Abstract
The utility model discloses a wheel hub motor, comprising a rotor and a stator; wherein the rotor is positioned in the stator and the rotor is composed of an iron core wound by a winding; the stator comprises a casing, and ten sheets of permanent magnet are arranged inside the casing. The included angle between two adjacent permanent magnets is relatively small; the end of the winding wound on a silicon steel sheet is relatively small; the resistance of the winding is relatively small and the copper loss is also relatively small; thus the utility model improves the efficiency of the wheel hub motor by 5%, and can be used as the wheel hub motor of the electric bicycle.
Description
The utility model relates to a kind of wheel hub motor of electric bicycle.
Chinese patent ZL9323526.7 discloses a kind of electric wheel ring motor.This motor comprises stator and rotor, and rotor is positioned at stator, and rotor is stacked and be wound with coil and constitute by thin silicon steel sheet, and the inwall of stator is connected with 8 permanent magnets.Because number of magnetic poles is less, thereby the angle between the permanent magnet is bigger, causes on the silicon steel sheet end of winding longer, and the resistance of winding is also big, and copper loss is also big, and consequently the efficient of wheel hub motor is lower.Because therefore the entrained limited energy of electric bicycle will prolong the once distance travelled of charging, just must improve the efficient of wheel hub motor as far as possible.
The purpose of this utility model is that a kind of wheel hub motor will be provided, and the efficient of this wheel hub motor is higher.
The purpose of this utility model is achieved in that this wheel hub motor comprises rotor and stator, and rotor is positioned at stator, and rotor is made of the iron core that is wound with winding, and stator comprises casing, and the casing inboard is connected with ten permanent magnets.
According to increasing the principle that number of magnetic poles can reduce winding overhang length, suitably increase number of magnetic poles, just can reduce winding resistance, reduce the winding copper loss, also just can improve electric efficiency.Increase the restriction that number of magnetic poles is subjected to commutator segment and brush width.According to result of the test, the number of magnetic poles of electric bicycle hub motor is best with ten.
The inwall of shell of the present utility model is connected with ten permanent magnets, thereby the angle between the adjacent permanent is less, the end of winding is also less on the silicon steel sheet, the resistance of winding is also less, copper loss is also less, consequently improved the efficient of wheel hub motor, efficient improves can reach five percentage points.The wheel hub motor that can be used as electric bicycle uses.
Below in conjunction with drawings and Examples the utility model is elaborated.
Accompanying drawing is the structure chart of an embodiment of the present utility model.
1. casings among the figure, 2. permanent magnet, 3. iron core, 4. winding, 5. spool.
In the embodiment shown in the figures, rotor is positioned at stator, and rotor is made of the iron core 3 that is wound with winding 4, and stator comprises casing 1, and casing 1 inboard is connected with ten permanent magnets 2.The length of winding 4 ends is substantially equal to the length of adjacent permanent 2 angles, number of poles for a long time, the end shortens naturally.
