AC generator for vehicle

Abstract

The invention discloses an alternating-current generator used for vehicles. Grooves are formed on the stator core in a ratio of 2 per pole per phase. The stator winding is formed by a first three-phase stator winding and a second three-phase stator winding, which are wound around the stator core at an electrical angle of 30 DEG to 34 DEG. Each conducting wire forming the stator winding is provided with a slot accommodating part which is placed in a slot and shaped with a flat cross section. The slot accommodating parts are arranged in a row in the radial direction and placed inside the slot in a laminated manner. The coil ends of the stator winding and the slots are impregnated with the varnish paint.

Description

technical field [0001] The present invention relates to a vehicle alternator that generates an AC voltage in a stator by utilizing rotation of a rotor. Background technique [0002] Figure 16 is a longitudinal sectional view of a conventional vehicle alternator (hereinafter, simply referred to as an alternator), Figure 17 Shown is a perspective view of a rotor of a conventional generator, Figure 18 Shown is a perspective view of a stator of a conventional generator, Figure 19 For the circuit diagram of the conventional generator, Figure 20 Shown is a perspective view of a stator core of a conventional generator, Figure 21 It is an explanatory diagram for explaining the winding structure of the stator winding part of the one-phase part in the stator of the conventional generator. In addition, in Figure 18 In , the lead-out wire and neutral wire of the stator winding are omitted. [0003] exist Figure 16 to Figure 18 Among them, the generator has: a casing 3 com...

Problems solved by technology

[0021] However, since the lead wire 30 is not fixed to the groove 15c, there is a problem that the lead wire 30 rubs against each other due to the vibration of the lead wire 30, or the lead wire 30 rubs against the wall surface of the groove 15c, and the insulating protective film is damaged and the insulation performance deteriorates.

[0022] In addition, since the extension parts 30a are not fixed to each other, there is also a problem that the insulating protective film is damaged due to the friction between the extension parts 30a, and the insulation performance is deteriorated.
