Problems solved by technology

However, there is a problem that, when the armature is configured in this way, although the reduction of the magnetostrictive sound is aimed at, on the other hand, the number of salient pole portions around which the charging coil is wound is less than the conventional one. The number of salient poles wound with load coils increases, resulting in an increase in the number of steps

Abstract

The invention relates to an armature structure of generator, which can reduce the magnetic flexible sound. It comprises: an iron core (71) with a main body (71a) inside the inner space of rotor (60) and several project poles (I-VIII) projected from the main body (71a) and distantly arranged along the inner circumference of rotor (60); a load coil (72a) that coiling some projected poles (I, II, IV, V, VII) to supply electricity to the electric load (L); and a charge coil (72b) that coiling the left projected poles (III, VI, VIII) to send electricity of the accumulator (B)l; the projected polesthat coiled with charge coil (72b) are between the projected poles coiled with load coil (72a).

Description

technical field [0001] The present invention relates to an armature structure of a generator in which an armature is arranged in a cylindrical inner space of a rotor. Background technique [0002] Among the generators installed on vehicles, there is a magnet generator with a structure including a rotor formed by fixing permanent magnets on the inner peripheral surface of a cylindrical yoke, and a rotor that is installed inside the yoke and on the salient pole portion of the iron core. The armature (electron) composed of wound coils rotates the rotor to obtain electromotive force. A generator installed in a motorcycle is configured to rotate and drive a rotor with power from an engine, generate induced electromotive force in each coil, and supply electric power to a power load device such as a headlight or a battery (for example, Patent Document 1). [0003] In addition, as shown in FIG. 5 , a conventional armature 80 has a structure in which a plurality of (eight in FIG. 5 ...
