Abstract
The utility model provides a driving device of an electric assisted bicycle, and relates to the field of the electric assisted bicycle, in particular to a driving device of the electric assisted bicycle. The driving device comprises a rolling bearing and a motor outer rotary casing. The driving device is characterized in that an arc strip-shaped ND-FE-B permanent magnet is inlaid in the motor outer rotary casing; a static core stator is provided with a magnetism shielding seat on a wheel shaft, and the magnetism shielding seat is provided with three or four assembled iron cores; a coil is arranged outside each iron core, and the middle part of the iron core is a machine shaft. The driving device has the advantages that the structure is simple and reasonable, and can thoroughly solve many defects existing in the winding type motors with middle speed and low speed; the phase matching requirement is saved, so the control part is simplified; the original driving motor is changed, so the driving device has the characteristics of high forming efficiency, little material consumption and convenient manufacture and control; after the driving device is used, the electric consumption of the accumulator is greatly reduced, the electric assisted bicycle can be driven faster and farther, especially reflecting on the front wheel driving, and the driving device is an ideal driving tool for the environment-protection type electric assisted bicycle.
Description
Technical field
The utility model relates to electric power mini-motorcycle field, a kind of specifically actuating device of electric power mini-motorcycle.
Background technology
The existing power mini-motorcycle mostly is back-wheel drive greatly, and attached foot pedal apparatus, so not during starter motor, become the electrical generator state to need very big pedal power by the foot-operated motor that advances of manpower, the patent No. is the technical scheme that the utility model patent of ZL200520042011.2 has proposed a kind of partition type device for this reason, the outer transcapsidation of wheel and motor is separated, solved this problem, efficient is low, consumable big, need expend problems such as more copper, iron material when making but existing slowspeed machine structure still exists.
Summary of the invention
For addressing the aforementioned drawbacks, the utility model provides a kind of new technical scheme, has promoted the structure of existing motor, can address the aforementioned drawbacks the raising efficiency of motor and save nonferrous metal resource greatly by actv..
It is excitatory that the technical solution of the utility model is achieved in that the Nd-Fe-B permanent magnetic magnet that adopts high magnetic flux replaces, and the nd-fe-b permanent magnetic strip of high magnetic flux is installed in the transcapsidation outside the electric power mini-motorcycle, and polarity is inside and outside distribution.For example inner ring is the N utmost point, and the outer ring is the S utmost point.Quiet core stator is established the magnetic cup seat on axletree, four (or three) the copper coils that distribute on the magnetic cup seat, the conducting magnet core that has special geometric form and performance to make up in the coil.To the direct current (DC) that coil is provided with pulsing, press right-handed helix pipe rule, make the iron core outer end produce the N utmost point, with the same polarity principle of repelling each other, form magnetically-actuated like this, improved the efficient of drive motor greatly, structurally kept the characteristics of no wear-out part.
The utility model has the advantages that, simple and reasonable, can thoroughly change in the winding type, slowspeed machine many deficiencies, do not had the requirement of phase matched simultaneously, control has just been simplified, and has changed original drive motor, make the utility model become efficient height, consumptive material few, make and control convenient.
As long as matching function f (x)=Lf during design can realize.
