Description

Technical Field

[0001] This utility model relates to the field of motor installation technology, specifically a mounting base for a permanent magnet synchronous motor. Background Technology

[0002] Permanent magnet synchronous motors (PMSMs), as a type of high-efficiency, high-power-density electric motor, are widely used in industrial drives, new energy vehicles, wind power generation, and precision control. Their core feature lies in the use of high-performance permanent magnets as the rotor excitation source, replacing the excitation windings and slip ring brush systems required by traditional electrically excited motors. This not only significantly simplifies the motor's structure but also effectively improves operational reliability and maintenance convenience. Since no excitation current is required, the motor experiences no excitation losses during operation, further improving energy conversion efficiency and achieving higher output power density within the same volume.

[0003] In practical engineering applications, permanent magnet synchronous motors require a mounting base to achieve a reliable connection with the equipment foundation or support. However, most existing installation methods remain at the level of rigid fixation, that is, the motor housing is directly fixed to the support platform at a predetermined position using bolts. Although this type of installation structure has a certain degree of structural stability, it exposes many limitations in actual use: First, once the installation position is fixed, it is difficult to adjust, and it cannot adapt to the requirements of motor shaft alignment accuracy under different working conditions, which is particularly inconvenient in situations requiring frequent replacement or adjustment; Second, current bases generally lack height adjustment and leveling functions. When there are slight unevennesses on the mounting surface or differences in foundation settlement, additional stress can easily be generated in the coupling between the motor and the load, leading to increased vibration, accelerated bearing wear, or even shaft breakage and other potential failures; Third, in complex environments or under varying terrain conditions (such as outdoor equipment, mobile platforms, etc.), traditional bases cannot meet the needs of rapid installation and flexible adaptation, limiting the versatility and deployment efficiency of the motor system.

[0004] Therefore, with the increasing level of automation and the development of intelligent equipment, users have placed higher demands on the flexibility, adjustability, and environmental adaptability of motor mounting systems. There is an urgent need for a new type of permanent magnet synchronous motor mounting base structure that can achieve convenient position adjustment, height compensation, and level calibration functions while ensuring load-bearing rigidity and operational stability. This would improve overall assembly efficiency, extend equipment lifespan, and enhance the system's adaptability in diverse application scenarios. Utility Model Content

[0005] To address the problem of inconvenient adjustment of the permanent magnet synchronous motor mounting base in the background art, this utility model proposes a permanent magnet synchronous motor mounting base.

[0006] The technical solution of this utility model is as follows: the permanent magnet synchronous motor mounting base includes a base, the upper surface of which has two symmetrically arranged mounting slots, each mounting slot has a through slot on both sides, and each through slot has a limiting slot on one side of its bottom; a slider is slidably installed in the mounting slots, through slots and limiting slots, and the slider is connected to the permanent magnet synchronous motor by mounting bolts; multiple fixing holes are evenly opened at the bottom of the mounting slots, and the mounting bolts can be inserted into the fixing holes to lock the position of the slider.

[0007] A further technical solution of this utility model is that the slider includes a mounting plate slidably disposed in the mounting groove, the mounting plate having mounting holes for mounting bolts to pass through; connecting strips are fixed on both sides of the bottom of the mounting plate, and limiting strips are provided on the bottom outer sides of the two connecting strips; the connecting strips are slidably disposed in the through groove, and the limiting strips are slidably disposed in the limiting groove.

[0008] A further technical solution of this utility model is that multiple positioning grooves are opened on both sides of the upper surface of the base, and the positions of the positioning grooves correspond one-to-one with the fixing holes.

[0009] A further technical solution of this utility model is that support blocks are fixedly installed at the four corners of the bottom of the base, and adjustment blocks are threadedly connected to the outer surface of the support blocks.

[0010] A further technical solution of this utility model is that multiple anti-slip grooves are formed on the outer surface of the adjustment block.

[0011] A further technical solution of this utility model is that the base, support block and adjustment block are coaxially provided with through holes, and fixing bolts are installed in the through holes.

[0012] A further technical solution of this utility model is that the slider adjusts the horizontal position of the permanent magnet synchronous motor on the base by sliding, and after adjustment, it is fixed by mounting bolts and fixing holes.

[0013] A further technical solution of this utility model is that the height and level of the base are adjusted by rotating the adjusting block via a thread.

