Embodiment
For the purpose of this utility model, technical scheme and advantage are better described, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of multi-degree of freedom spherical induction motor, as shown in Fig. 1,2,3,4,5, comprises shell 2, three groups of plane of symmetry γ stators 3 perpendicular to each other, β stator 4, α stator 5 and is arranged on stator around the hollow spherical rotor 1 in space and bearing 6.
Three groups of stator structures of described induction motor are consistent, and just fixed position, space is different, and its plane of symmetry is vertical between two, and three groups of stator enclosed spaces are spherical. The rotor of described induction motor is fixed between stator by multiple bearing, remains with certain thickness air gap between rotor and stator, and rotor outer surface is covered with layers of copper.
