(11) novel pure electric automobile field: under the main trend that current environmental protection and energy problem are concerned, to solve The shortcomings that orthodox car pollutes environment and uses non-renewable energy resources, the trend of accelerated development is presented in electric car；It is electronic simultaneously Automobile intelligence easy to accomplish, facilitates the safety for improving vehicle and service performance.Electric car is to its drive system Good with direct torque ability, torque density is high, reliable for operation, and big wait of speed adjustable range requires, and therefore, studies and develops Gao Shui Flat driving motor for electric automobile has great importance.

Conventional permanent magnet motor is generally divided into following 4 class: permanent magnet direct current motor, asynchronous starting permasyn morot, Brushless, permanently excited direct current motor and speed regulation permasyn morot.

Permanent magnet direct current motor and difference of the conventional DC motor in structure be the former eliminate excitation winding and Pole core, and being replaced with permanent magnetism magnetic pole has the characteristics that simple structure, high reliablity, high-efficient, small in size, light-weight, big Most permanent magnet direct current motors are micromotors, have obtained answering extensively in electronic toy, household electrical appliance, auto industry With wherein application development in the automotive industry is most fast.

It is essentially identical on brshless DC motor and speed regulation permanent magnetic synchronous motor structure, it is polyphase windings on stator, on rotor For permanent magnet, their main distinction is brshless DC motor according to rotor position information realization motor synchronizing.They the advantages of, exist In: brush-commutated device is eliminated, reliability improves；Loss is mainly generated by stator, and radiating condition is good；It is small in size, it is light-weight.

Asynchronous starting permasyn morot is with the difference on speed regulation permanent magnet synchronous motor structure: the former has on rotor Start winding or the integrated iron core with starting effect, energy self-starting can be in electric online operation without control system.

The difference that permanent magnet synchronous motor places mode according to the permanent magnet on rotor is adjusted the speed, surface-type rotor knot can be divided into Structure and two kinds of built-in rotor structure:

In surface-type rotor structure, permanent magnet is processed to arc, is directly anchored to the outer surface of rotor, and permanent magnet is direct Towards motor gas-gap, the magnetic flux that permanent magnet generates is directly over air gap and enters stator formation useful flux；With built-in rotor knot Structure is compared, and the permanent magnet in surface-type rotor structure is due to being rest directly upon rotor surface, and permanent magnet needs are processed into and rotor To form even air gap with the arcuate shape that air gap matches to guarantee, due to the frangible characteristic of permanent-magnet material, accurate processing compared with It is more demanding to processing technology for complexity, it is at high cost.Further, since permanent magnet is rest directly upon rotor surface, motor operation When, due to the effect of centrifugal force, it is desirable that no latitude band binding and fixing must be wound outside permanent magnet, when avoiding rotor high speed rotation forever Magnet falls off damage；Since the air gap flux density of permanent magnet and the width of permanent magnet are proportional, when permanent magnet When width determines, empty load of motor air gap flux density determines therewith, and when being actually designed, motor permanent magnet width is by unloaded air gap The restriction of flux density；Since permanent magnet is directly facing motor gas-gap, when motor needs to carry out weak magnetism speed expansion control i.e. using i_dDiffer When 0 control, the magnetic flux that armature winding generates can face the risk of irreversible demagnetization directly through permanent magnet, permanent magnet；Due to The magnetic conductivity and air of permanent-magnet material are very close to the reactance of d axis and q axis is equal in surface-type rotor structure, when motor operation only Torque is generated by permanent magnetic field and armature field interaction, reluctance torque cannot be generated, the torque density and power of motor are close It spends lower compared with built-in rotor structure；Surface-type rotor structure cannot place starting mouse cage on the outside of rotor, and motor cannot Realize self-starting.

In built-in rotor structure, permanent magnet is embedded into rotor core according to certain requirement, and permanent magnet is in iron core Middle generation magnetic flux, the insertion of permanent magnet is various informative in built-in rotor structure, and permanent magnet can be carried out according to different requirements Poly- magnetic effect is realized in series-parallel combination, meets actual performance needs；Compared with surface-type rotor structure, in built-in rotor structure Permanent magnet be not placed in rotor surface not instead of directly, be embedded into rotor core by certain form, permanent magnet is not It is directly facing motor gas-gap, permanent magnet is fixed by the permanent magnet trough in rotor, without no latitude band bundled fixed, rotor machine Tool structural integrity is good, high reliablity when motor high speed rotation；Permanent magnet can be flexible with parallel connection by connecting between each other Poly- magnetic effect is realized in combination, can obtain the much bigger air gap flux density of specific surface formula rotor structure, power of motor density and torque Density is higher than surface-type rotor structure；Motor pole embrace and air gap flux density are not directly dependent upon, can be only respectively in design It is vertical to be configured；Under overload condition, since permanent magnet is not directly facing air gap, the risk of demagnetization can be reduced.

There are following technical disadvantages for existing permanent magnet synchronous motor:

1, the permanent magnet magnetic kinetic potential of permanent magnet synchronous motor is fixed, and rear main flux is made just it has been determined that can not be to motor in motor Every pole magnetic flux controlled, output-constant operation narrow range, speed adjustable range is not wide in range enough.

2, the path passed through according to d axis magnetic flux when weak magnetic is different, and the permanent magnet synchronous motor of existing built-in rotor structure can To be divided into two classes, one type, when carrying out weak magnetic control, the d axis magnetic flux that armature winding generates can pass through the permanent magnet of motor, Cause permanent magnet irreversible demagnetization, in addition a kind of, when carrying out weak magnetic control, the d axis magnetic flux that armature winding generates is without forever Magnet closure, but the magnetic field that d shaft current generates forces more rotor fluxs by the end of motor and end cap closure, it is significant to increase The big leakage magnetic flux of motor, and since motor end magnetic resistance is usually more much bigger than air-gap reluctance, d required for weak magnetic Shaft current is larger, significantly increases the cost and winding copper loss of power of motor inverter.

3, when existing permanent magnet synchronous motor carries out weak-magnetic speed-regulating, still led to using the in the majority of vector controlled in speed-regulating system It is often to be controlled by controller stator armature electric current, is not that the weak magnetic of motor is adjusted from body construction, electricity The weak magnetic property of machine is undesirable, and controller cost and control difficulty increase.
