Alternating-current generator and stator thereof

Abstract

The invention provides an alternating-current generator and a stator thereof. The alternating-current generator stator provided by the invention comprises a stator iron core and also comprises multiple annular circuit boards, multiple line-clamping chips, multiple magnetic induction line cutting components, wherein the multiple annular circuit boards are symmetrically distributed at the two sides of the stator iron core; the multiple line-clamping chips are located on the annular circuit boards and electrically connected with the annular circuit boards; the two ends of each magnetic induction line cutting component are positioned in each line-clamping chip and electrically connected with each line-clamping chip; and the magnetic induction line cutting components are arranged on the inner surface of the alternating-current generator stator through the line-clamping chips, and the magnetic induction line cutting components which are in the same phase are successively connected through the annular circuit boards. According to the alternating-current generator stator provided by the invention, multiple segments of magnetic induction line cutting components and the annular circuit boards are used as three-phase windings to cut magnetic induction lines without bending parts among the magnetic induction line cutting components so that the tank-full rate of the inserting coil of the stator is improved.

Description

technical field [0001] The invention relates to the field of a vehicle alternator, and more specifically relates to an alternator and a stator thereof. Background technique [0002] The stator winding of the traditional alternator is wound by a complete copper wire, which has been bent many times, and the winding cannot be assembled in the case of a high slot fullness of the stator. In addition, the copper wire outside the stator core of the generator is less involved in the cutting of the magnetic induction line, and the utilization efficiency of the copper wire is very low, which causes waste of copper wire and increases the cost. In addition, as attached Figure 5 As shown, the wiring method of the traditional stator winding is equivalent to connecting in series and then in parallel, that is, the resistance of each phase is equivalent to multiple resistors R' in series, the total resistance of the system is equivalent to the total resistance of each phase in parallel, and...
