Embodiment 1
[0023] In this embodiment, the flat disk-type magnetism-concentrating magnetic circuit structure used in the permanent magnet eddy current transmission device adopts a double magnetic coupling ring structure.
[0024] Such as Figure 1 to Figure 4 As shown, a flat-disc type magnetic circuit structure for a permanent magnet eddy current transmission device includes a permanent magnet rotor 23 as a driving rotor and an eddy current conductor rotor 22 as a driven rotor. The permanent magnet rotor 23 is composed of permanent magnets Rotor disk 2, twelve sets of inner ring permanent magnet groups 3 and sixteen sets of outer ring permanent magnet groups 4, the inner and outer ring permanent magnet groups are bonded and fixed on the surface of the permanent magnet rotor disk 2 through magnetically conductive glue, And uniformly distributed in the circumferential direction to form inner and outer magnetic coupling rings; the permanent magnet rotor disc 2 is in the shape of a disc and ...
Embodiment 2
[0032] Each set of magnetic circuit structures in the flat-disk type magnetism-concentrating magnetic circuit structure used in the permanent magnet eddy current transmission device of this embodiment adopts a single magnetic coupling ring structure.
[0033] Such as Figure 5 to Figure 7 As shown, a flat-disc type magnetic circuit structure for a permanent magnet eddy current transmission device includes a permanent magnet rotor 23 as a driven rotor and an eddy current conductor rotor 22 as a driving rotor.
