Embodiment Construction
[0017] Such as figure 1 The shown dual-stator reluctance angle sensor includes an inner stator 2, a rotor and an outer stator 8, a first sinusoidal air gap 3 is arranged between the inner stator 2 and the rotor, and a second sinusoidal air gap is arranged between the outer stator 8 and the rotor. Sinusoidal air gap7. The rotor includes a magnetic isolation ring 5 , an inner rotor part 4 arranged on the inner wall of the magnetic isolation ring 5 , and an outer rotor part 6 arranged on the outer wall of the magnetic isolation ring 5 . The main function of the magnetic isolation ring 5 is to separate the magnetic fields generated by the first excitation winding 17 and the second excitation winding 12 to avoid the mutual influence of the two, so as to improve the detection accuracy of the double-stator reluctance angle sensor of the present invention. Both sides of the magnetic isolation ring 5 are provided with grooves that limit the relative rotation of the inner rotor part 4 ...
