DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a dual-winding power generation and welding machine, such as Figure 1-Figure 5 As shown, a dual-winding generator and welder comprises a generator and welder body 1 and a connection port 4; a connection port 4 is provided at the front end of the generator and welder body 1, a dustproof structure 5 is provided on one side of the connection port 4, and a door 3 is provided at the front end of the generator and welder body 1 at the bottom end of the connection port 4; a heat dissipation structure 2 is provided on one side of the generator and welder body 1, a handle 6 is provided at the top end of one side of the generator and welder body 1, a stator 7 is provided inside the generator and welder body 1, and a rotor 8 is provided inside the stator 7; a dual winding structure 9 is provided on the inner side of the stator 7.

[0022] In a further preferred embodiment of the present invention, Figure 1-Figure 5 As shown: the dual winding structure 9 includes a first permanent magnet 901, a first armature winding 902, a second permanent magnet 903 and a second armature winding 904, the first permanent magnet 901 is arranged on one side inside the stator 7, the second permanent magnet 903 is arranged on the other side inside the stator 7, the first armature winding 902 is arranged on one side of the inner wall of the stator 7, and the second armature winding 904 is arranged on the other side of the inner wall of the stator 7.

[0023] Specifically, in this embodiment: in a two-phase generator, if the windings are designed to have a phase angle of 90 degrees, then the spatial positions of the two windings in the magnetic field of the generator will be separated by an electrical angle of 90 degrees. This means that if one winding is located at the 0-degree position of the magnetic field, the other winding will be located at the 90-degree position. The two windings are usually designed to be in the same or different slots of the generator, but their layout must ensure that when the generator rotates, they can induce voltage waveforms that differ by 90 degrees. This is usually achieved by alternately placing the coils of the two windings in the slots of the generator stator. The windings of the two-phase generator can be connected in different ways, such as star (Y) connection or triangle (Δ) connection. In the star connection, the tail ends of the two windings are connected and the head ends are led out separately; in the triangle connection, the head and tail of the two windings are connected to form a closed loop. The two windings with a 90-degree phase angle can be controlled independently, which provides higher flexibility for motor control. In some applications, the 90-degree winding can produce a uniform torque distribution, which helps to reduce vibration and noise during motor operation. The two windings of the two-phase generator can output different powers respectively, which is very useful in applications that require precise control of power output. There are two windings on the upper and lower cores, and the coils of the two windings are in different wire slots, which do not affect each other. Through rectification, the welding voltage is converted from AC to DC output, achieving the effect of charging while using.

[0024] In a further preferred embodiment of the present invention, Figure 1-Figure 5 As shown: the heat dissipation structure 2 includes a heat dissipation port 201, an air inlet 202, a fan 203 and a protective frame 204.

The dustproof structure 5 includes a dust cover 501, a fixing frame 502, a torsion spring 503 and a fixing column 504. The fixing frame 502 It is arranged on one side of the connecting port 4, a fixing column 504 is arranged inside the fixing frame 502, a dust cover 501 is arranged on the outside of the fixing column 504, a torsion spring 503 is arranged at both ends of the outside of the fixing column 504, one end of the torsion spring 503 is connected to one side of the dust cover 501, and the other end of the torsion spring 503 is connected to one end of the fixing frame 502, one end of the dust cover 501 is sleeved on the outside of the fixing column 504, and a movable connection is formed between the dust cover 501 and the fixing column 504, and two groups of torsion springs 503 are arranged, and the two groups of torsion springs 503 are symmetrically distributed at both ends of the outside of the fixing column 504.
