Definitions
- the present invention relates to a variable magnetoresistive type resolver including an outer stator having an excitation winding and an output winding and an inner rotor having a salient pole.
- a resolver is a kind of sensor for precisely measuring the rotational speed and the rotation angle of a motor.
- a variable reluctance type resolver to which the present invention belongs includes both an excitation winding and an output winding. It has a relatively simple structure in which a rotor having an elliptic or multipole shape is located inside the stator.
- variable magnetoresistive resolver having such a structure has been disclosed in Japanese Patent Application Laid-open No. Hei 8-178610, "Barrier reluctance type angle detector” (published: July 12, 1996).
- FIG. 1 is a view attached to the Japanese Laid-Open Patent Publication, wherein the rotor 10 has four protrusions 10a formed therein, and the excitation winding and the output winding are accommodated in the slot 11a of the stator 11.
- the AC voltage induced from the rotor 10 changes while being output due to the protrusion 10a.
- Figure 2 is an improved shape of the rotor 20, the outer circumferential surface of the eight elliptical protrusions 20a are formed at regular intervals of 45 degrees in the circumferential direction.
- the present invention provides a variable magnetoresistance type comprising a stator configured to receive an excitation winding and an output winding in a plurality of slots formed on an inner circumferential surface of an annular shape, and a rotor disposed to have a predetermined gap with an inner circumferential surface of the stator.
- the rotor is a variable magnetic, characterized in that the tooth-shaped protrusions and the flat surface is alternately formed on the outer circumferential surface, the length of the circumferential direction of the protrusion is formed larger than the length of the circumferential direction of the flat surface Provide a resistive resolver.
- the salient pole portion may have an inclined surface that is set to be greater than or equal to 90 degrees and less than or equal to 145 degrees with respect to the flat surface.
- the inclined surface may be set to 113 degrees.
- the protrusions and the flat surface may be formed to be arranged alternately each of the eight in the circumferential direction of the rotor.
- the circumferential surface of the protrusion may have a central angle of 29 degrees, and the flat surface may have a central angle of 15 degrees.
