Abstract
A device for controlling an electronically switched motor comprising a coder () provided with a main multipole track () and a so-called 'revolution pip' multipole track (), the said tracks each comprising N identical sectors () angularly distributed respectively over the entire circumference of the said tracks, the sectors () of the revolution pip track () each comprising M angularly distributed singularities (), the M singularities () being distributed angularly so that the revolution pip signal (C) is arranged so as, in combination with the signals A and B, to define binary sequences of angular length less than that of the sectors () and which represent the absolute angular position of the coder () on a sector (). The invention also relates to a bearing and a motor equipped with such a device, as well as a method for controlling such a motor.
