Description

Technical Field

[0001] The utility model relates to a magnetic pole excitation coil of a generator rotor, in particular to a tool for winding a copper flat wire rotor magnetic pole coil with preformed inter-pole or inter-polar lead wires. Background Art

[0002] The rotors of some three-phase brushless synchronous generators adopt a hidden pole structure. In the assembly process of the rotor poles of this motor, the winding of each concentric coil of the same pole phase group must be completed separately, and then each concentric coil must be embedded in the corresponding core slot of the same pole phase group. Then, the concentric coils are connected in series in sequence to form the N-pole excitation coil or S-pole excitation coil of the motor rotor. Finally, the N-pole excitation coil and the S-pole excitation coil are connected in series and then connected to the excitation power supply, thereby forming the excitation circuit of the motor rotor pole. The N-pole magnetic pole or S-pole magnetic pole of the motor is formed by the power supply of the excitation power supply. Since the excitation coil of the same pole phase group is composed of a plurality of multi-turn coils of different sizes distributed in different wire embedding slots in series, each coil is wound separately on the coil mold, and the structure of the existing coil winding mold can only complete When forming the coil, the coil and the lead wire cannot be formed at one time. It is necessary to set up separate tooling for the heavy lead wire and the interpole lead wire, and make the heavy lead wire and the interpole lead wire on these two toolings respectively. Then the heavy lead wire or the interpole lead wire is welded and connected to the two adjacent coils embedded in the corresponding iron core slots separately to realize the series connection of the excitation coil. This coil winding and connection method increases the connection welding points of the excitation coil, which increases the risk of winding welding and increases the tooling cost. How to reserve the heavy lead wire or the interpole lead wire at one time during the coil winding process to realize the integrated winding and forming of the heavy lead wire or the interpole lead wire and the coil? After the subsequent wire embedding is completed, it is only necessary to directly butt-weld the two adjacent groups of coils, which improves the pole assembly efficiency and reduces the welding points of the coil connection. This has become a problem that needs to be solved on site. Summary of the Invention
