Description
Technical field
The invention belongs to direct-drive motor, be specifically related to a kind of power drive direct current machine that is specially adapted to electric automobile.
Background technology
Along with the influence of energy crisis to automobile industry, research and development and the utilization of electronic alternative automobile have progressively been carried out at present.The key technology point of electric automobile is mainly battery, charger, motor and controller, and wherein motor is the greatest factor that influences utilization of power efficient.The motor of DC driven become electric automobile the drive motors that generally adopts, existing direct current machine need adopt commutator realize will input direct current be converted to alternating current in the rotor element of winding.Existing direct current machine is in use still because be subjected to the structural design of service condition to cause motor to generate heat easily, and be easy to cause shorten the useful life of linear electric motors because entering dust and moisture, can't stablize and realize for a long time the use of high-power particularly electrocar and electronic public transport bus car.
Summary of the invention
The invention provides the power drive direct current machine of the electric automobile of a kind of structural design compact and reasonable, long service life, its starting torque is big, regenerative voltage is high, peak current is little and efficient is high, motor is difficult for heating, is suitable for the use that various electric automobiles comprise electrocar and electronic public transport bus car.
The technical solution adopted in the present invention is as follows:
A kind of power drive direct current machine of electric automobile, comprise stator and rotor, it is characterized in that described stator has stator case and the commutator housing of a coaxial setting, stator case inwall fixed stator magnetic track and magnetic pole of the stator, fixed rotor is every lid between stator case and the commutator housing, rotor comprises an electric machine main shaft, and electric machine main shaft is provided with electronics rotor, low pressure armature and high pressure armature in described stator case the inner, and described electric machine main shaft arranges commutator in the commutator housing.
In the embodiment, the rear end of the front end of described stator case and commutator housing arranges bearing protecgulum and bearing bonnet respectively, and the motor bearings that electric machine main shaft is installed is set respectively on bearing protecgulum and the bearing bonnet.
In one execution mode, described magnetic pole of the stator is fixed in the stator magnetic track, and described magnetic pole of the stator is that annular spread is arranged on the tile magnetic pole in the stator magnetic track.
In one execution mode, described rotor is separated into independently space every lid with described stator case and commutator housing, and described rotor is provided with the axis hole that common-battery machine main shaft passes every the lid middle part.
In another execution mode, offer the bar shaped straight trough that circumferentially arranges around electric machine main shaft on the described rotor, the inboard winding of described bar shaped straight trough arranges high-tension coil, and low-voltage coil is put in the outer felt winding of described bar shaped straight trough.
In the execution mode, described commutator inner walls is set side by side with low pressure brush and high pressure brush again.
The power drive direct current machine of this electric automobile has adopted rotor every lid, stator case and commutator housing are separated into two independently spaces, play preferable protection against the tide, dustproof effect, eliminated automobile with direct current machine because the defective that shortens the useful life that dust and condensation cause.The closed structure that stator case, commutator zoarium are realized whole power drive direct current machine by bearing protecgulum and the bearing bonnet of front and back end spiral-lock setting can be realized the compact type design of this direct current machine.Rotor, low-voltage line pivot, high-voltage line pivot, commutator are installed on the electric machine main shaft successively.The bar shaped straight trough of the circle of offering around the rotor circumference is used for low-voltage coil and high-tension coil are installed, and makes the speed-regulating range width of this direct current machine, peak current less.Stator case and commutator housing adopt the split design, can require according to the Technology design of commutator and rotor and stator to plan, are beneficial to suitability for industrialized production.
Beneficial effect of the present invention is, the power drive DC motor structure of this electric automobile is compact to design rationally, long service life, its starting torque is big, regenerative voltage is high, peak current is little and efficient is high, motor is difficult for heating, is suitable for the use that various electric automobiles comprise electrocar and electronic public transport bus car.
