Technical field
The utility model belongs to the pure electric automobile motor; It is to adopt on the R13-R17 pure electric automobile that the utility model relates to a kind of trailing wheel; The permanent-magnet DC brushless wheel hub motor that efficient is high, the controller that it is complementary with it, battery constitute the dynamical system of pure electric automobile and minicar jointly.
Background technology
Current, the prior fuel oil automobile is all wanted to be used for to substitute to the input great amount of manpower and material resources of electric automobile in countries in the world, to reach energy savings, reduces the purpose of discharging.
But traditional electric automobile generally adopts the middle motor, and voltage is between 300-350V, though the speed of a motor vehicle can satisfy basic demand; But cost, especially manufacturing cost are extremely expensive, are difficult to accepted by the consumer; The charging problem in the use that adds is difficult to solve, and still is difficult to so far popularize.
In China, situation about being faced is more severe, and is well-known; China's population accounts for 20% of the world, but oil reserve only accounts for 2.8% of the world, adds society and rapid development of economy; Demand to oil is bigger, and " with electricity generation oil " energy-saving and emission-reduction have become the government and the common people's common recognition.
Summary of the invention
To the existing problem of background technology; The utility model provides a kind of novel pure electric automobile efficient permanent magnet brush DC wheel hub motor; Can directly be installed on the pure electric automobile that trailing wheel is R13-R17; It is little to have the electric current of going, and speed is fast, and manufacturing cost and use cost all is significantly less than the advantage of the pure electric automobile of releasing the our times various countries.
For achieving the above object, the utility model is achieved through following technical scheme: a kind of pure electric automobile efficient permanent magnet brush DC wheel hub motor, its motor adopts three-phase, 46 utmost points, 51 groove structures.Structure comprises a wheel hub, and the middle part of wheel hub is provided with bearing, the sheathed motor shaft in the inside of bearing; Motor shaft is surrounded with coil in the periphery, and the coil side is adjacent cored, and iron core is secured on the motor shaft through support; The surperficial coaxial rings of coil is covered with the limit lid, and the limit lid is formed by connecting on left side lid and the right lid, and the front end of left side lid and wheel hub hold and join; The rear end of left side lid and the right fastening linking to each other of lid; The rear end riveted joint of the right lid has brake(-holder) block, and left side lid is fastened with magnet steel with the junction of the right lid, and magnet steel is corresponding with the coil level.
The further technical measures of the utility model are, the coil in stating is circumscribed with one and is used for the electric wire that links to each other with controller; Magnet steel is selected the rare-earth Nd-Fe-B 38st material manufacture of good magnetic for use, significantly promotes performance, and it highly is 80-140mm, and thickness is 4-8mm; Iron core adopts 35W300 or 50W310 not to have the orientation cold drawing, and its coil adopts the star winding method of innovation.
The present invention adopts the brush DC hub-type directly to drive, and manufacturing cost is lower than the middle motor, and voltage is 216V; Have only the former 2/3rds, thus the battery of coupling can than middle lack 1/3rd, owing to being direct drive electric motor; Unlike middle will be through gear reduction consumed power several times, so efficient is high, it is corresponding also little to exercise electric current; Under equal conditions, manufacturing cost is economized over half, and use cost has only 60% of mid-motor.
With regard to the motor of dynamical system, controller and battery manufacturing cost and use cost all have only about 2/3rds of mid-motor, and need not build charging pile; Adopt existing power supply; Basically can satisfy the demand of charging, be convenient to promote, accepted by the consumer easily.
Reduce toxic emission, the protection environment, energy savings and expenditure, it is little to have an electric current of going, the advantage of battery long service life, can install or be retrofitted in trailing wheel is on all kinds of cars and minicar of R13-R17, wide application.
