Abstract
The utility model relates to a direct current motor for electric autobicycles and electric power assist vehicles, which aims to solve the motor structure technology. The utility model discloses a boss-type rare-earth permanent-magnet motor, which adopts the structure of a rotary motor shell and comprises a rotary external rotor component and a fixed internal rotor component. The utility model is characterized in that the shell comprises a boss, a spoke and a circular rim, which are integrated into one body, wherein the inner diameter of the boss tightly matches the outer diameter of the external rotor, the outer diameter of the boss and inner diameter of the circular rim with a U-shaped lateral section form an integrated body by the radial ring-shape spoke, a tyre tightly wraps inside a U-shaped groove to combine the motor and the tyre into an integrated body to further form an independent drive wheel. The drive wheel can be used by assembling the drive wheel on an electric autobicycle or an electric power assist vehicle. The utility model can also be applied in electric vehicles such as electric automobiles, electric vehicles for the disabled, and the like.
Description
Technical field
The utility model relates to DC motor, specifically is used for the electrical motor on battery-operated motor cycle, the electric moving aid vehicle.
Background technology
With motor bike, the mini-motorcycle that fuel oil is used as power, its defective is their a large amount of exhaust emissions and noises, seriously pollute and affect environment, and be the problem that people pay close attention to.It two is that they need mechanical transmission mechanism and mechanical speed change mechanism, therefore, complex structure, waste of power is big, and engine efficiency is low, poor reliability.In order to protect environment, raise the efficiency, Chinese patent CN2316763Y discloses " wheel shell-type permanent magnet DC motor ", and this motor can only be contained on the bicycle, loads onto storage battery and has become Electrical Bicycle.Because this motor is a wheel shell-type structure, can not adorn usefulness on battery-operated motor cycle and electric moving aid vehicle, fail to pay in practicality.In addition, magnet steel in this motor stator and magnetizer adopt adhesive method, and magnet steel comes off easily like this, influences the horsepower output of motor, even causes the unexpected stall of motor, causes traffic accident.
Summary of the invention
The utility model provides a kind of hub-type rare-earth permanent magnet motor for solving the electric motor structure technology of battery-operated motor cycle, electric moving aid vehicle, and it can improve motor efficiency effectively, reduces noise, improves air environment.
The utility model is to realize by following technical scheme, and it comprises outer rotor assembly and fixing internal stator assembly two parts of hub-type rotation, and the outer rotor assembly comprises casing, outer rotor, wheel cap, commutator; The internal stator assembly comprises axle, carbon-brush holder, carbon brush, magnetizer, magnet steel, its structural feature is that casing is by wheel hub, spoke, wheel rim three part integrators, the internal diameter of above-mentioned wheel hub and the external diameter of outer rotor are flush fit, and the external diameter and the cross-sectional plane of wheel hub is the wheel rim internal diameter of " U " type shape integral body of spoke formation by annular radial.
Magnet steel is connected by the countersunk head screw with magnetizer.
The utility model changes over the hub-type structure that is made of one wheel hub, spoke, wheel rim with motor casing by the wheel shell-type, wrap tire on the wheel rim after, become an independent wheel, be suitable on battery-operated motor cycle and the electric moving aid vehicle direct mount to use.Substitute oil-fired vehicle with battery-driven car, simple in structure, be easy to popularize.Adopt the countersunk head screw to tighten up magnet steel and magnetizer, improve motor performance, improved motor efficiency, improve serviceability, increase the service life, improve air environment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below with reference to the embodiment of accompanying drawing, the utility model is described in further detail.
Among Fig. 1, the casing of this electrical motor is made one by wheel hub 6, spoke 7, wheel rim 1, and present embodiment adopts hydronalium die casting to form.Outer rotor 8 comprises coil and iron core, and the iron core external diameter of wheel hub 6 internal diameters and outer rotor 8 is linked to be same swivel by flush fit.The inner ring of wheel hub 6 peripheries and wheel rim 1 is made one by annular radial spoke 7.The cross-sectional plane of wheel rim 1 is " U " type shape, and tire wraps tightly at this in " U " type groove.Commutator 4 and wheel cap 12 are connected with casing by screw respectively.When motor connecting power, the outer rotor 8 of electrical motor drives casing and tire turns round together.The two ends of axle 3 are fastened on the vehicle frame of battery-driven car with jam nut respectively.Carbon-brush holder 2 tightly is enclosed within on the external diameter of axle 3, and carbon brush 5 is installed in the carbon brush hole of carbon-brush holder 2, and is moving contact with commutator 4.The internal diameter of the external diameter of carbon-brush holder 2 and magnetizer 11 is injection molded into one, and magnet steel 10 is close on the magnetizer 11, and tightens up mutually by countersunk head screw 9, comes off to avoid magnet steel, and the material of present embodiment magnet steel is a thulium permanent magnet.Present embodiment adopts the 48V vdc, after the input, output power of motor is 1500W, nominal load current is less than 39A, the motor bike speed per hour is 55Km/h, and rated output torque is greater than 20N-m, and specified temperature rise is lower than 70 ℃, present embodiment can be contained on the electric moving aid vehicle of the battery-operated motor cycle of 50-55Km/h and 30-35Km/h and use, and motor efficiency reaches 85%.Casing structure design of the present utility model makes motor, tire in one, becomes the driving wheel of an independent tape spool, is installed on battery-operated motor cycle, the electric moving aid vehicle, can use, and can also be used for elec. vehicles such as electronlmobil, electronic tricycle for the disabled.
Claims (2)
