The utility model is installed to one of as follows using embodiment in motor：
Rotor 11 of the present utility model and end cap 13 are installed on motor shaft 20, the opposite side peace of rotor 11
Fixed rotor 12 is filled, rotor 11 is provided with bottom plate 114 towards the side of fixed rotor 12, and the surface loop of fixed rotor 12 is around certainly
Body is circumferentially with the alternating expression pole piece 30 consistent with the arrangement mode of rotor 11, and makes the alternating expression on the surface of fixed rotor 12
The alternating expression pole piece 30 on pole piece 30 and the surface of rotor 11 circumferentially staggers an angle [alpha], and angle [alpha] is too whard to control greatly,
It is too small not reach the purpose automatically adjusted, therefore the alternating expression pole piece 30 on the surface of the utility model fixed rotor 12 turns with rotation
The span for the angle [alpha] that the alternating expression pole piece 30 on sub 11 surfaces circumferentially staggers is at 13 ° -17 °.Rotor 11 and fixation
Rotor 12 forms the rotor 10 of an entirety, is placed in electric machine casing 1, wound motor on the madial wall of electric machine casing 1
Rotor 10 sets fixed coil, the fixed coil of the inner side of electric machine casing 1 is powered to motor power supply by lead 2, fixed coil
The alternating expression pole piece 30 in caused magnetic field and the surface of rotor 10 interacts, and makes the integral-rotation of rotor 10, motor
Drive motor axle 20 rotates rotor 10 simultaneously.Alternating expression pole piece 30 and the surface of rotor 11 due to the surface of fixed rotor 12
The circumferentially offset angular α of alternating expression pole piece 30, the alternating expression pole piece 30 and the table of rotor 11 on the surface of fixed rotor 12
The alternating expression pole piece 30 in face can respectively with fixed coil caused by electromagnetic field interact,
At the same time due to the alternating expression pole piece 30 and the alternating expression magnetic on the surface of rotor 11 on the surface of fixed rotor 12
Pole piece 30 circumferentially staggers an angle [alpha], and caused magnetic field can cancel out each other a part respectively for fixed rotor 12 and rotor 11,
Reduce the overall magnetic field intensity of rotor 10, equivalent to the computational length La for shortening the magnet of rotor 10, and according to
The magnet computational length La formula of formula one：In formula：La is the computational length of rotor magnet；aδFor
Pole embrace；A is electromagnetic load；BδFor air gap flux density；DaFor rotor diameter；For efficiency；P is number of pole-pairs, and n is rotating speed；kDFor
Constant,
In the case where other correlation computations coefficients are constant, n is inversely proportional with La, i.e., when the overall magnetic field of rotor 10 is strong
Degree reduces so that when the computational length La of rotor magnet shortens, and motor speed n increases, the increasing of improved efficiency motor speed
Add the corresponding power output for improving motor, make motor operation in high efficiency range.
When vehicle, which loads, to be increased, resistance can be applied on motor shaft 20 caused by load, in order to overcome resistance, motor
Power meeting automatic adjustment height, making to increase by the electric current of the inner side fixed coil of electric machine casing 1, fixed coil produces bigger magnetic field,
Until magnetic field can overcome the support force of compression spring 42 to make 11 turns of rotor with active force caused by alternating expression pole piece 30
It is dynamic, while drive pin 41 to compress compression spring 42 by positioning push pedal 43.Rotor 11 rotates necessarily relative to end cap 13
Angle after, the alternating expression pole piece 30 on the surface of fixed rotor 12 and the alternating expression pole piece 30 on the surface of rotor 11 is staggered
Angle diminish, the overall magnetic field intensity of rotor 10 is improved, so as to equivalent to the computational length for making rotor magnet
La is elongated, and according to formula one above, motor speed n can be reduced accordingly, now, because power output is constant, is operated according to motor
Formula two：Power output=rotating speed * torsion/9.55, motor torsion can synchronously get a promotion with output torque.
With load constantly increase, the degree that compression spring 42 is compressed constantly increases so that rotor 11 is with respect to end cap
The angle of 13 rotations constantly increases, and the overall magnetic field intensity of rotor 10 is more and more stronger, and La is increasing, and the output of motor turns
Square increases therewith, is α up to being rotated up to angle, now the alternating expression pole piece 30 and rotor 11 on the surface of fixed rotor 12
The angle that the alternating expression pole piece 30 on surface circumferentially staggers is 0 °, and both are consistent completely, reaches maximum output torque.
