Description
Technical field
The utility model is related to a kind of electric bicycle motor, the public p-m rotor electricity of the electric bicycle especially climbed
Machine.
Background technology
Electric bicycle motor is had at present, is all a motor driving, there are 36 overhead accumulator power supplys to power, this car is put down
Road traveling is also possible that but climbing can slow down, and speed owes fast deficiency, and also useful 48 volts are powered, and the big climbing of driving force is also easy, but
There is the big deficiency of the high weight of cost.
The content of the invention
In order to overcome above-mentioned electric bicycle motor to exist, climbing is difficult, and the high deficiency of the big cost of weight is of the present utility model
Purpose provides one kind and climbed, the lightweight public permanent-magnet rotor motor of electric bicycle.
The utility model solves the technical scheme that is used of problem：It includes tire, steel ring, permanent magnet, armature winding
Plate, aluminium dish, axle, bearing, sensor, the cylindrical connection tire of steel ring, steel ring centre bore are connected with axle with bearing, the side of steel ring former two
8 blocks of staggeredly uniform permanent magnets for configuring N, S polarity are connected respectively, constitute respectively set beside public p-m rotor, 8 block permanent magnets together
There is one block of armature winding plate, 0.5mm air gaps are provided between permanent magnet and armature winding plate, the side correspondence position per block permanent magnet
Labyrinth shape planar line is made into 0.5mm thickness copper foil wide 2mm with copper foil plate acid etching provided with a coil, coil in armature winding plate
Circle, 8 coils are just rewinding to interconnected and are being connected into armature winding together, and armature winding plate is fixed in aluminium dish constitutes nothing together
Stator unshakable in one's determination, aluminium dish is fixed on axle, and sensor is beside permanent magnet, public p-m rotor and the stator composition two of two sides two
Motor.Because there is two motors, being powered also with 36 volts has output power to climb, and this motor does not have iron core, and weight is just
Gently, so as to reach that the utility model is climbed, lightweight purpose.
The beneficial effects of the utility model be climb, it is lightweight, cost is just low.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 Fig. 2 is the mutual profile of the utility model embodiment A-A, B-B.
1, tire 2, steel ring 3, permanent magnet 4, armature winding plate 5, aluminium dish 6, bearing 7, axle 8, sensor in figure
Embodiment
In the embodiment shown in Fig. 1,2, the cylindrical connection tire 1 of steel ring 2, the centre bore of steel ring 2 bearing 6 and the activity of axle 7
Connection, the side of 2 former of steel ring two connects 8 pieces and staggeredly uniformly configures the side of 3,8 block permanent magnet of permanent magnet 3 of N, S polarity respectively respectively
Provided with one block of armature winding plate 4, armature winding plate 4 is connected with the thick sheet coppers of 0.5mm and 5mm heavy sheet glass steel plate, is formed through acid etching.
0.5mm air gaps are provided between permanent magnet 3 and armature plate composition 4.It is provided with per the armature winding plate 4 of the correspondence position of block permanent magnet 3
Labyrinth shape planar coil is made into 0.5mm thickness copper foil wide 2mm with copper foil plate acid etching in one coil, coil, and 8 coils are just
Rewind to interconnected and be connected into armature winding, armature winding plate 4, which is bonded in aluminium dish 5, is combined into stator without iron core, and aluminium dish 5 is fixed
On axle 7.Sensor 8 measures pole polarity mounted in the side of permanent magnet 3 and goes control commutating circuit plate to give armature winding supplying DC
Electricity, makes coil produce the polarity generation repulsion identical with the polarity of permanent magnet 3 in magnetic field, drive rotor rotation.This motor is using public
The stator combination of permanent magnet rotary and two sides drives simultaneously into two motors, and wheel has power big, and climbing capacity is strong, also because not having
The cored low advantage of lightweight, cost.
