Description
Technical field
The invention provides a kind of electromagnetism and permanent magnetism compound rectifier excitation driving motor for electric automobile, belong to electric motor of automobile technical field of electric appliances.
Background technology
The permanent-magnet steel of the hub driven motor rotor adopting on electric automobile at present sticks on hub-type internal side of shell mostly, permanent-magnet steel is directly in the face of air gap, electric automobile is met barrier while blocking in overload or driving wheel, stator winding produces larger impulse current, permanent-magnet steel is under the armature reaction effect of impulse current, may produce irreversible demagnetization, once permanent-magnet steel forms irreversible demagnetization, drive motors Efficiency Decreasing, power, moment of torsion declines rapidly, in addition, drive motors air gap internal magnetic field is only improved by permanent-magnet steel, magnetic field intensity is little, power density is low, its serviceability needs further improvement.
Summary of the invention
The object of this invention is to provide one and can overcome above-mentioned defect, the magnetic field in drive motors air gap is provided jointly by permanent-magnet steel and electric excitation winding, and magnetic field intensity is large, the electromagnetism that power density is high and permanent magnetism compound rectifier excitation driving motor for electric automobile, and its technology contents is:
