Technical field
The present invention provides a kind of built-in tangential and Surface Mount radial permanent magnet steel wheel hub drive motor, belongs to electric motor of automobile technical field of electric appliances.
Background technology
Current and the matching used drive motor of electric automobile mostly adopts the direct current generator with carbon brush and mechanical commutator, although DC motor structure is simple, controllability is high, speed-regulating range width, control circuit is relatively easy, less costly, but owing to the magnetic field of direct current generator is produced by electricity Exciting Windings for Transverse Differential Protection, power consumption is many, output is little, additionally, due to there is carbon brush and mechanical commutator, not only limit the raising of direct current generator overload capacity and speed, if long-play, certainly will be required frequent maintenance and replacement carbon brush and diverter, therefore direct current generator energy consumption is big, fault rate is high, its serviceability needs further improvement.
Summary of the invention
It is an object of the invention to provide one and can overcome drawbacks described above, the magnetic field of hub driven motor is provided by permanent-magnet steel, few without electricity Exciting Windings for Transverse Differential Protection, power consumption, it does not have built-in tangential and the Surface Mount radial permanent magnet steel wheel hub drive motor of carbon brush and mechanical commutator, failure rate is low, its technology contents is:
Built-in tangential and Surface Mount radial permanent magnet steel wheel hub drive motor are made up of drive end bearing bracket, rear end cap, hub-type casing, rotor, stator, stator support, axle, it is characterised in that: hub driven motor rotor is radial magnetic field and the p-m rotor of tangential magnetic field resultant magnetic field；
nullThe p-m rotor of resultant magnetic field is by rectangle permanent-magnet steel、Hub-type casing、Rotor core、Fan annular is every magnetic air gap、Tile permanent-magnet steel forms，Rotor core is evenly equipped with even number and runs through the radial direction rectangular channel of rotor core thickness，Radially do not connect between the inner and the inner circle of rotor core of rectangular channel，The fan annular of rotor core thickness it is provided with through every magnetic air gap in the outer end of each radial direction rectangular channel，Adjacent fan annular does not connect every magnetic air gap，Fan annular does not connect between the outer end and the cylindrical of rotor core of magnetic air gap，The inner middle circular hole being provided with through rotor core thickness at adjacent two radial direction rectangular channels，The center of circle of multiple circular holes is all on same circumference，Do not connect between the inner and the inner circle of rotor core of circular hole，The diameter of circular hole is more than the diameter of screw，Iron rivet is through the circular hole on rotor core and rivets rotor core，Rectangle permanent-magnet steel is extremely relative with N by the N pole of adjacent two panels rectangle permanent-magnet steel、The S pole mode extremely relative with S is sequentially arranged at radially in rectangular channel，Mode that the polarity that formed by the polarity of the tile permanent-magnet steel medial surface rectangle permanent-magnet steel adjacent with two panels by tile permanent-magnet steel again is identical and being sequentially fixed on rotor core by pole shoe by screw，Rotor core is fixed in the inner circle of hub-type casing.
Operation principle: when permanent magnetism hub driven motor passes into by three-phase inverter after the three-phase alternating current of pulsewidth modulation, hub driven motor stator produces a space rotating magnetic field, it is magnetic field interaction produced by with rotor permanent magnet steel, rotor produces the rotating torques consistent with stator winding rotating excitation field direction, make hub driven motor p-m rotor rotate, and then drive electric automobile to run.
The present invention is compared with prior art, tile magnet steel is fixed in the inner circle of rotor core, rectangle permanent-magnet steel is embedded in the radial direction rectangular channel of rotor core, hub driven motor rotor field is provided jointly by radial magnetic field and tangential magnetic field, magnetic field intensity is big, power density is high, and few without electricity Exciting Windings for Transverse Differential Protection, power consumption, it does not have carbon brush and mechanical commutator, failure rate is low, there is the features such as efficiency height, compact conformation, reliable operation.
