The electricity of radial magnetic field modulating described in Chinese patent CN101951090A and present embodiment
The operation principle that machine is adopted has certain similarity, but two schemes are not in terms of frame for movement, magnetic structure, motor performance
With, show as follows：
1. in frame for movement, the modulation rotor of CN101951090A schemes is located between stator and p-m rotor, and
And modulating rotor is made up of magnetic inductive block and non-magnetic block gap, is not allowed by permeability magnetic material between two neighboring magnetic inductive block
Being made of one connects it, could so realize magnetic field modulation function, and then ensures the electromagnetic performance of motor.Therefore, existing side
The major issue that case faces be how to take into account motor electromagnetic performance ensure modulation rotor simultaneously again because of interval setting magnetic inductive block and
The non-magnetic piece of problems of mechanical strength brought.
Application scheme, adjustable magnetic rotor is located at innermost layer, and protrusion unit 7-2 of multiple magnetic conduction functions equally realizes magnetic field
These protrusion units 7-2 need to make its connection to be just more beneficial for the main magnetic of motor with permeability magnetic material on modulation function, and magnetic circuit
Road flux closure (see main magnetic circuit path in Figure 11), so as to ensure motor electromagnetic performance.Therefore, from structure, it is only necessary to adopt
Same permeability magnetic material makes the integrated adjustable magnetic rotor with multiple protrusion units 7-2, you can realize the adjustable magnetic of adjustable magnetic rotor 7
Function.And importantly, such structure significantly increases the mechanical strength of adjustable magnetic rotor 7, so as to solve existing side
The problem that motor performance and mechanical strength in case can not be taken into account.
It can be seen from principles illustrated before present embodiment, the torque T of adjustable magnetic rotor 7mWill be greater than the defeated of p-m rotor 6
Go out torque TPM；Also " output torque T of modulation rotor 6 is described in CN101951090A3Will be greater than the output of p-m rotor 7
Torque T1" this technical characteristic, i.e., the two be required to the torque of torque of adjustable magnetic more than permanent magnetism, this requires the strong of adjustable magnetic rotor
Degree is greater than the intensity of p-m rotor, and just rationally, efficiency just can be higher, and the electric machine structure of present embodiment is exactly for the structure of motor
Meet this feature, therefore the electric machine structure of present embodiment is more reasonable, it is in hgher efficiency.
2. on magnetic structure, the permanent magnet leakage magnetic circuit of CN101951090A only have passed through one layer of air gap (internal layer air gap L2)
Can close (referring to Figure 10), by contrast, the permanent magnet leakage magnetic circuit of present embodiment is needed through two-layer air gap (internal layer air gap
L2 and outer layer air gap L1) could close (referring to Figure 11), therefore, the motor of present embodiment is fewer than CN101951090A leakage fields.
(the CN101951090A by taking the CN101951090A and present embodiment of same number of pole-pairs relation as an example：Stator number of pole-pairs is 4, forever
Magnet number of pole-pairs is 17, and magnetic conduction block number is 21；Present embodiment：Stator number of pole-pairs is 4, and permanent magnet pole logarithm is 17, and magnetic conduction is dashed forward
Unit 7-2 numbers are played for 21), the field waveform in ectonexine air gap L2 in two schemes is respectively such as Figure 12-Figure 15. contrast this 4
Zhang Tu, it can be seen that due to the leakage path difference in two schemes so that the field waveform of outer layer air gap in present embodiment
Differ markedly from the field waveform of outer layer air gap in CN101951090A, and in present embodiment outer layer air gap magnetic field amplitude
Also it is significantly greater than the magnetic field amplitude of outer layer air gap in CN101951090A.Therefore, based on present embodiment in the excellent of magnetic path connection
Gesture, present embodiment has more superior electromagnetic performance than CN101951090A.It is right still by taking two above-mentioned concrete models as an example
The key technical index (back-emf, electromagnetic torque) of CN101951090A and present embodiment has carried out simulation analysis, emulation knot
Fruit such as Figure 16-Figure 18.From simulation result as can be seen that the back-emf amplitude of present embodiment is significantly greater than CN101951090A's
Back-emf amplitude；The average electromagnetic torque of adjustable magnetic rotor is significantly greater than in CN101951090A and modulates rotor in present embodiment
Average electromagnetic torque；The average electromagnetic torque of p-m rotor is significantly greater than in CN101951090A and modulates ring in present embodiment
The average electromagnetic torque of rotor.Therefore, CN101951090A is compared, present embodiment can obtain higher torque density and work(
Rate density.
The operation principle of the regulation motor of Axial and radial torque is analyzed in detail below：
Because the second p-m rotor 12 is fixed on p-m rotor output shaft 9, the second p-m rotor 12 is turned with permanent magnetism
The rotating speed rotation of sub- output shaft 9.When second stator winding 11-2 is passed through polyphase alternating current, produces in space and turn with the second permanent magnetism
Sub 12 magnetic field number of poles identical rotating excitation fields, produce torque and are applied to the second p-m rotor 12 by the interaction in magnetic field
On, while being delivered on p-m rotor output shaft 9.
When the torque that radial direction double-rotor machine is input on p-m rotor output shaft 9 is more than the torque that load needs, lead to
The electric current of control input the second stator winding 11-2 is crossed, makes Axial and radial torque regulation motor be operated in dynamic brake state, now
