Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of permanent magnet synchronous motors, in particular to a novel segmented permanent magnet synchronous motor wiring board component structure. Background Art
[0002] At present, the output structure of the six-phase redundant permanent magnet synchronous motor is mostly an integrated structure of a six-phase terminal block and a plastic terminal block. This output structure is suitable for motors with shorter wiring PINs and is easy to implement in terms of technology. However, if the output PIN of the motor is too long, the integrated structure will waste more raw materials during the processing of the PIN, increasing the cost. As the injection molding length increases, the process will not be able to accurately guarantee the position of the PIN, resulting in the bending and deformation of the PIN, which ultimately causes a large error between the output PIN position and the design requirements and cannot meet the motor design requirements.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0017] like Figure 1 and Figure 3As shown, a novel segmented permanent magnet synchronous motor terminal board component structure includes a terminal board plastic part 1. The terminal board plastic part 1 is made of insulating plastic material and can insulate multiple terminal boards to prevent multiple terminal boards from contacting each other when the motor is working, thereby causing a short circuit and affecting the normal operation of the motor. The terminal board plastic part 1 adopts an integrated structure, which can reduce the process difficulty and reduce the equipment of the production line. Compared with the existing terminal board with half the six-phase inductance space, it can improve the stability of the motor when in use. A plurality of inverted L-shaped brackets 12 are fixed on the outer surface of the terminal board plastic part 1. A locking hook 13 is fixed at the lower part of one end of the vertical part of the inverted L-shaped bracket 12 close to the central axis of the terminal board plastic part 1, which can facilitate the terminal board plastic part 1 to be fixed on the insulating frame of the motor to prevent the movement of the position and height of multiple terminal boards, so that the motor is more stable when in use.
[0018] like Figure 4 As shown, the inside of the terminal board plastic part 1 is fixed with W-phase terminal board 2 9, V-phase terminal board 2 8, U-phase terminal board 2 7, W-phase terminal board 1 5, V-phase terminal board 1 4, and U-phase terminal board 1 3 in clockwise direction, and the inside of the terminal board plastic part 1 is symmetrically fixed with center point terminal board 1 2 and center point terminal board 2 6 at the bottom, U-phase terminal board 1 3, V-phase terminal board 1 4, and W-phase terminal board 1 5 are arranged from bottom to top, U-phase terminal board 1 3 is symmetrically arranged with U-phase terminal board 2 7, V-phase terminal board 1 4 is symmetrically arranged with V-phase terminal board 2 8, and W-phase terminal board 1 5 is symmetrically arranged with W-phase terminal board 2 9, which further increases the number of parallel circuits of the motor and realizes spatial symmetry of the inductance. Compared with the split-type outlet structure, the integrated design of the six-phase terminal board and the terminal board plastic part 1 uses fewer molds, reduces the expensive mold costs, and reduces the production cost.
[0019] Furthermore, if Figure 2 As shown, six-phase PINs 10 are fixed on the upper ends of U-phase terminal board 13, V-phase terminal board 14, W-phase terminal board 15, U-phase terminal board 27, V-phase terminal board 28, and W-phase terminal board 29, and a PIN injection molded part 11 is fixed on the outer surfaces of multiple six-phase PINs 10 near the side of U-phase terminal board 13, and a PIN injection molded part 11 is also fixed on the outer surfaces of multiple six-phase PINs 10 near the side of W-phase terminal board 29. In particular, when the six-phase PINs 10 are produced, they need to be processed separately. When the PIN injection molded part 11 is produced by injection molding, the multiple six-phase PINs 10 need to be fixed so that the PIN injection molded part 11 allows the multiple six-phase PINs 10 to be fixed in the PIN injection molded part 11 during injection molding. The multiple terminal boards and the terminal board plastic part 1 adopt an integrated injection molding design, which can increase the distance between the various components when designing and wiring the motor, avoid interference between the various components, reduce the complexity of winding and terminal welding in the process, and improve the work efficiency during production.
[0020] Among them, multiple terminal blocks are processed separately during production, and then the terminal block plastic part 1 allows multiple terminal blocks to be fixed in the terminal block plastic part 1 during injection molding, and then the PIN injection molded part 11 is installed on the end cover, and then the PIN injection molded part 11 and the terminal block plastic part 1 are hot-melt welded together, which can prevent the position of the six-phase PIN 10 from shifting and ensure the high stability of the six-phase PIN 10. The terminal block plastic part 1 places multiple terminal blocks in different positions during injection molding, so that the motor terminal block assembly structure does not need to fix a single terminal block in the terminal block plastic part 1 during production, which facilitates the production of the terminal block assembly. At the same time, the terminal block and the terminal block plastic part 1 are integrally injected, which not only increases the distance between multiple terminal blocks during motor design and wiring, but also avoids interference between parts.
[0021] The specific implementation of this embodiment is as follows: when the motor terminal board structure is produced, multiple terminal boards are first pressed and formed separately, and then the multiple terminal boards are placed in sequence, and the multiple terminal boards are fixed in the terminal board plastic part 1 by injection molding, which can increase the distance between the various components when the motor is designed and wired, avoid interference between the various components, and reduce the complexity of winding and terminal welding in the process, thereby improving the work efficiency during production;
[0022] At the same time, the PIN injection molded part 11 is produced again in the same way as the terminal board plastic part 1. After the production of the PIN injection molded part 11 is completed, the six-phase PIN 10 is fixed on the terminal board of the corresponding phase line.
[0023] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
