Abstract
The utility model discloses a brushless generator of a motorcycle. An excitation coil assembly of the brushless generator of motorcycle is separated from a rotor assembly and is fixed on one end cap by a bolt, and a main axle of the rotor assembly is coaxially positioned by internal taper. The brushless generator of motorcycle has the advantages of compact structure, large output power, few wearing part, good generating performance, reliable quality and convenient maintenance, and can be adapted to various severe environmental conditions.
Description
The utility model relates to the brushless AC generator that a kind of motorcycle is used, on its motorcycle applicable to 250～750 series.
Now, most motor generator adopts brush configuration, and the volume of this motor is bigger, and its collector ring, carbon brush are consumable accessorys, and ubiquity external stator coil heating is serious, and excitation coil also damages easily, maintenance difficult.There are many technical schemes to propose improved imagination for this reason, for example Chinese patent CN252338Y about the stator main line that relates to a kind of generator in " no storage battery 250 series motorcycle generators ", by-pass all with the enamelled wire inhour around forming, stator major-minor line is bifilar inhour and around 50～60 circles, and between stator main line and ground, add an electric capacity, this generator can make the motorcycle cruising when no storage battery, but its character instability, consumable accessory is many, and power output is subjected to certain restriction.
Task of the present utility model is that a kind of motorcycle brushless generator will be provided, and this generator can save collector ring, carbon brush and brush holder parts, the compact conformation of complete machine, and power generation performance is good, few easy workout part, long service life, easy to maintenance.
Task of the present utility model is finished in such a way, this motorcycle brushless generator is made up of rotor assembly, external stator coil assembly and excitation coil assembly, the excitation coil assembly is by on the end cap that is bolted to motor, therefore it separates with rotor assembly, two utmost point pawls are embedded on the main shaft of rotor, and rotor is by the internal taper coaxial positioning.This generator Structure compactness, volume is little, and power output is big, and power generation performance is good during the high low cruise of motorcycle, and the product quality reliability height can adapt to various severe environmental conditions, and it is also quite convenient to keep in repair.
Below in conjunction with accompanying drawing the utility model is further elaborated.
Fig. 1 is a motorcycle brushless generator cutaway view of the present utility model.
As we know from the figure, the main parts of this generator are rotor assembly (1), external stator coil assembly (2) and excitation coil assembly (3).Excitation coil assembly (3) separates with rotor assembly (1), and it is fixed on the end cap (5) by bolt (4), and excitation coil assembly (3) can not followed rotor assembly (1) rotation like this, so it is not easy to damage.The main shaft (6) of rotor assembly (1) is by internal taper (7) coaxial positioning, and main shaft (6) can not swept the thorax phenomenon owing to centrifugal action produces like this.Go up two utmost point pawls (8) and (9) in addition at rotor assembly (1), these two utmost point pawls (8) are connected with brazing or stainless steel weldering with (9), in the periphery of utmost point pawl (8) and (9) is external stator coil (2), and this external stator coil (2) is the edge that is embedded in end cap (5).The performance of this motorcycle brushless generator is good, few easy workout part, and long service life, easy to maintenance.
Claims (1)
