Description

Technical Field

[0001] This utility model relates to the field of permanent magnet synchronous motor technology, and in particular to a high-efficiency and stable permanent magnet synchronous motor terminal block assembly structure. Background Technology

[0002] Currently, most six-phase redundant permanent magnet synchronous motors use an integrated structure of a six-phase terminal block and a plastic terminal block. This structure requires a small number of parallel branches and a 50 / 50 spatial distribution of inductors, which is easy to achieve in terms of manufacturing. However, if the number of parallel circuits in the motor increases and the inductors are spatially symmetrical, the span between the six-phase terminal block and the GND terminal block becomes large, and the circumferential distance is limited, increasing both the manufacturing difficulty and the outer diameter of the motor housing. Utility Model Content

[0003] The main purpose of this utility model is to provide a high-efficiency and stable permanent magnet synchronous motor terminal block assembly structure, which can effectively solve the problems of high processing difficulty and low production efficiency.

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

[0005] A high-efficiency and stable permanent magnet synchronous motor terminal block assembly structure includes a terminal block plastic component. The terminal block plastic component is provided with a center point terminal block one and a center point terminal block two. The terminal block plastic component is also provided with a U-phase terminal block one, a V-phase terminal block one, a W-phase terminal block one, a U-phase terminal block two, a V-phase terminal block two, and a W-phase terminal block two.

[0006] Preferably, the first U-phase terminal block, the first V-phase terminal block, and the first W-phase terminal block are symmetrically arranged with the second U-phase terminal block, the second V-phase terminal block, and the second W-phase terminal block, respectively.

[0007] Preferably, a plurality of inverted L-shaped brackets are fixed to the lower part of the outer surface of the plastic part of the terminal block, and a fixing hook is provided on the lower part of the vertical part of the plurality of inverted L-shaped brackets near the central axis of the plastic part of the terminal block.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] 1. This utility model adopts an integrated molding design for the terminal block plastic parts, which eliminates the need to install individual terminal blocks inside the terminal block plastic parts during the production of the terminal block assembly, thus facilitating the production of the device. At the same time, the integrated injection molding of the terminal block and the terminal block plastic parts not only increases the distance between multiple terminal blocks during motor design and wiring, avoiding interference between parts, but also reduces the complexity of winding and terminal welding in the process, thereby improving production efficiency.

[0010] 2. This utility model adopts an inverted L-shaped bracket and a fixing hook design, which can easily fix the plastic parts of the terminal block to the insulating frame of the motor, prevent the movement of multiple terminal blocks in position and height, and make the device more stable during use.

[0011] 3. This utility model adopts an integrated cable outlet structure, which can reduce the number of parallel circuits and allow the inductor space to be distributed in half, which facilitates the processing of the motor structure. In addition, the span of multiple terminal blocks is small and the circumferential distance is not restricted, resulting in a smaller diameter of the motor housing and reducing the difficulty of motor processing.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figure 1 and Figure 3 As shown, a high-efficiency and stable permanent magnet synchronous motor terminal block assembly structure includes a terminal block plastic component 1. The terminal block plastic component 1 is made of insulating plastic material, which can insulate multiple terminal blocks and prevent multiple terminal blocks from contacting each other during motor operation, thereby causing a short circuit and affecting the normal operation of the motor. The terminal block plastic component 1 adopts an integrated structure, which can reduce the difficulty of the process and reduce the equipment on the production line. Compared with the existing six-phase inductor space half terminal block, it can improve the stability of the motor during use.

[0018] Furthermore, to facilitate the installation of the motor terminal block assembly, multiple terminal blocks are individually processed and formed during production. Then, these terminal blocks are placed in different positions, and during the injection molding of the terminal block plastic part 1, the multiple terminal blocks are fixed inside the terminal block plastic part 1. This eliminates the need to install individual terminal blocks inside the terminal block plastic part 1 during the production of the terminal block assembly, simplifying the production of the device. At the same time, the integrated injection molding of the terminal block and the terminal block plastic part 1 not only increases the distance between the multiple terminal blocks during motor design wiring, avoiding interference between parts, but also reduces the complexity of winding and terminal welding in the process, improving production efficiency.

[0019] Furthermore, to facilitate the fixing of the plastic part 1 of the terminal block to the insulating frame of the motor, such as... Figure 2 As shown, multiple inverted L-shaped brackets 11 are fixed to the lower part of the outer surface of the plastic part 1 of the terminal block. The lower part of the vertical part of the multiple inverted L-shaped brackets 11 near the central axis of the terminal block plastic part 1 is provided with a fixing hook 12. The multiple inverted L-shaped brackets 11 and the fixing hook 12 are formed together during the injection molding of the terminal block plastic part 1, which can facilitate the fixing of the terminal block plastic part 1 to the insulating frame of the motor, prevent the position and height of the multiple terminal blocks from moving, and make the device more stable during use.

[0020] In addition, the plastic part 1 of the terminal block is also equipped with a center point terminal block 2, a U-phase terminal block 3, a V-phase terminal block 4, a W-phase terminal block 5, a center point terminal block 6, a U-phase terminal block 7, a V-phase terminal block 8, and a W-phase terminal block 9. The U-phase terminal block 3, V-phase terminal block 4, and W-phase terminal block 5 are symmetrically arranged with the U-phase terminal block 7, V-phase terminal block 8, and W-phase terminal block 9, respectively. This further increases the number of parallel circuits of the motor and achieves spatial symmetry of the inductors. The integrated wiring structure requires a small number of parallel circuits and a motor with inductors distributed in half, which facilitates the processing of the structure. Furthermore, the span between the multiple terminal blocks is small and the circumferential distance is not restricted, resulting in a smaller diameter of the motor housing and reducing the difficulty of motor processing.

[0021] The specific implementation method of this embodiment is as follows: During the production of the motor terminal block structure, multiple terminal blocks are produced separately, and then the multiple terminal blocks are placed in different positions. During the injection molding of the terminal block plastic part 1, the multiple terminal blocks are fixed inside the terminal block plastic part 1, so that during the production of the terminal block assembly, it is not necessary to install individual terminal blocks inside the terminal block plastic part 1, which facilitates the operation of the device. Then, the molded terminal block structure is installed on the insulating frame of the motor.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
