In upper table: T represents moment of torsion, unit N.m (ox. rice); N represents rotating speed, unit r/min (rev/min); Pout represents power output, unit W (watt); U represents voltage, unit V (volt); I represents electric current, unit A (peace); Pin represents input power, unit W (watt); Eff represents efficiency, is percentage (%).
General body weight, at about 70kg, needs the moment of torsion of wheel hub motor greatly about 7N.m; Thus, for bicycle wheel motor, output torque is when about 7N.m, and efficiency is more high more energy-conservation, and electric current is lower, then calorimetric of generating heat is little.As seen from the above table, time in the scope that moment of torsion is 5-10N.m, the efficiency of this bicycle wheel motor is 86% ~ 90%, and when moment of torsion is 7N.m, efficiency reaches more than 88.8%, and efficiency is high.In addition, time in the scope that moment of torsion is 5-10N.m, the electric current of this bicycle wheel motor is only 3.474A ~ 6.86A, and when moment of torsion is 7N.m, electric current is only about 5A, the electric current namely needed is less, then the corresponding heat produced is little, also more energy-conservation, and useful life is also longer simultaneously.In addition, as can be seen from upper table also, the starting current of this wheel hub motor is less, easily starts.
Embodiment five:
Refer to Fig. 8, a kind of motor, see also Fig. 1 and Fig. 4, the motor stator 20b that this motor comprises shell (not shown), rotating shaft 41, rotor 42 and coordinates with rotor 42, wherein motor stator 20b is the stator 20b as described in embodiment three.Rotating shaft 41 is articulated on shell, and rotor 42 is arranged in rotating shaft 41, and motor stator 20b matches with rotor 42, and motor stator 20b is fixed on shell.
This motor employs above-mentioned motor stator 20b, compared with existing motor, under same volume, input current, power; The magnetic field intensity that motor stator 20b produces is large, and electromagnetic conversion efficiency is high, and the thrust produced between motor stator 20b and rotor 42 is larger, can produce more high pulling torque, carry larger weight, export more high power, namely improve the efficiency of motor.
Because motor stator 20b can produce stronger magnetic field, then when motor start-up, the starting current of needs is less, more easily starts.Caloric value is little, and accordingly, in motor, temperature is also relatively lower, thus the problem that can better prevent permanent magnet from high temperature demagnetizing occurs, improves the useful life of motor.
In addition, the iron core 11 of the Energizing unit 10 of the motor stator 20b of motor is relatively little, then can reduce the gravitation of permanent magnets 423 pairs of iron cores 11, and then reduce when the magnetic field intensity of permanent magnets 423 is larger, strong magnetic reduces the impact of power consumption efficiency on the graviational interaction of iron core 11, and then improves the efficiency of motor; Can also iron loss be reduced simultaneously, and then reduce the caloric value of Energizing unit 10.
Particularly, rotor 42 comprises the bracing frame 421 be installed in rotating shaft 41, is fixed on the locating ring 422 on bracing frame 421 and is arranged on some permanent magnets 423 of opposite exterior lateral sides of locating ring 422.Some permanent magnets 423 are the alternate setting of south poles, and namely in these permanent magnets 423, the magnetic pole of another permanent magnets 423 that the magnetic pole of certain permanent magnets 423 is adjacent with this permanent magnets 423 is just contrary arbitrarily.Improve magnetic field utilance, better drive rotor 42 to rotate.
Further, identical with the structural principle of wheel hub rotor 32 in above-described embodiment four, the width of each permanent magnets 423 is close with the thickness of Energizing unit 10, namely the width of each permanent magnets 423 can equal or the thickness of bigger little Energizing unit 10, thus make each permanent magnets 423 can form more multipair magnetic pole with Energizing unit 10, improve magnetic field intensity between motor stator 20b and rotor 42, increase the thrust of motor.
Further, locating ring 422 can be made up of the material such as soft iron or silicon steel, namely locating ring 422 can be soft iron ring or silicon steel ring etc., and permanent magnets 423 is fixed on locating ring 422, thus adjacent two permanent magnets 423 and retainer ring can be made to be formed be similar to U-shaped magnet, improve the magnetic field intensity of rotor 42 generation.On the whole, the rotor 42 of embodiment five and the similar of the wheel hub rotor 32 of embodiment four, no longer burden.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
