Control device of a motor with electronic switching comprising singularities distributed angularly

摘要

The invention relates to a device for controlling an electronic switching motor comprising an encoder (2) provided with a main multipolar track (2a) and of a multipolar track (2b) called the "turn cue ", the said tracks, each comprising n sectors (2c), which are identical and angularly distributed respectively on the entire circumference of the tracks, the sectors (2c) of the top turn track (2b), each comprising m singularities (2b1) distributed angularly, the m singularities (2b1) being distributed angularly so that the top turn signal (c) is arranged so as, in combination with the signals a and b define the binary sequences of the angular length less than that of the sectors (2c) and which are representative of the absolute angular position of the coder (2) over a sector (2c) [invention also relates to a rolling bearing and an engine equipped with such a device, as well as a process for the control of such a motor.
