Abstract
This invention relates to one electrical bicycle low speed motor, which adds inner rotor in motor and clutch between inner and outer rotors, wherein, the clutch is fixed on the outer rotor supported on the axis six through axis bear five; when riding, the rotation adjustor motor works with inner rotor work to drive it move through clutch three and outer rotor two; when loosing gear, motor stops and the clutch three removes with only outer rotor move without impact from absorption to realize moving without resistance.
Description
Technical field:
The invention belongs to the electric bicycle motor class, particularly relate to and a kind ofly have that undamped slides, Remarkable Energy Saving electric bicycle slow-speed motor.
Background technology:
As everyone knows, the electric bicycle motor on the present market can be divided into two big classes: a class is to slow down by gear drive to drive the high-speed permanent magnetic direct current machine that has brush; Another kind of is directly to drive rotating speed less than 1000 rev/mins low-speed permanent-magnet direct current motor, this motor is divided into again two kinds of brush permanent magnet DC motor and brushless permanent magnet DC motors, existing electric vehicle motor all adopts magneto, though it has efficient height, advantage that volume is little.But because its magnetic pole all adopts permanent magnetic material (as ferrite, neodymium iron boron etc.), has very strong suction, under the idle situation of motor, need just can make rotor rotation with very big power, again because rotator inertia is little, and make electric motor car motor in the process of riding need running continuously, when motor quit work, the electric motor vehicle sliding ability was so power consumption is big, shorten the mileages of continuation of electric motor car greatly, shortened the useful life of motor simultaneously.
Summary of the invention:
Main purpose of the present invention is to overcome above deficiency and provides a kind of has that undamped slides and Remarkable Energy Saving electric bicycle slow-speed motor.
The technical solution adopted for the present invention to solve the technical problems is: it is made up of stator, rotor and axle, it is characterized in that: increase is not subjected to the external rotor 2 of magnetic pole suction affects outside motor internal rotor 1, between inside and outside rotor 1,2, have clutch 3, clutch 3 usefulness screws 4 are fixed on the external rotor 2, and external rotor 2 is supported on the bearing 6 by axle 5.
The present invention can also adopt following technical scheme: described motor is that low speed has the brush motor, also can be the low speed brushless machine.
Advantage and good effect that the present invention has are: because increased external rotor 2 and clutch 3, so, inside and outside rotor 1,2 moves respectively, make electric motor car have wheel function, its effect has surpassed the road speed of ordinary bicycle, and having significantly reduced power consumption, the electric motor car mileages of continuation also can increase more than 20%.
Description of drawings:
Fig. 1 is the structural representation of low-speed motor for electric bicycle.
Among Fig. 1: 1. internal rotor, 2. external rotor, 3. clutch, 4. screw, 5. spool, 6. bearing.
Embodiment:
For further understanding summary of the invention characteristics of the present invention and effect following examples for example now, and conjunction with figs. is described in detail as follows, and sees also Fig. 1.
As shown in Figure 1: low-speed motor for electric bicycle is by internal rotor 1, external rotor 2, clutch 3, screw 4, axle 5 and bearing 6 are formed, because, increase is not subjected to the external rotor 2 of the influence of magnetic pole suction outside motor internal rotor 1, interior, external rotor 1, come transfer torque with clutch 3 between 2, clutch 3 usefulness screws 4 are fixed on the external rotor 2, external rotor 2 is supported on the bearing 6 by axle 5, when riding electric motor car, rotate the speed regulator on the handlebar, machine operation then, internal rotor 1 rotates, and drives external rotor 2 and rotates and drive electric motor car and advance by being fixed on clutch 3 on the external rotor 2; When the speed regulator that unclamps on the handlebar, motor is not worked, and clutch 3 is thrown off, have only external rotor 2 to rotate, because external rotor 2 is not subjected to the influence of magnetic pole suction, 2 of external rotors rotate by inertia on the bearing 6 at two ends, at this moment, external rotor 2 rotates very flexible, thereby makes electric motor car have wheel function, has realized that promptly undamped slides, its effect has surpassed common bicycle, reduced power consumption, simultaneously, the electric motor car mileages of continuation can increase more than 20%.The present invention can be used for low speed to be had on the brush motor, also can be used on the low speed brushless machine.Its advantage is: but undamped slides, energy-saving effect is remarkable, simple in structure, cost is low.
