It is adjustable magnetic ring 3 between internal rotor and the second stator, the magnetizer of adjustable magnetic ring need to select the higher material of magnetic conductivity.It adjusts
Magnet ring is based on magnetic field modulation principle and changes air-gap permeance, and the magnetic field that internal rotor permanent-magnetic body is generated with the second stator permanent magnet is being adjusted
It is adjusted in the air gap of magnet ring two sides, makes in air-gap field that there is countless harmonic fields, and interacted: is i.e. addition adjustable magnetic ring
After 3, the magnetic field that the magnetic field or the second stator permanent magnet 4-3 that internal rotor permanent-magnetic body 2-1 is generated generate, magnetic flux density space harmonics
Rotation speed change, that is, the velocity of rotation of object, therefore forms not homopolarity pair in air gap where being different from permanent magnet
Several harmonic fields.The magnetic for the identical number of pole-pairs that the air-gap harmonic magnetic field of internal rotor and adjustable magnetic interannular is generated with other side permanent magnet

Electrical excitation source will be generated after being passed through direct current to excitation winding 4-2, it and permanent magnet excitation source collective effect generate excitation field,
When electricity excitation magnetic field is contrary with permanent magnetic field, air-gap field weakens, and when the two direction is identical, air-gap field enhances, and leads to
DC excitation size of current and direction are overregulated to realize adjustable magnetic function, to realize torque or rate performance requirement；Another portion
Point electric energy again through DC/AC voltage inverter 8 convert by three phase sine alternating current be sent into the three-phase distribution armature of the second stator 4 around
To generate electromagnetic torque in group 4-1, internal rotor rotation, the modulated ring in magnetic field that the permanent magnet of 3 two sides of adjustable magnetic ring generates are driven
Torque is generated after modulation, and the torque of generation is passed into adjustable magnetic ring 3 by air-gap field.Engine is directly passed to adjustable magnetic ring
Torque and the electromagnetic torque acted on adjustable magnetic ring that three-phase distribution armature winding 4-1 in the second stator is generated are superimposed, altogether
Same-action drives hybrid vehicle to move ahead on adjustable magnetic ring.
With existing axial radial flux structure compound permanent-magnet machine there are the problem of compared with, on internal rotor of the present invention only
Permanent magnet and without winding, be easy to cooling, solve the problems, such as heating in winding and rotor dynamic balancing；It avoids simultaneously using electric brush slip ring knot
Structure, to realize motor non-brushing；Non-brushing keeps electric machine structure simple, improves energy converting between mechanical efficiency and reliability, is not necessarily to
Lubrication reduces maintenance cost；Using composite excitation, solves permanent magnet flux switch motor main field and adjust difficult, permanent magnet
The problem of irreversible demagnetization risk occurs；It is driven using magnetic gear, reduces mechanical wear and noise, had and overload self guarantor
