Direction angle in 90 °；The magnetizing direction of radial magnetizing permanent magnetism body in per adjacent the two poles of the earth is on the contrary, cutting in per adjacent the two poles of the earth
It is opposite to the magnetizing direction of charging permanent magnet.Halbach permanent uses rubidium iron boron rare earth permanent-magnetic material.
The magnetic circuit for the inside and outside motor that motor of the present invention is included is as shown in Figure 3.From figure 3, it can be seen that outer motor magnetic circuit

Generate torque, the torque of generation is reluctance torque.In interior motor magnetic circuit, magnetic circuit is generated by inner stator 2, and with Halbach forever
Magnet 6 interlinks, and by armature winding magnetic linkage and permanent magnet flux linkage interaction output torque, turns so the torque generated is permanent magnetism
Square.In order to ensure the permanent-magnet torque of output and reluctance torque decoupling, it is necessary to assure in the case of unloaded and load, interior motor magnetic circuit
With the decoupling of outer motor magnetic circuit.
In order to accurately illustrate the effect of motor magnetic circuit decoupling inside and outside the present invention, the distribution of unloaded and external stator integer slot is given
Formula winding 3 is passed through the back-emf variation of the external stator integer slot distribution winding 3 and fractional-slot concentratred winding 4 under current conditions.
From Fig. 4 (a) it can be seen that under no-load condition, inner stator fractional-slot concentratred winding 4 has back-emf and external stator integer slot is distributed
3 back-emf of formula winding is 0, so as to which the magnetic linkage for obtaining permanent magnet generation only interlinks with inner stator 2, passes through external stator without magnetic linkage
1.By Fig. 4 (b) it can be seen that in the case where external stator integer slot distribution winding 3 is passed through current conditions, inner stator fractional-slot concentrate around
It is almost consistent when the back-emf that group 4 obtains is with zero load, illustrate the validity of inside and outside motor magnetic circuit decoupling.So as to illustrate this hair

For：During interior motor wheel hub type Halbach magneto independent roles, as the variation that electric current angle changes output permanent-magnet torque is bent
Line；During outer motor synchronous magnetic resistance motor independent role, as electric current angle changes the change curve of output reluctance torque；Inside and outside two
Winding is powered simultaneously, the curve that the output torque that motor is operated under built-in permanent magnetic motor mode changes with electric current angle.
