<P>PROBLEM TO BE SOLVED: To eliminate the influence of an external magnetic flux. <P>SOLUTION: A variable reluctance type resolver comprises a stator 50 having a plurality of teeth 51, and provided with a one-phase exiting winding and two-phase detection windings 61 and 62; and a rotor 20 selecting a shape so as to change a gap permeance with the teeth 51 into a sinewave-shape with rotations. A number of teeth 51 is made to be 6 about each axial double angle. One detection winding 61 of the two-phase detection windings is wound around two teeth T1 and T4 separated at 180° of an electric angle of the six teeth 51 (T1-T6) in the same winding direction, and the other detection winding 62 is wound around the rest four teeth T2, T3, T5, T6. The winding direction of the other detection winding 62 is same at the teeth separated at 180° of the electric angle, and opposite at the adjacent teeth. <P>COPYRIGHT: (C)2013,JPO&INPIT |
