Problems solved by technology

Therefore, even in this case, the magnetic flux of the permanent magnet is not effectively used, and the power generation output and power generation efficiency may decrease.
[0011] In addition, in the technology described in the above-mentioned Patent Document 2, it is only shown that by including a thyristor in the rectifier to control the output of the stator coil, the electric loss of the generator is reduced, and the output loss of the entire rotation range of the engine is reduced. technology, there is no record of revelation

no. 1 Embodiment approach

[0064] figure 1 It is a left side view of the engine unit of a motorcycle to which the first embodiment of the generator for motorcycle of the present invention is applied. figure 1 Among them, the power unit 10 has an air-cooled four-stroke single-cylinder engine 11, the engine 11 is mainly composed of: a crankcase 12 rotatably supporting and accommodating a crankshaft 19; and a cylinder block 13 coupled to the end of the crankcase 12; A cylinder head 14 coupled to the cylinder block 13; and a head cover 15 coupled to the cylinder head 14. In addition, the generator for a motorcycle of the present invention is installed in the power unit of the motorcycle.

[0065] In this embodiment, the crankcase 12 is configured to be divided into two left and right. in figure 2 In the crankcase 12, the right crankcase 12R and the left crankcase 12L that are paired on the left and right are coupled to each other to be integrated to form the crank chamber 18. In the crank chamber 18, a cra...

no. 2 Embodiment approach

[0088] Next, refer to Figure 12 to Figure 2 0 The second embodiment of the motorcycle generator of the present invention will be described.

[0089] The motorcycle generator of the second embodiment is installed in the power unit of the motorcycle of the first embodiment, and is similar to the motorcycle generator of the first embodiment. Figure 1 to Figure 3 The structure of the magnetic device 31 is the same, so the same structure is labeled with the same symbol, and repeated description is omitted or simplified.

[0090] The motorcycle generator of the second embodiment has a single-phase or three-phase magnetic alternator 31A as a magnetic device. Such as Picture 12 As shown, the magneto-generator 31A is configured to include: a stator 33 coaxially with the crankshaft 19 and arranged around the crankshaft 19; and a rotor 34 that rotates integrally with the rotation axis of the crankshaft 19 around the stator 33. The rotor 34 is fixed to the left end of the crankshaft 19, an...

Abstract

A generator for a two-wheeled motor vehicle is disposed within the power unit of the vehicle and has: a stator configured by winding stator coils around stator teeth, respectively, the stator teeth extending radially from the center; and a rotor configured by arranging magnets on the inner peripheral surface of a rotor yoke and rotating about the center, i.e., around the stator. The generator for a two-wheeled motor vehicle is configured in such a manner that: the magnets are arranged in the circumferential direction of the rotor so as to be adjacent to each other with gaps therebetween; the stator teeth are formed by stacking core sheets on each other, the core sheets being thin sheets of steel; the stator teeth each have tip sections extending in the rotational direction of the rotor and in the direction opposite the rotational direction, from the coil-wound section of the stator tooth, the coil-wound section being that around which the stator coil is wound; and when the leading end of a magnet in the rotational direction substantially coincides with the centerline of the coil-wound section, one of the tip sections of each of the stator teeth, said tip section extending in the rotational direction of the rotor, overlaps the preceding magnet adjacent to the leading end of the magnet in the rotational direction.

Description

Technical field [0001] The present invention relates to a generator for motorcycles that reduces electric loss and improves power generation output and power generation efficiency. Background technique [0002] As a generator for motorcycles, there is known Figure 22 The structure shown uses a magneto generator 100. The magneto generator 100 has a stator 103 in which stator (power generation) coils 102 are wound around a plurality of stator teeth 101 and a rotor 106 in which magnets 105 are provided on the inner peripheral surface of a rotor yoke 104. The electromagnetic induction effect generated by the rotation of the rotor 106 around the stator 103 due to the driving force of the engine causes an induced current in the power generating coil 102 to generate power. [0003] In the magneto generator 100, four magnets 105 are provided on the inner peripheral surface of the rotor yoke 104, for example. Such as Figure 23 As shown, in each magnet 105, three magnetic poles constituti...
