Embodiment Construction
[0041] The present invention will be further described below in conjunction with the accompanying drawings.
[0042] Such as figure 1 , figure 2 As shown, the present invention provides a rotor magnetic circuit decoupling high-speed hybrid excitation synchronous motor, including a casing and a stator winding 1, a stator core 2, a permanent magnet rotor 8, an electric excitation rotor 10, and an excitation structure arranged in the casing 11 and the rotating shaft; the stator winding 1 is embedded in the slot of the stator core 2; the stator core 2 is fixed on the casing, the stator core material can adopt the traditional punching structure, and the use of soft magnetic composite materials is more conducive to further reducing the core loss in the weak magnetic state ; The permanent magnet rotor 8 is seamlessly assembled with the electric excitation rotor 10-1 and the electric excitation rotor 10-2 on the rotating shaft.
[0043] The physical quantity symbols involved in the...
