Description

Technical Field

[0001] This invention relates to a magnetic pole excitation coil for a generator rotor, and more particularly to a method for winding a copper flat wire rotor magnetic pole excitation coil with inter-pole or inter-pole leads. Background Technology

[0002] Some three-phase brushless synchronous generators use a salient-pole magnetic pole structure for their rotors. In the assembly process of the rotor magnetic poles for this type of generator, the concentric coils of each phase group within the same pole are first wound separately. Then, each concentric coil is embedded into the corresponding iron core slot of the same phase group. Next, the concentric coils are connected in series to form the N-pole or S-pole excitation coil of the generator rotor. Finally, the N-pole and S-pole excitation coils are connected in series to the excitation power supply, thus forming the excitation circuit for the generator rotor magnetic poles. Powered by the excitation power supply, the N-pole or S-pole magnetic poles of the generator are formed. Since the excitation coils of the same phase group are composed of multiple multi-turn coils of different sizes connected in series in different slots, each coil is wound individually on a coil mold. The existing coil winding mold structure can only complete… The coil forming process cannot involve forming the coil and leads in one go. Separate fixtures are needed for inter-coil and inter-pole leads. These leads are fabricated on these fixtures, and then welded to adjacent coils that are individually embedded in their corresponding core slots to achieve series connection of the excitation coils. This coil winding and connection method increases the number of connection solder points for the excitation coils, leading to increased risks in winding welding and higher fixture costs. A key challenge is how to pre-define the inter-coil or inter-pole leads during coil winding to achieve integrated winding with the coil. After subsequent winding, adjacent coils can be directly butt-welded, improving pole assembly efficiency and reducing coil connection solder points. This is a problem that needs to be solved on-site. Summary of the Invention

[0003] This invention provides a method for winding a copper flat wire rotor magnetic pole coil with inter-pole or inter-pole leads, which realizes the integrated winding and forming of the inter-pole or inter-pole leads and the coil, greatly improving the reliability of the excitation coil.

[0010] Step 1: Take the copper flat wire that is wound into the inner coil of the same pole phase group, bend the end of the copper flat wire into an L shape, and fix it under the inter-lead end pressure plate fixing mechanism set on the H-shaped base plate;

[0011] The second step is to use the end of the L-shaped copper flat wire as the starting point for winding the inner coil of the same pole phase group. First, embed the copper flat wire into the insertion groove of the intercalation lead forming. Then, in a clockwise direction, wind the copper flat wire coil between the left lamination group and the right lamination group until the inner coil of the same pole phase group is completed, and obtain the inner coil of the same pole phase group with the intercalation lead of the flat copper wire.

[0012] The outer coil of the same pole phase group is wound using a copper flat wire rotor magnetic pole coil winding tool that pre-forms the interlocking leads.

[0014] Step 1: Take the copper flat wire used to wind the N-pole coil, bend the end of the copper flat wire into an L-shape, and press it onto the H-shaped base plate.

[0015] The second step is to use the end of the L-shaped copper flat wire as the starting point for winding the N-pole coil. Wind the copper flat wire coil counterclockwise between the left and right lamination groups until the N-pole coil is completed. Then, wind the copper flat wire at the end of the coil clockwise into the groove of the inter-pole lead set on the bottom surface of the rear cantilever plate to obtain the N-pole coil with the inter-pole lead.

[0016] The S-pole coil is wound using a copper flat wire rotor magnetic pole coil winding fixture with pre-formed inter-pole leads. The ends of the S-pole coil are then directly welded to the N-pole coil through inter-pole leads to form a series excitation coil.

