Patent ID: 10461619

Abstract:
[Problem]An object of the present invention is to provide the motor which is possible to obtain the skew effect within the rotor gap surface by arranging the respective magnetic pole pitches at imbalance positions without causing the increasing of the magnet machining cost and the rotor assembly time, and the electric power steering apparatus equipped with the motor and a vehicle.[Means for Solving the Problem]The present invention is a motor that has a skew effect within a rotor gap surface of a mechanical angle one-cycle, wherein a rotor magnetic pole comprises plural magnetic salient pole portions by means of magnetic material, an N-pole and an S-pole magnets are alternately arranged on a rotor surface between the magnetic salient pole portions, and magnetic pole pitches of an electrical angle one-cycle, which comprise the magnetic salient pole portions and the N-pole and the S-pole magnets, are unevenly arranged.
