Abstract
The utility model discloses a permanent magnet generator for micro electric vehicles. The permanent magnet generator comprises two main parts, i.e. a rotor and a stator, wherein the rotor is composed of a rotor shell, a rotor flange disc, a magnetic steel holding frame and magnetic steel; the stator is composed of a stator core which is formed by overlapping silicon steel punched sheets, an armature winding and a plastic insulation layer; the permanent magnet generator is characterized in that the stator is a three-phase 30 groove and the rotor is a corresponding 10 antipode. According to the permanent magnet generator, the voltage drop of a motor output voltage from no-load to full-load is less than 20%, and the requirements on power supply and battery recharge for running of electric vehicles can be met without voltage regulation.
Description
Technical field
The utility model relates to the improvement technology of electric motor car, relates in particular to the improvement of two-wheeled, three-wheel mini electric vehicle dynamical system, particularly to the improvement of the generator that carries.
Background technology
Energy-conserving and environment-protective are themes of the world today, so electric motor car arises at the historic moment.Electric motor car is supplied power to motor by vehicle-mounted storage battery, and it is low, pollution-free to have energy consumption, so obtained great popularization and use.The electronic two-wheeled of selling in the market, tricycle use rechargeable batteries such as plumbic acid, ni-mh, lithium ion as power supply, receive the restriction of battery capacity, and distance travelled is limited.For this reason, minitype gas dynamotor of configuration in electric motor car in the driving process, if when the storage battery electric energy is not enough, starts minitype gas dynamotor, is charge in batteries, and electric energy is provided for electric vehicle running.The needs of machine coiling 7 pairs of pole magneto generators commonly used when common compact multi-level permanent magnet generator is manufacturing, this generator output pressure drop is big, controls as if not installing voltage-regulation additional, can not finely satisfy the needs of electric vehicle running power supply and charge in batteries.
Summary of the invention
Compact multi-level permanent magnet generator pressure drop on the existing mini electric vehicle is big, need carry out the problem of voltage-regulation, and the utility model provides a kind of pressure drop little permanent magnet generator.
The permanent magnet generator that is used for mini electric vehicle that the utility model provides; Comprise rotor and stator two large divisions; Rotor is made up of rotor case, rotor flange dish, magnet steel retainer and magnet steel; The stator core that stator is overlapped into by silicon steel punching, armature winding and plastic insulating layer constitute, and it is characterized in that: said stator is three-phase 30 grooves; Said rotor is 10 pairs of corresponding utmost points.
Said magnet steel is a rare earth magnetic steel, and totally 20,20 rare earth magnetic steels evenly are adhesive in the rotor case circle by the spaced mode of south poles and are located by the magnet steel retainer.The magnet steel retainer is adhesive in circle in the rotor case equally.
Said plastic insulating layer is formed in the stator core with the integral molded plastic mode.Also can first machine-shaping is split type again be installed in the stator core.
The good effect of the utility model is:
Unloaded to being fully loaded with the pressure drop of motor output voltage less than 20%, need not carry out the needs that voltage-regulation just is well positioned to meet electric vehicle running power supply and charge in batteries.
Description of drawings
Fig. 1 the utility model structural representation.

Embodiment
Below in conjunction with specific embodiment the utility model is done further explain.
As shown in Figure 1, a kind of permanent magnet generator that is used for mini electric vehicle is made up of stator and rotor two large divisions.Said stator is 10 pairs of utmost points of three-phase, totally 30 grooves; Said rotor is 10 pairs of corresponding utmost points.Rotor is made up of rotor case 1, rotor flange dish 4, magnet steel retainer 2, magnet steel 3; Rotor case 1 is processed by the steel plate stretch process; Rotor case 1 and rotor flange dish 4 formation that rivets together; The even gluing 20 spaced rare earth magnetic steels of south poles of circle in the rotor case 1, magnet steel retainer 2 is adhesive in the round location that is used for magnet steel in the rotor case 1 equally.The stator core 5 that stator is overlapped into by silicon steel punching, armature winding 6 and plastic insulating layer 7 constitute.
As shown in Figure 2, the silicon steel punching of forming stator core 5 has 30 grooves.In stator core 5, form plastic insulating layer 7 by the integral molded plastic mode, also split type plastic insulating layer 7 can be installed in stator core 5.
The foregoing description of the utility model only is to give an example for what explanation the utility model was done, and is not to be the qualification to the execution mode of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation and changes, can't give exhaustive to all execution modes here; Conspicuous variation that every technical scheme that belongs to the utility model is amplified out or change still are in the row of the protection range of the utility model.
