Background technology
Current and electric automobile matching used driving motor mostly uses the unidirectional current with carbon brush and mechanical commutator
Machine, although DC motor structure is simple, controllability is high, speed-regulating range width, control circuit are relatively easy, cost is relatively low, but
Owing to the magnetic field of direct current generator is produced by electrical excitation winding, power consumption is many, output is little, additionally, due to there is carbon brush and machine
Tool diverter, not only limits the raising of direct current generator overload capacity and speed, and if long-play, certainly will need through
Often safeguarding and change carbon brush and diverter, therefore direct current generator energy consumption is big, fault rate is high, and its serviceability awaits changing further
Enter.
Summary of the invention
It is an object of the invention to provide one and can overcome drawbacks described above, the rotor field of hub driven motor is carried by permanent-magnet steel
Confession, few without electrical excitation winding, power consumption, do not have carbon brush and mechanical commutator, failure rate is low electric vehicle invisible magnetic pole with
Tile permanent-magnet steel hub driven motor, its technology contents is:
Electric vehicle invisible magnetic pole and tile permanent-magnet steel hub driven motor by drive end bearing bracket, rear end cap, hub-type casing, rotor,
Stator, stator support, axle form, it is characterised in that: hub driven motor rotor is combination type magnetic pole and hidden magnetic pole rotor；
Combination type magnetic pole and hidden magnetic pole rotor are by rectangle permanent-magnet steel, tile permanent-magnet steel, rotor core, hub-type casing, fan ring
Shape forms every magnetic air gap, rotor core is evenly equipped with even number and runs through the radial direction rectangular channel of rotor core thickness, radially rectangular channel
The inner and the inner circle of rotor core between do not connect, be provided with in the outer end of each radial direction rectangular channel and run through rotor core thickness
Fan annular connects every the outer end of the inner of magnetic air gap with radially rectangular channel every magnetic air gap, fan annular, and fan annular is outside magnetic air gap
Not connecting between end and the cylindrical of rotor core, adjacent fan annular does not connects every magnetic air gap, sets every two radial direction rectangular channels
There are the inner arc surface the running through rotor core thickness arc-shaped slot towards rotor core inner circle and arc-shaped slot at adjacent two
The centre that radially rectangular channel is inner, arc-shaped slot does not connects with radially rectangular channel, and the inner of arc-shaped slot is interior with rotor punching
Circle does not connects, by two footpaths of the arc-shaped slot both sides that identical two panels rectangle permanent-magnet steel is respectively placed on rotor core
In rectangular channel and the relative side polarity of two panels rectangle permanent-magnet steel is N pole, then tile permanent-magnet steel is pressed inner arc surface pole
Property is that the mode of N pole is placed in arc-shaped slot, adjacent S pole and S extremely relative to the S pole of two panels rectangle permanent-magnet steel and tile forever
The S of magnet steel the most all by rotor core guide to S pole and S extremely relative to two panels rectangle permanent-magnet steel mid portion rotor core on,
Forming the S pole of hidden magnetic pole, rotor core is fixed in the inner circle of hub-type casing.
Operation principle: when permanent magnetism hub driven motor is passed through by three-phase inverter after the three-phase alternating current of pulsewidth modulation,
Hub driven motor stator produces a space rotating magnetic field, and it is magnetic field interaction, rotor produced by with rotor permanent magnet steel
Produce the rotating torques consistent with stator winding rotating excitation field direction, make hub driven motor p-m rotor rotate, and then drive
Electric automobile runs.
Compared with prior art, rectangle permanent-magnet steel is embedded in radially rectangular channel, tile permanent-magnet steel and is embedded in circular arc the present invention
In shape groove, hub driven motor rotor field is provided by permanent-magnet steel, and this structure is rotor magnetic bypass structure, it is possible to effectively prevent forever
The problem that magnet steel produces irreversible demagnetization under the armature-reaction effect of dash current, it is ensured that permanent-magnet steel not loss of excitation, and without electricity
Exciting Windings for Transverse Differential Protection, power consumption are few, non-carbonate and mechanical commutator, failure rate is low, compact conformation, reliable operation.