[0025] The present invention will now be described in detail with reference to the accompanying drawings:

[0026] A winding fixture for a copper flat wire rotor magnetic pole coil with pre-formed inter-pole or inter-pole leads includes an H-shaped base plate 1, an inner coil 14 of the same pole phase group, and an outer coil 15 of the same pole phase group. A center positioning strip 2 is provided in the middle of the H-shaped base plate 1. The length of the center positioning strip 2 determines the size of the wound coil. The left end of the center positioning strip 2 is connected to the left lamination group 3 by a mortise and tenon joint, and the right end of the center positioning strip 2 is connected to the right lamination group 6 by a mortise and tenon joint. The H-shaped base plate 1 is located on the left side of the H-shaped base plate 1. The base plate 1 is provided with a left stacked plate group 3, which is composed of multiple steel plates stacked together.

A right stacked plate group 6 is provided on the right side of the H-shaped base plate 1. A right top pressure plate 7 is provided at the top of the right stacked plate group 6. The H-shaped base plate 1, the right stacked plate group 6, and the right top pressure plate 8 are connected together by right stacked plate clamping bolts 8. On the right stacked plate group 6, U-shaped flat copper wire winding right embedding grooves 21 are arranged parallel to each other at intervals along the vertical direction. The wound copper flat wire is embedded into the corresponding flat copper wire winding left embedding groove 9 and flat copper wire winding right embedding groove 21 in a clockwise or counterclockwise circular manner. The coil is formed by passing through the gap between the left lamination group 3 and the right lamination group 6. The lowermost lamination 10 of the left lamination group 3 is an outwardly extending lamination. A reinforcing groove 11 for forming inter-leads is provided between the lowermost lamination 10 and the H-shaped base plate 1. The outward extension dimension of the lowermost lamination 10 is determined according to the length of the inter-lead of two adjacent same-pole phase coils. When the coil is wound with this winding tool, the coil body will protrude at the starting end of the coil, naturally forming inter-leads.

[0027] An inter-lead forming embedding groove 11 is provided on the H-shaped base plate 1 outside the inter-lead forming embedding groove 11. An inter-lead flat copper wire inter-lead 13 of the inner coil 14 of the same pole phase group is provided in the inter-lead forming embedding groove 11. The inter-lead end pressure plate fixing mechanism 12 is composed of a pressure plate and a set screw. The pressure plate is fixed to the outer vertical surface of the H-shaped base plate 1 by connecting bolts. The set screw is abutted on the L-shaped head of the copper flat wire end bent into a top, which becomes the head of the copper flat wire winding.

[0028] A copper flat wire rotor magnetic pole coil winding fixture with pre-formed inter-pole or inter-pole leads includes an H-shaped base plate 1, an N-pole coil 19, and an S-pole coil 20.

On the left lamination group 3, flat copper wire winding left embedding grooves 9 are arranged parallel to each other along the vertical direction. A right lamination group 6 is provided on the right side of the H-shaped base plate 1, and a right top pressure plate 7 is provided at the top of the right lamination group 6. The H-shaped base plate 1, the right lamination group 6, and the right top pressure plate 8 are connected together by the right lamination clamping bolt 8. On the right lamination group 6, flat copper wire winding right embedding grooves 21 are arranged parallel to each other in the vertical direction. A rearward cantilever plate 16 is connected at the left rear corner of the left top pressure plate 4. An inter-pole lead embedding groove 17 is provided on the bottom end surface of the rearward cantilever plate 16. After the N pole coil 19 is wound counterclockwise to the tail end by this tooling, it is wound clockwise into the inter-pole lead embedding groove 17 provided on the bottom end surface of the rearward cantilever plate 16 to form an inter-pole lead 18. This allows the inter-pole lead 18 at the tail end of the N pole coil 19 to be directly welded to the head end of the N pole coil 19 after the N pole coil 19 and the S pole coil 20 are embedded into the iron core slot of the motor rotor, thus realizing the series connection of the two pole coils.

[0029] An inter-pole lead end pressure plate fixing mechanism 12 is provided on the H-shaped base plate 1, and an inter-pole lead 18 of the N-pole coil 19 is provided on the inter-pole lead embedding groove 17; the inter-pole lead end pressure plate fixing mechanism 12 fixes the starting end of the copper flat wire for winding the coil, and then the coil is wound; after the N-pole coil 19 is wound, the S-pole coil 20 can be wound through this tooling.

