[0002] At present, in the prior art, the armature winding of the output voltage of the generator generally adopts a structure in which multiple coils are connected in series to form the armature winding of each phase. All coils must have the same structure, and the output voltage of the armature winding is determined by the total number of turns of the winding coil, so when the number of turns of the coil changes, the output voltage of the winding will change according to the number of coils multiple change, so the output voltage of this generator in the prior art is not easy to adjust
As shown in accompanying drawing 1, accompanying drawing 1 is the connection structure of one-phase armature winding in the prior art generator armature winding, and in accompanying drawing 1, one-phase armature winding of this generator is made up of 8 coils connected in series , when the number of turns of the coil changes, the output voltage change of the phase winding will change by 8 times the change of the number of turns of the coil, and the change is very large, so the output voltage is not easy to adjust
In addition, since each phase winding in the armature winding of the generator in the prior art is composed of a plurality of coils connected in series, due to the limitation of its structure, all welding spots of the winding must be welded together, so the welding spots are relatively large , so that the end of the winding is higher, thereby increasing the volume of the generator
Therefore, the existing generators still have the disadvantages of large size and uncompact structure.

Embodiment Construction
[0014] Embodiments of the present invention: the stator 1, the rotor 2 contained in the stator and the coil 4 forming the three-phase armature winding can all be made according to the method of the prior art. When making, the three-phase armature installed on the stator 1 Each phase of the armature winding 3 in the winding 3 is composed of 8 coils 4, and every two coils 4 are connected in series as a unit output coil, and then all the unit output coils in each phase of the armature winding 3 are connected in parallel connection; when all the unit output coils in the armature winding 3 of each phase are connected in parallel, they are connected in parallel with each other through the annular connection wire 5 arranged at one end of the armature winding, and the connection solder points are evenly distributed in the Serve on the circumference of ring connection line 5.

This invention discloses a generator including a stator and a rotor in it, in which, in the three-phase armature winding on the stator, each winding is composed of 4 coils and each two coils are serial to a unit output coil, all unit output coils in the armature winding are parallel, which can adjust its output voltages more accurately, besides, since the welding points of the winding are welded on a connection line uniformly in a circle, and the welding points are small, the end part of the winding is low and the volume of a generator is reduced.
Description
