Description

Technical Field

[0001] This utility model relates to the field of servo motor technology, and in particular to a servo motor with a combined iron core structure. Background Technology

[0002] Current servo motors use 12 sets of coil windings, each requiring a separate lead wire, totaling W, U, and V wires. During manufacturing, due to the alternating arrangement of the W, U, and V wires, it takes four turns to wind all 12 sets of coils before finally connecting the main bus of the W, U, and V wires to a separate circuit board. This traditional installation structure leads to cumbersome winding processes and reduces the servo motor's operating efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a servo motor with a combined iron core structure to solve the problems encountered in the background art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A servo motor with a combined iron core structure includes a frame and a stator iron core. The frame has 12 parts, which are respectively installed on the stator iron core. Each frame has a winding installed in it. Parallel conductive elements are installed alternately on the 12 frames. The stator iron core is a split combined structure.

[0006] In the above scheme, the top of the skeleton on which the parallel conductive component is installed has a slot, the bottom of the parallel conductive component has a plug rod inserted into the slot, and the top of the parallel conductive component has a terminal post.

[0007] As a preferred embodiment, a wire-passing hole is provided on one side of the top of the frame on which the parallel conductive component is installed. The terminal has a U-shaped structure, and the bottom of its slot is integrally connected to the plug rod. The material of the parallel conductive component is any one of copper, aluminum, stainless steel, and silver.

[0008] The frame includes an outer backing plate, an inner backing plate, and a winding frame. One side of the winding frame is connected to the outer backing plate, and the other side is connected to the inner backing plate. The winding is installed in the winding frame and is limited by the outer backing plate and the inner backing plate. A slot for connecting to the stator core is provided in the middle of the winding frame.

[0009] As a preferred embodiment, the inner wall of the slot is provided with limiting wings.

[0010] The stator core includes a core yoke and a core tooth. The outer circumferential surface of the core tooth is provided with a tooth profile that engages with a slot. The core tooth is glued to the core yoke through the tooth profile.

[0011] Compared with existing technologies, the advantages of this invention are as follows: By interlacing the parallel conductive elements on the frame, the windings on the stator core are adjusted from the conventional 12 individually wound segments to 4 continuously wound coils, thereby reducing the subsequent rewiring process. Furthermore, by designing parallel conductive elements and slots on the insulating frame on the stator core, the parallel conductive elements are used for partial parallel winding operations. Compared with traditional structures, this saves the circuit board used for logic paralleling, while achieving the same output torque performance. Attached Figure Description

These drawings are simplified schematic diagrams, illustrating only the basic structure of this utility model, and therefore only show the relevant components of this utility model.

[0020] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0021] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 and Figure 2 As shown, a servo motor with a combined iron core structure includes a frame 1 and a stator core. Twelve frames 1 are mounted on the stator core, and each frame 1 contains a winding 3, a common structure in conventional servo motors. Compared to traditional servo motors, this design features 12 frames 1 with staggered parallel conductors 2, which connect the wire ends of the windings 3 in parallel, thus avoiding individual windings.

[0023] Furthermore, to facilitate parallel winding and make it easier for workers to wind the components, the stator core is designed as a modular assembly structure. In the stator structure, the winding process of the frame 1 is changed from winding 12 individual single-tooth windings separately to winding 4 single-tooth windings connected together. This does not interrupt the parallel installation structure, reduces the subsequent parallel winding process, and eliminates the need to use a circuit board for additional parallel winding.

[0024] The top of the frame 1 on which the parallel conductive component 2 is installed has a slot 11, and the bottom of the parallel conductive component 2 has a plug rod 21 that is inserted into the slot 11. When inserted, it is interference-fitted. The top of the parallel conductive component 2 has a terminal post 22 for connecting two wires.

[0025] As a preferred embodiment, the top side of the frame 1 on which the parallel conductor 2 is mounted has a wire-passing hole 12 for threading the wire end through and securing it, facilitating the paralleling operation. The terminal 22 has a U-shaped structure, with its slot bottom integrally connected to the plug rod 21, for connecting the two wires of the winding 3. The material of the parallel conductor 2 can be any one of copper, aluminum, stainless steel, or silver; copper sheets or copper strips with good conductivity are preferred due to their high conductivity and low cost.

[0026] The stator structure paralleling process has been changed from the traditional method of connecting all 12 windings 3 to the circuit board using a circuit board, to setting through holes 12 and copper plate slots 11 on the insulated frame 1. By connecting a few wires on the copper plate, logic paralleling is achieved, reducing raw material costs.

[0027] The frame 1 is made of insulating material and includes an outer backing plate 13, an inner backing plate 14, and a winding frame 16. One side of the winding frame 16 is connected to the outer backing plate 13, and the other side is connected to the inner backing plate 14. The winding 3 is installed in the winding frame 16 and is limited by the outer backing plate 13 and the inner backing plate 14, which clamps the winding 3 between the two backing plates. A slot 15 for connecting to the stator core is opened in the middle of the winding frame 16.

[0028] As a preferred embodiment, the inner wall of the slot 15 is provided with a limiting wing 17, which clamps the tooth 51 when it passes through, thereby fixing the stator core and the frame 1 together.

[0029] In implementation, the stator core includes a core yoke 4 and a core toothed portion 5. The outer circumferential surface of the core toothed portion 5 is provided with tooth profiles 51 that engage with a slot 15. The tooth profiles 51 are engaged and fixed with limiting wings 17 on the inner wall of the slot 15, thereby bonding and fixing the core toothed portion 5 to the core yoke 4 through the tooth profiles 51. This stator core structure uses a separate stator core yoke 4 and core toothed portion 5, with several coils wound onto the insulating frame 1 through specific tooling connections.

[0030] This invention, by interlacing parallel conductive elements 2 on the frame 1, adjusts the winding 3 on the stator core from the conventional 12 individually wound segments to 4 continuously wound coils, thereby reducing the subsequent rewiring process. Furthermore, the parallel conductive elements 2 and slots 11 are designed on the insulating frame 1 on the stator core. The parallel conductive elements 2 are used for partial parallel winding, saving the circuit board used for logic paralleling compared to the traditional structure, while achieving the same output torque performance.