[0030] A method for winding a copper flat wire rotor pole coil with intercalation leads is achieved using a winding fixture for copper flat wire rotor pole coils with pre-formed intercalation leads. The winding fixture includes an H-shaped base plate 1, an inner coil 14 of the same pole phase group, and an outer coil 15 of the same pole phase group. A center positioning strip 2 is provided in the middle of the H-shaped base plate 1. A left lamination group 3 is provided on the left side of the H-shaped base plate 1. A left top pressure plate 4 is provided at the top of the left lamination group 3.

The H-shaped base plate 1, the right stacked plate group 6 and the right top pressure plate 8 are connected together by right stacked plate clamping bolts 8.

[0031] Step 1: Take the copper flat wire that is wound into the inner coil 14 of the same pole phase group, bend the end of the copper flat wire into an L shape, and fix it under the inter-lead end pressure plate fixing mechanism 12 set on the H-shaped base plate 1.

[0032] The second step involves using the end of an L-shaped copper flat wire as the starting point for winding the inner coil 14 of the same pole phase group. First, the copper flat wire is inserted into the intercalation lead forming insertion groove 11. Then, the copper flat wire coil is wound clockwise between the left lamination group 3 and the right lamination group 6 until the inner coil 14 of the same pole phase group is completed, resulting in the inner coil 14 of the same pole phase group with the flat copper wire intercalation lead 13. Since the intercalation lead forming insertion groove 11 extends outside the insertion grooves of other coils, the end of the wound coil forms the flat copper wire intercalation lead 13. The outer coil 15 of the same pole phase group can also be wound using this tooling, except that the starting head is set in the insertion groove of other coils above the intercalation lead forming insertion groove 11 during winding.

[0033] The outer coil 15 of the same pole phase group is wound using a copper flat wire rotor magnetic pole coil winding tool that is pre-formed with interlocking leads. The inner coil 14 and the outer coil 15 of the same pole phase group, which are wound using the same tool, are respectively embedded into the coil embedding slots on the corresponding electrode rotor core of the same pole phase group. The ends of the outer coil 15 of the same pole phase group are directly welded to the inner coil 14 of the same pole phase group through the flat copper wire interlocking leads 13 to form the excitation coil of the same pole phase group.

On the right stacked plate group 6, flat copper wires are wound into right embedding slots 21 at intervals and parallel to each other in the vertical direction; a rearward cantilever plate 16 is connected at the left rear corner of the left top pressure plate 4, and an inter-electrode lead wire embedding groove 17 is provided on the bottom end surface of the rearward cantilever plate 16; the winding method includes the following steps:

[0035] Step 1: Take the copper flat wire used to wind the N-pole coil 19, bend the end of the copper flat wire into an L-shape, and fix it on the H-shaped base plate 1.

[0036] The second step is to use the end of the L-shaped copper flat wire as the starting point for winding the N-pole coil 19. Wind the copper flat wire coil between the left lamination group 3 and the right lamination group 6 in a counterclockwise direction until the N-pole coil 19 is completed. Then, wind the copper flat wire at the end of the coil clockwise into the groove 17 where the inter-pole lead is set on the bottom surface of the rear cantilever plate 16, thus obtaining the N-pole coil 19 with the inter-pole lead 18.

[0037] The S-pole coil 20 is wound using a copper flat wire rotor magnetic pole coil winding fixture with pre-formed inter-pole leads. The N-pole coil 19 and the S-pole coil 20 are then embedded into the corresponding S-pole coil embedding slots and N-pole coil embedding slots on the motor rotor, respectively. The ends of the S-pole coil 20 and the N-pole coil 19 are then directly welded together through the inter-pole leads 18 to form a series excitation coil.
