Abstract
The utility model relates to a three phase AC magnetor arranged on motorcycle engines, comprising a rotor namely a fly wheel 1, a stator 2, a trigger 3, a bunch 4, a lining sleeve 5 and a protecting cover 6. The main technical proposal is that the rotor namely the fly wheel adopts eight-pole magnetic steel, the stator 2 adopts an eleven-pole coil winding. The generated three-phase AC can enhance the electrical generating power of the motorcycle engines via full wave rectification so as to satisfy electric energy supplement of an accumulator 9 after discharging, and the electric starting performance of the motorcycles can be increased. Meanwhile, the brightness of lighting head lamps 10 can not be affected by the revolution speed of the motorcycle engines, and the safety of night running of the motorcycles can be assured.
Description
The utility model relates to a kind of three-phase alternating current magneto that is installed on the motorcycle engine, for motorcycle provides battery charge power supply and mains lighting supply.
The electricity starting motorcycle of domestic production at present, magneto on its engine is the single phase alternating current (A.C.) magneto, generated output is low, motorcycle to the electricity starting has following influence: one, to the motorcycle battery undercharge, can not in time replenish after the electric power storage ground over-discharge can, damage storage battery easily, make electric starting performance descend starting difficulty; Its two, the motorcycle lighting headlight is directly powered by magneto, lamplight brightness changes with the height of engine speed, lamplight brightness is very dark during low speed, influence illumination, night running is absolutely unsafe.
Three-phase alternating current magneto described in the utility model is not found in the prior art as yet.
The purpose of this utility model provides a kind of three-phase alternating current magneto that is installed on the motorcycle engine, the generated output of engine is improved, the electric energy that satisfies after storage battery frequently discharges replenishes, improved the electric starting performance of motorcycle, the brightness of lighting headlight simultaneously is not subjected to the influence of engine speed, has ensured the fail safe of motorcycle at the low speed driving at night.
In order to achieve the above object, the solution that the utility model adopts is: single-phase magneto rotor be flywheel to change four utmost point magnet steel be ends of the earth magnet steel, it is 11 polar curve circle windings that stator changes the quadrupole coil winding.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the utility model three-phase alternating current magneto elevation cross-sectional view.
Fig. 2 is the utility model three-phase alternating current magneto end view.
Fig. 3 is that the utility model three-phase alternating current magneto is installed in the line map on the motorcycle engine.
As seen from Figure 1, Figure 2, the structure of the utility model three-phase alternating current magneto comprises: rotor is flywheel 1, stator 2, trigger 3, wire harness 4, lining 5, guard shield 6.Rotor is that flywheel 1 is ends of the earth magnet steel, promptly adopts four blocks of magnet that are tile, and each piece magnet a pair of utmost point that charges is the ends of the earth, is that to make rotor be that flywheel 1 is connected with engine crankshaft for the cam taper hole of flywheel 1 by rotor.Stator 2 is made up of coil windings and stator core, and stator 2 adopts 11 polar curve circle windings, wherein has nine polar curve circle windings to be wrapped in the stator core with the thicker enamelled wire of diameter, and three groups (utmost points) are a phase, are three-phase; There are two polar curve circle windings to be wrapped in the stator core in addition, to supply with igniter 11 energy with thinner enamelled wire.Stator 2 and trigger 3 are fixedly mounted on respectively that engine is left front to cover, and maintenance and rotor are that flywheel 1 has certain physical dimension.Trigger 3 is connected on the wire harness 4.Wire harness 4 is made up of seven gangs of lead A.B.C.D.E.F.G, and wherein: lead A.B.C is connected with three of stator 2 respectively; Lead D is connected with the motorcycle ignition coil; Lead E, F are connected with trigger 3; Lead G is the neutral line.Lining 5 is used injection molding, and being contained in rotor is in the flywheel 1, and as the magnet steel axial location, guard shield 6 usefulness stainless steels are made. the protection magnet steel, and avoid magnet steel to come off.
Employing the utility model three-phase alternating current magneto as shown in Figure 3 is installed in the line map on the motorcycle: trigger 3, three-phase alternating current magneto 7, variable voltage rectifier 8, storage battery 9, lighting headlight 10, igniter 11 on the motorcycle.
Motorcycle engine is the keyway driven rotary of flywheel 1 cam taper hole by the rotor of three-phase alternating current magneto 7, produces alternating magnetic field, and the rotor that power is sent to the three-phase magneto is that flywheel 1 drive rotor is flywheel 1 rotation.The stator 2 of three-phase alternating current magneto 7 is the magnetic force line cutting of the alternating magnetic field that produces of flywheel 1 and produce three-phase alternating-current supply by rotor.The electric energy that stator 2 and trigger 3 are produced is transported to respectively on the variable voltage rectifier 8 and ignition 11 on the motorcycle by wire harness 4, and variable voltage rectifier 8 and storage battery 9 supply power to lighting headlight 10 in parallel.Trigger 3 produces trigger impulse for igniter 11 normal electronic ignitions, thereby reaches the purpose that electricity is piloted engine by the rocket ignition time requirement.
The advantage of the utility model three-phase alternating current magneto:
1. the three-phase alternating current magneto rotor is that flywheel 1 is eight grades of magnet steel; with lining 5 and 6 protections of stainless guard shield; stator 2 adopts 11 polar curve circle windings; after this three-phase alternating current magneto is installed on the engine of motorcycle; the three-phase alternating current that produces can make engine power generation (output) power be brought up to more than the 120W by the 60W of single-phase magneto through full-wave rectification; power supply wave shape is more level and smooth behind the voltage regulating rectifier; the charging quality is improved; charging current improves 3-4 doubly than single-phase magneto; the electric energy that can in time satisfy after motorcycle battery 9 frequently discharges replenishes, and has improved the electric starting performance of motorcycle.Prolong 9 useful lifes of storage battery simultaneously, can reach more than 2 years.
2. the brightness of lighting headlight 10 is not subjected to the influence of motorcycle engine rotating speed, has ensured the fail safe of motorcycle at the low speed driving at night.Because voltage constant has prolonged the useful life of lighting headlight 10 bulbs.
