An rotor position sensor of the inductive type comprises a stator collected from armature shits of an asynchronous motor with two systems of teeth formed on the said motor, excitation system and signal systems comprising by two pairs of teeth with angle shift of120º, three excitation windings put on the corresponding pairs of teeth, and three signal windings, each of which comprises two opposite connected coils located on the neighboring teeth between excitation windings and a p-teeth rotor with tooth width equol to stator tooth width. In the outhang arias of signal windings and excitation winding in radial direction magnetically conductive plates made of electrotechnical steel are installed. |