[0014] A further technical solution of this utility model is that the positioning groove is used to assist in the alignment operation of the mounting bolt and the fixing hole.

[0015] A further technical solution of this utility model is that the fixing bolt passes through the through hole to fix the base to the mounting base surface.

[0016] The advantages of this utility model are as follows: By setting the permanent magnet synchronous motor and the slider to be connected and fixed by mounting bolts, and setting the slider to be slidably connected to the base, and setting multiple fixing holes evenly opened at the bottom of the mounting groove for installing the mounting bolts, it is easy for the user to adjust the working position of the permanent magnet synchronous motor, thus achieving the purpose of easy adjustment. Furthermore, a support block is set at the bottom of the base, and an adjustment block is set on the outer surface of the support block. Through holes are opened in the base, support block and adjustment block for installing fixing bolts, which makes it easy for the user to adjust the height and level of the base, thereby facilitating the installation and fixing of the permanent magnet synchronous motor.

A slider 2 for mounting a permanent magnet synchronous motor 3 is slidably installed inside the mounting slots 11, through slots 12, and limiting slots 13. The permanent magnet synchronous motor 3 is connected to the slider 2 via mounting bolts 20. Multiple fixing holes 111 for mounting the mounting bolts 20 are evenly provided at the bottom of the mounting slots 11. When the permanent magnet synchronous motor 3 is mounted on the slider 2 via the mounting bolts 20, its position can be adjusted using the slider 2. After adjustment to a suitable position, the mounting bolts 20 continue downward into the corresponding fixing holes 111, thereby installing and fixing the slider 2 and the permanent magnet synchronous motor 3 mounted thereon.

[0027] The slider 2 includes a mounting plate 21 that is slidably installed inside the mounting groove 11. The mounting plate 21 has mounting holes 211 for installing mounting bolts 20. Connecting strips 22 are fixedly installed on both sides of the bottom of the mounting plate 21. Limiting strips 23 are fixedly installed on the bottom of the outer sides of the two connecting strips 22. The connecting strips 22 are slidably installed inside the through groove 12, and the limiting strips 23 are slidably installed inside the limiting groove 13.

[0028] Multiple positioning grooves 14 are provided on both sides of the upper surface of the base 1. The positioning grooves 14 correspond to the positions of the fixing holes 111, so that the user can adjust the mounting bolts 20 to be aligned with the fixing holes 111 for subsequent installation and fixing.

[0029] Support blocks 15 are fixedly installed at the four corners of the bottom of the base 1. Adjustment blocks 16 are threaded on the outer surface of the support blocks 15. Multiple anti-slip grooves 161 are opened on the outer surface of the adjustment blocks 16. Through holes 17 are opened inside the base 1, support blocks 15 and adjustment blocks 16. Fixing bolts 18 are installed inside the through holes 17. Fixing bolts 18 are used to connect to the ground or other equipment to install and fix the base 1.

[0030] Working principle: First, install the base 1 to the designated position and adjust its height and flatness using the adjusting block 16. Then, install the fixing bolt 18 inside the through hole 17 to fix the base 1. Next, install the permanent magnet synchronous motor 3 on the slider 2 using the mounting bolt 20. Slide the slider 2 to adjust the permanent magnet synchronous motor 3 to a suitable working position. Align one end of the slider 2 with the positioning groove 14. Finally, continue to lower the mounting bolt 20 to enter the corresponding fixing hole 111 to install and fix the permanent magnet synchronous motor 3.

[0031] In this utility model, the permanent magnet synchronous motor 3 and the slider 2 are connected and fixed by mounting bolts 20, and the slider 2 is slidably connected to the base 1. Multiple fixing holes 111 for mounting bolts 20 are evenly opened at the bottom of the mounting groove 11, which makes it easy for the user to adjust the working position of the permanent magnet synchronous motor 3, thus achieving the purpose of easy adjustment. A support block 15 is set at the bottom of the base 1, and an adjustment block 16 is set on the outer surface of the support block 15. Through holes 17 are opened in the base 1, the support block 15 and the adjustment block 16 to install fixing bolts 18, which makes it easy for the user to adjust the height and level of the base 1, thereby facilitating the installation and fixing of the permanent magnet synchronous motor 3.
