れる。FIG. 2 shows a positional relationship between the tooth portion 13 of the stator core 12 and the claw-shaped magnetic poles 15a and 16a of the rotor in electrical angle. In the U phase, the claw magnetic pole 1 of B is located at the center of the tooth portion 13b.
When the center of 5a is reached, the center of the tooth portion 13a is delayed by 20 electrical degrees from the center of the claw magnetic pole 16a of A, and the center of the tooth portion 13c is advanced by 20 electrical angle to the center of the claw magnetic pole 16a of C. I'm out. Further, in the V phase, the center of the tooth portion 13d leads the center of the D claw pole 15a by an electrical angle of 40 °. Therefore, the V-phase first coil 14b 1 is the U-phase first coil 1
4a 1 is deviated from the electrical angle by 120 °. Similarly, the W-phase first coil 14c 1 is 120 ° apart from the V-phase first coil 14b 1 .
Deviated. As a result, the three-phase AC generator maintains the three-phase balance and stable DC power is supplied through the rectifier.

On the other hand, the tooth portions 13 facing each other are dispersed and arranged so that the electrical angles are not the same. This will be described with reference to the explanatory diagram of the electrical angle between the claw magnetic poles 15a and 16a and the tooth portion 13 shown in FIG. The claw pole 15a is attached to the tip of the U-phase first tooth 13a.
In the state where the tip reaches, the second tooth portion 13b has an electrical angle of 20
.Degree., And the third tooth portion 13c is advanced by 40.degree. In electrical angle.
Further, the V-phase first tooth portion 13d is advanced by an electrical angle of 60 °, and is displaced from the U-phase first tooth portion 13a by an electrical angle of 120 °. To establish such a three-phase winding, 360 × m × 1/3 = 360 × n + 120 (1) 360 × m = 360 × 3n + 360 ° ∴m = 3n + 1 ………………………… (2) where m: logarithm of poles n: integer (1, 2, 3 ...), electrical angle for 360: 1 phase 120: electrical of 1-phase first coil of 2-phase first coil Angle deviation 1/3: 1/3 phase

総和は、数１で示すようになる。When the ratio of the number of magnetic poles to the number of teeth is 8: 9, for example, the induced electromotive force shown in FIG. 4A is generated in the group of three stator coils 14 of U phase. When these are connected so as to be added, the electromotive force vector synthesis shown in FIG. The total sum of the combined induced electromotive force vectors is as shown in Equation 1.

This is 0.96, which is a slight decrease rate. However, since the number of teeth is not divisible by the number of poles in the embodiment, torque ripple is significantly reduced. In particular, in order to obtain both the effect of improving the output and reducing the electromagnetic noise, a combination in which the ratio of the number of magnetic poles and the number of teeth is indivisible such as 8: 9, 8:15, 8:21 is preferable. ..

個所が少ないためである。When the rotor is rotated to excite the magnetic pole cores 15 and 16 to generate electric power, as shown in FIG. 5, fluctuations in the rotational torque between the stator and the rotor become extremely small. This is because there are few places where the electrical angles of the claw-shaped magnetic poles 15a and 16a and the tooth portions 3 match.

低下するので限定される。From the equation (2), the number of magnetic poles is 2m = 2 (3
n + 1). On the other hand, it is necessary that the number of teeth of 3K is not divisible by the number of magnetic poles. 3 is a multiple for making three phases, and K is the following condition. 2 (3n + 1)>K> 2
n where n: integer (1, 2, 3, ...) If the number of teeth is too large relative to the number of magnetic poles, the synthesis of the induced starting force becomes undesired, and the size of the stator core 12 for vehicles is also large. It is not preferable due to limitations. Further, when the number of magnetic poles is too large, the number of clearances in the circumferential direction between the adjacent claw-shaped magnetic poles 15a and 16a increases, the magnetic path cross-sectional area decreases, and the output decreases, which is a limitation.

り、電磁騒音が低減される。As described above, according to the present invention, the ratio of the number of poles of the claw-shaped magnetic pole is 2 (3n + 1), the ratio of the number of teeth of the stator core to this is 3K, and the range of K is 2
(3n + 1)>K> 2n (n is an integer), the stator coil is concentratedly wound around each tooth, and each stator coil is continuously K
Since the stator coils of each group are continuously connected so that the electromotive force is added and these groups are connected to the three-phase windings, fluctuations in rotational torque between the stator and rotor are small. And electromagnetic noise is reduced.
