Generator stator structure

Abstract

The invention relates to a generator stator structure which can improve current output; stator line connecting ends are connected to form the stator coil with a tower-shaped symmetrical structure, the two ends of each stator coil winding are respectively connected with outgoing lines for leading out, a plurality of the stator core windings are installed inside an iron core slot and positioned by a positioning wedge. The structure has the advantages that: a plurality of air gaps are left at the two ends of the stator iron core and the end part of the stator winding, thus increasing the area of the wind path. Wind generated by the rotation of a fan can pass through the air gaps, and due to the existence of the air gaps, more wind can pass the surface of the end part of the stator winding and bring away more heat, thus reinforcing the heat dissipation property of the end part of the stator winding. The temperature of the stator winding can be reduced by about 10 DEG C under the condition of the same output power, and the output current can be improved by 5 amperes under the condition of the same stator winding temperature.

Description

technical field [0001] This patent relates to a generator stator structure, which is suitable for various alternators. technical background [0002] When the generator is working, the shaft rotates and drives the fan to rotate. The wind generated by the rotation of the fan enters from the front of the generator, and blows to the end 5a of the stator winding 5 through the fan 3 . [0003] The shape of the existing generator stator coil is as follows Figure 9 , Figure 10 , Figure 11 As shown, after the three-term coil is embedded on the iron core, the wires at the end of the stator winding are arranged relatively tightly and messily. When the generator is working, the stator winding generates a large amount of current. , the wind path generated by the rotation of the fan on the rotor will bypass the end of the stator winding and cool the end of the stator winding, which cannot effectively dissipate heat from the coil of the stator winding.
