ABSTRACT:
A device for controlling an electronically switched motor which includes a coder (2) having a main multipole track (2a) and a so-called “revolution pip” multipole track (2b); a fixed sensor (3) delivering two digital position signals (A, B) and one revolution pip signal (C); a circuit for switching the currents in the phase windings of the motor which comprises2*P*N switches; a control circuit for the switching circuit which is able to supply the switching signals for the switches which correspond to the state of the logic determined by the revolution pip signal (C) or by the position signals (A, B). The control device can be combined with a bearing and/or a motor equipped with such a device.
