Background technology
In known technical field, the drive motors of Moped Scooter in the market, its peak efficiency 78%, its shelf-life is 2 years, because its structure mostly has been brush or has had Hall element and a reduction gearing etc., the wearing and tearing of these components and parts during due to work, cause delivery efficiency to decline on the one hand, also can produce on the other hand noise, cause the life-span to decline simultaneously; In addition the speed governing of common DC motor be by single, directly change curtage and realize, therefore, under the different speed of a motor vehicle of Moped Scooter require, drive motors cannot remain on the work of efficient district, electric integrated utilization ratio is low.Cause for above-mentioned reasons that motor volume is relatively large, efficiency is relatively low, work noise is large, reliability is low, the life-span is short.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, a kind of electric boosted automobile-used small-sized drive motors is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of electric boosted automobile-used small-sized drive motors, comprise the electric machine casing of both ends open and hollow, all be mounted by means of screws with motor lid and form installation cavity at the opening two ends of described electric machine casing, center at described installation cavity is provided with motor shaft, between described motor shaft and motor lid, be provided with bearing, centered by the central axis of described motor shaft, be provided with several electromagnet and form rotor at the inner surface of electric machine casing, it is characterized in that: on described motor shaft, and be positioned at and cavity is installed is " one " font and is arranged with in turn three silicon steel sheet groups, in each silicon steel group, be all wound with several coiling groups, and in the region of the coiling group in each silicon steel group between adjacent silicon steel group, being shape straggly distributes, and each silicon steel group is electrically connected to carry out the control of size of current respectively with independent control circuit.
The beneficial effects of the utility model are: the utility model is simple in structure, rationally, for existing problems in technical background, solve one by one.Do not use in design the components and parts such as brush and reduction gearing of easy to wear and easy inefficacy, take into full account the Performance Match of electromagnetic circuit and winding, on the basis of cancelling Hall element, be optimized and calculate and design, do not adopt merely and carry out speed governing by the mode that changes electric current and voltage, but export and pass through control switching circuit constant in the situation that at energy, thereby change magnetic field to carry out macroscopical speed governing, thereby can realize the efficiency operation under the various speed of a motor vehicle require, it is little that overall performance has been realized volume, lightweight, low noise, peak efficiency can rise to 84%, life-span can extend to 8 years, Moped Scooter can be realized the continual mileages that once charging is travelled more than 85 kilometers.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1. motor lid, 2. electric machine casing, 3. screw, 4. motor shaft, 5. silicon steel sheet group, 6. coiling group, 7. bearing, 8. motor shaft.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The preferred embodiment of the electric boosted automobile-used small-sized drive motors of the utility model as shown in Figure 1, comprise the electric machine casing 2 of both ends open and hollow, all be installed with motor lid 1 by screw 3 at the opening two ends of described electric machine casing 2 and form installation cavity, be provided with motor shaft 8 at the center of described installation cavity, between described motor shaft 4 and motor lid 1, be provided with bearing 7, centered by the central axis of described motor shaft 8, be provided with several electromagnet 4 and form rotor at the inner surface of electric machine casing 2, it is characterized in that: on described motor shaft 8, and be positioned at and cavity is installed is " one " font and is arranged with in turn three silicon steel sheet groups 5, in each silicon steel group 5, be all wound with several coiling groups 6, and in the region of the coiling group 6 in each silicon steel group 5 between adjacent silicon steel group 5, being shape straggly distributes, and each silicon steel group 5 is electrically connected to carry out the control of size of current respectively with independent control circuit.
Because this motor has individual winding, in the time of machine operation according to different rotating speeds and torque-demand, for example at startup, level road low speed driving, run at high speed, climb, under the different operating mode demands such as acceleration, deceleration, braking, according to the control and management strategy pre-establishing, respectively the winding of different pairs is applied to different electric currents and voltage, guarantee that motor all the time can be in the work of efficient district, carry out indirect speed governing by changing magnetic field, reduce the frictional dissipation of structural member, and in deceleration and brake situation, can provide reverse current to reclaim for braking and energy.
Control strategy in this programme is as follows: when startup and low speed climbing, adopt many windings co-operation pattern, realize little electric current high pulling torque; When level road low speed driving, adopt simplex winding mode of operation, energy saving; When running at high speed and rushing slope fast, adopt double winding mode of operation; When acceleration, adopt many windings mode of operation; When braking, generate electricity with one group of winding wherein.
The utility model is simple in structure, adds up to rationally, for existing problems in technical background, solves one by one.Do not use in design the components and parts such as brush and reduction gearing of easy to wear and easy inefficacy, take into full account the Performance Match of electromagnetic circuit and winding, on the basis of cancelling Hall element, be optimized and calculate and design, do not adopt merely and carry out speed governing by the mode that changes electric current and voltage, but export constant in the situation that by the electric current of the independent control circuit of conversion at energy, thereby change magnetic field to carry out macroscopical speed governing, thereby can realize the efficiency operation under the various speed of a motor vehicle require, it is little that overall performance has been realized volume, lightweight, low noise, peak efficiency can rise to 84%, life-span can extend to 8 years, Moped Scooter can be realized the continual mileages that once charging is travelled more than 85 kilometers.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.
