Description
Technical field
The utility model belongs to hub motor technical field, more particularly to a kind of brushless DC hub-motor.
Background technique
Electric vehicle is using the assembly for the vehicle for being driven by electricity traveling, and most commonly seen electric vehicle is to be driven using electric power merely
Dynamic battery-operated motor cycle.Electric vehicle generallys use In-wheel motor driving, due to the performance difference of hub motor, so that electric vehicle
Power, travel speed and bearing capacity are all not quite similar.
Currently, more commonly used hub motor is DC brushless motor, with long service life, installation maintenance it is easy,
The advantages of power saving, inner main component are rotor and stator, and stator is mounted on hind axle, outer spacer cartridge rotor, are turned
The outer rim and rear-wheel hub integrally connected of son, radial equipartition installs multiple permanent magnets on the inner edge of rotor, multiple permanent magnet
Alternating polarity setting, the stator outer rim radial equipartition opposite with permanent magnet produce multiple salient poles for coiling winding, and each two
It is pole slot between a adjacent salient pole.
It is more typical for 36-51 stator slot on 46-48 permanent magnet on rotor, stator, existing structure in the prior art
Rotor and stator cooperation, deposit that temperature at work is higher, and noise is big, the defects of electric current when work is big, existing wheel hub electricity
Son is unfavorable for the raising of electric vehicle accelerating ability and mileage travelled.
Summary of the invention
The utility model is to solve technical problem present in well-known technique and provide one kind and improve low regime and high speed
The efficiency in area, electric current when work are lower than conventional motors, and motor noise is small, peak efficiency and torque capacity are big, is conducive to electricity
A kind of brushless DC hub-motor of motor-car accelerating ability and mileage travelled.
The utility model is adopted the technical scheme that solve technical problem present in well-known technique:
A kind of brushless DC hub-motor, including rotor and stator, rotor intervals are sleeved on stator outer circle, in rotor inner circle
Radial equipartition installs multiple permanent magnets, and the stator includes stator core 2-1 and bracket 2-2, it is characterised in that: on the rotor
The permanent magnet of installation is 52, and permanent magnet is with a thickness of 1.8-2.0mm；The stator core inner hole is 164-165mm；The stator
The outer diameter of iron core is 207-208mm, and the stator slot on stator core is 48, and the width of rebate L1 of stator core is 2.0-
3.0mm, the width L2-L3 of the stator tooth of the stator are 7-12mm.
The utility model has the advantages and positive effects of: the utility model passes through certain amount of stator slot and permanent magnetism
Body cooperates, and improves the efficiency of low regime and high velocity, and electric current when work is lower than conventional motors, peak efficiency and maximum
Torque is all larger than conventional motors, and efficiency platform when work is forward, is suitable for northern small-power and moves motor, is conducive to electric vehicle and adds
The raising of fast performance and mileage travelled, motor noise when riding also very little.It is higher than traditional product cost performance.
