The invention relates to electrical engineering, in particular, to devices employed in a step magnetoelectric motor, and it is intended for generating the Sin and Cos of electric signals that uniquely determine an armature position relative to toothed structure of a stator. To increase the accuracy the sensor contains two composite U-shaped magnetic conductors, on pole cores of which the teeth are formed. The group coordinates difference of the teeth being equal to (α±0,5) Z, where α is an integer, Z is the teeth spacing and 0,5 represents the decimal notation of ½. A permanent magnet is connected in series with one of the constituents of U-shaped magnetic conductors, and the magnetic induction converters are placed in proximity to the pair of the like magnetic poles of the magnetic conductors.
A position sensor for the armature of a step magnetoelectric motor, comprising two composite U-shaped magnetic conductors, on the core poles of each magnetic conductor teeth are formed, which group coordinates difference is equal to (α+0,5) Z, and further comprising two magnetic induction converters, characterized in that in one of the constituents of U-shaped magnetic conductors a permanent magnet is connected in series, and the magnetic induction converters are placed in either mechanical or magnetic proximity to the pair of like core magnetic poles of a pair of U-shaped magnetic conductors in such a way, that the converters output signal is directly proportional to the difference of the magnetomotive forces of these magnetic poles, wherein α is an arbitrary integer;
