The winding device of a reluctance resolver is disclosed in the prior art in the 2015, 4.15, for example, in chinese patent document CN 204270853U. Although the same excitation effect can be obtained by changing the winding method, the winding method can be used for winding the sine coil or the cosine coil four times, for example, half of the sine coil is wound firstly, half of the cosine coil is wound secondly, the other half of the sine coil is wound, and the other half of the cosine coil is wound finally. The sine coil and the cosine coil are alternately wound in two halves, the same winding is not continuously completed, and the middle of the winding is cut off and then connected, so that two middle joints are added, the production is inconvenient, and hidden danger is increased.
