existing engines. (Figure 3).
