specific Embodiment approach 1
[0014] Specific implementation manner one: such as figure 1 As shown, the resolver of this embodiment is composed of a rotor 2, a stator 1, a first coil 4-1, a second coil 5-1, and a third coil 6-1. The outer surface of the rotor 2 and the stator 1 An air gap 3 is provided between the inner circular surfaces of the rotor 2; the outer circular surface of the rotor 2 is uniformly provided with P crests and P troughs, and the crests and troughs are smoothly connected to each other to form the wavy outer circular surface of the rotor 2, wherein , P is the number of pole pairs of the resolver; the inner circular surface of the stator 1 is provided with a plurality of through slots 1-2 along the axial direction, and there are convex teeth 1- between the two adjacent through slots 1-2. 1. The inner circular surface of the stator 1 is uniformly arranged with 4P convex teeth 1-1 along the circumferential direction, and the 4P convex teeth 1-1 are sequentially divided into 2P odd convex tee...
specific Embodiment approach 2
[0015] Specific implementation manner two: such as figure 1 As shown, the difference between this specific embodiment and the first embodiment is that the stator 1 and the rotor 2 are formed by superimposing a plurality of punched pieces of electrical steel. Other components and connection relationships are the same as in the first embodiment.
specific Embodiment approach 3
[0016] Specific implementation manner three: such as figure 1 As shown, the difference between this specific embodiment and the first embodiment is that the number of turns of the second coil 5-1 and the third coil 6-1 is the same. Other components and connection relationships are the same as in the first embodiment.
