Between there are rotational speed difference, i.e. 5 rotor speed of the first outer rotor permanent magnet is greater than 8 revolving speed of internal rotor permanent-magnetic body.In order to make outside first
Rotational speed difference can be manually set in range between rotor permanent magnet 5 and internal rotor permanent-magnetic body 8, and the present invention devises a not homopolarity
Property be along the circumferential direction alternately arranged, form magnetic open circuit disjunctor and the second outer rotor permanent magnet for being fixed on outer magnet rotor matrix 18
7, the electromagnetic induction coil 6 being fixed on 19 iron core 22 of electromagnetic induction coil matrix, the output end a of electron speed regulator 2 and output
End b is connect by slip ring -3 and slip ring 24 with electromagnetic induction coil 6, and two circuit closed accesses are constituted.
Due to existing between the first outer rotor permanent magnet 5 and the second outer rotor permanent magnet 7 and internal rotor permanent-magnetic body 8
One rotational speed difference, the electromagnetic induction coil 6 being wound on 19 iron core 22 of electromagnetic induction coil matrix are cutting the second external rotor permanent magnet
When 7 magnetic line of force of body, generate induced current (coil windings are close access), and induced current flows through electromagnetic induction coil 6 and is produced
Torque of magnetic force is generated between the magnetic field in raw magnetic field and the second outer rotor permanent magnet 7.Torque of magnetic force size passes through electron speed regulator
2 are adjusted to carry out.The parameter that electron speed regulator 2 can be set as needed is adjusted, and the bigger output of electric current reaches setting
Velocity Time is shorter, otherwise the smaller output of electric current reaches the longer of setting speed time.Realize it is flexible accelerate starting with
The purpose that deceleration stops.
But the above specific embodiments are only exemplary, is to preferably enable those skilled in the art
