Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.
[0027] like figure 1 and figure 2 As shown, the multi-stage rotary transformer of the present invention includes a rotor 1 , a stator 2 , an excitation winding 4 , a sine winding 5 , and a cosine winding 6 . Both the rotor 1 and the stator 2 are formed by laminating multiple silicon steel sheets with high magnetic permeability. An air gap 3 is uniformly provided between the inner circular surface of the stator 2 and the outer circular surface of the rotor 1 . The outer circular surface of the rotor 1 is evenly provided with P wave crests and wave troughs. The wave crests and the wave troughs are smoothly connected to each other to form the wavy outer circular surface of the roto...
