Technical field

The utility model relates to a kind of motor, especially relates to a kind of magnetic suspension mixing birotor, two stator motor.

Background technology

At present, seriously polluted along with the reducing day by day of petroleum resources, atmospheric environment, people pay close attention to electric motor car more, and in these short several years, the electric motor car industry is popularized by sporadicly being distributed on a large scale by not having to having, and has obtained development and significant progress at a high speed.

As everyone knows, electric motor car is to be driving with electric power, the distance that the direct decision of the size of its reserve of electricity is gone, and the conventional electric-powered car is because of the bottleneck of accumulate battery self, and often operating range is restricted, and also is the principal element that the restriction electric motor car is promoted and used.

The utility model content

To the problems referred to above, the purpose of the utility model is to provide a kind of magnetic suspension mixing birotor, two stator motor, and it is used in the electric motor car, has the advantages that to improve the operating range of electric motor car greatly, to solve the problem that electric motor car exists in the prior art.

The purpose of the utility model is to realize through following technical scheme:

A kind of magnetic suspension mixing birotor, two stator motor; It comprises casing, and first rotating shaft of stretching in the casing is installed on the sidewall of said casing, is provided with at least one group of permanent-magnet suspender between said first rotating shaft and the chassis sidewall; The first rotor is installed in the end that said first rotating shaft is stretched in the casing; Cooperate the first rotor and its arranged outside that first stator is arranged, said first stator connects draws lead, on another sidewall of installation first rotating shaft second rotating shaft is installed relatively on the said casing; Be provided with at least one group of permanent-magnet suspender between said second rotating shaft and the chassis sidewall; Said second rotating shaft stretch in the first rotor and and the first rotor between be provided with at least two group permanent-magnet suspenders, and in said second rotating shaft second rotor is installed, said second rotor is arranged at the outside of first stator; Cooperate second rotor in its arranged outside second stator to be arranged, said second stator connects draws lead.

Especially, said permanent-magnet suspender comprises first permanent magnet and second permanent magnet of working in coordination, and said first permanent magnet is identical with the corresponding magnetic pole of second permanent magnet.

The beneficial effect of the utility model is that said mixing birotor, two stator motor drive the first rotor and rotate after the energising of first stator under the effect of electromagnetic force; Thereby, simultaneously, be in the second outer rotor of first stator and under the effect of electromagnetic force, rotate for electric motor car provides power drive; During second rotor rotation and second stator form generator; Adopt permanent magnet suspension between first and second rotating shaft and the casing and between second rotating shaft and the first rotor, significantly reduced the frictional force that the course of work produces, compared with prior art in electric vehicle running; Can also generate electricity and be stored in the storage battery of electric motor car; Not only improved the operating range of electric motor car greatly, and the machine operation energy loss is little, has improved the transformation efficiency of energy.
