Embodiment Construction
[0016] As shown in the figure, the inter-shaft permanent magnetic coupling mechanism of the present invention includes a coaxially arranged permanent magnet rotor 1 and a conductor rotor 2. Permanent magnets and conductors are respectively distributed on the permanent magnet rotor 1 and the conductor rotor 2. The permanent magnet rotor 1 There is a conical air gap 3 between the conductor rotor 2; the permanent magnet on the permanent magnet rotor 1 includes a main magnet 4 and an auxiliary magnet 5; a plurality of main magnets 4 are distributed along the circumference, and are arranged between adjacent main magnets 4 There are magnetizers 6 made of magnetically permeable materials; the auxiliary magnets 5 are located on the side of each magnetizer 6 away from the conductor rotor 2; Direction) is located in the circumferential direction of the permanent magnet rotor, and the magnetic pole direction of the adjacent main magnet 4 (indicated by the arrow direction in the figure) is...
