Description

Technical Field

[0001] This utility model relates to the field of water pump rotor technology, and in particular to a highly adaptable motor rotor structure. Background Technology

[0002] The rotor of a water pump motor is a key component used in water pumps. It typically consists of a rotor core, rotor windings, and a shaft. The rotor core is generally made of stamped and stacked silicon steel sheets to form a magnetic circuit. The rotor windings generate a magnetic field, and the shaft transmits torque and supports the weight of the rotor. Driven by the rotating magnetic field generated by the stator, the rotor rotates at high speed, converting electrical energy into mechanical energy to drive the impeller of the water pump and transport water. The design and manufacturing of the rotor have a significant impact on the performance and efficiency of the water pump motor. Therefore, high-quality materials and precise manufacturing processes are required to ensure its stability and durability.

[0003] In traditional motor rotors, the permanent magnet is usually a single unit, fixedly mounted on the shaft. Once a part of the permanent magnet loses its magnetism or is damaged, the entire permanent magnet needs to be replaced, rather than a partial replacement. This increases maintenance costs, wastes resources, and reduces practicality. Therefore, we propose a motor rotor structure with strong applicability. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a motor rotor structure with strong applicability.

[0005] This utility model is achieved using the following technical solution: a highly adaptable motor rotor structure, including a rotating shaft, a mounting base fixedly connected to the surface of the rotating shaft, a dovetail groove formed on the surface of the mounting base, a dovetail block slidably connected to the inner wall of the dovetail groove, limit blocks provided on both sides of the left end of the dovetail block, a permanent magnet fixedly connected to the surface of the dovetail block, a fixing seat sleeved on the surface of the rotating shaft, a cross groove formed on the inner wall of the fixing seat, a mounting plate inserted into the inner wall of the cross groove, and a fastening bolt threadedly connected to the inner wall of the mounting plate.

[0006] The above technical solution divides the permanent magnet into multiple components in a modular design. When the permanent magnet needs to be replaced, the fastening bolts are removed to cancel the fixation of the dovetail block. Then the mounting plate is removed and the permanent magnet is slid out, which makes it easy to replace the permanent magnet individually without replacing the entire rotor, saving costs. At the same time, it is easy to replace permanent magnets of different thicknesses according to needs, which is suitable for different types of motors and application scenarios, thus improving applicability.

[0007] As a further improvement to the above scheme, the number of dovetail grooves is set to four, and the four dovetail grooves are arranged in a circle around the mounting base.

[0008] As a further improvement to the above scheme, the size of the dovetail groove is adapted to the size of the dovetail block, and the number of the dovetail blocks corresponds to the number of the dovetail groove.

[0009] With the above technical solution, after the dovetail block enters the dovetail groove, the permanent magnet is initially installed. At the same time, the dovetail groove prevents the permanent magnet from falling off when rotating at high speed.

[0010] As a further improvement to the above solution, a limiting groove is provided at the left end of the mounting base, and the surface of the limiting block contacts the inner wall of the limiting groove.

[0011] With the above technical solution, after the permanent magnet is initially installed, the limiting block will enter the interior of the limiting groove. At this time, the dovetail block cannot move downwards, thus playing a limiting role and facilitating subsequent installation.

[0012] As a further improvement to the above solution, the size of the limiting block is adapted to the size of the limiting groove.

[0013] As a further improvement to the above solution, the fixing seat is located at the left end of the mounting base, and the right end of the fastening bolt passes through the mounting plate and is threadedly connected to the inner wall of the dovetail block.

[0014] By using the above technical solution, the mounting plate can be removed by unfastening the fastening bolts. Since the dovetail groove is opened on the outer surface of the mounting base and the diameter of the mounting base is larger than that of the fixed base, the electromagnet can be removed without disassembling the fixed base, which improves the efficiency of subsequent replacement.

[0015] As a further improvement to the above scheme, the number of mounting plates and fastening bolts corresponds to the number of dovetail blocks.

[0016] The above technical solution uses a cross groove on the inner wall of the fixing seat to limit the position of the mounting plate, so that the threaded hole positions of the mounting plate and the dovetail block are aligned, which facilitates subsequent installation, eliminates the need to adjust the position of the mounting plate multiple times, and improves installation efficiency.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model, by setting up a mounting base, a dovetail block, a fixing base, a mounting plate, and fastening bolts, specifically removes the fastening bolts to cancel the fixation of the dovetail block, then removes the mounting plate and slides out the permanent magnet, which facilitates the individual replacement of the permanent magnet, reduces subsequent maintenance costs, reduces resource waste, and improves practicality. At the same time, it is easy to replace permanent magnets of different thicknesses according to needs, making it suitable for different types of motors and application scenarios, thus improving applicability.

[0019] This utility model, by setting up a mounting base, a dovetail block, a limiting block, a fixing base, a mounting plate, and fastening bolts, specifically, during the installation of the permanent magnet, the dovetail block is slid into the interior of the dovetail groove, while the limiting block enters the interior of the limiting groove, thus limiting the position of the permanent magnet. The dovetail groove limits the position of the dovetail block, ensuring the firmness of the permanent magnet installation and preventing it from falling off during high-speed rotation. Then, the mounting plate is inserted into the interior of the cross groove, which limits the position of the mounting plate and ensures that the mounting plate is aligned with the threaded hole of the dovetail block, facilitating installation and fixation. Finally, the permanent magnet is fixed to the mounting base by fastening bolts, improving the convenience of installation. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

A dovetail block 5 is slidably connected to the inner wall of the dovetail groove 3. Limiting blocks 6 are provided on both sides of the left end of the dovetail block 5. A permanent magnet 7 is fixedly connected to the surface of the dovetail block 5. A fixing seat 8 is sleeved on the surface of the rotating shaft 1. A cross groove 9 is formed on the inner wall of the fixing seat 8. A mounting plate 10 is inserted into the inner wall of the cross groove 9. A fastening bolt 11 is threadedly connected to the inner wall of the mounting plate 10. When the permanent magnet 7 loses its magnetism and needs to be replaced, the fixing of the dovetail block 5 is removed by disassembling the fastening bolt 11. Then, the mounting plate 10 is removed, and the permanent magnet 7 is slid out. This facilitates the individual replacement of the permanent magnet 7, reduces subsequent maintenance costs, reduces resource waste, and improves practicality. At the same time, it is convenient to replace permanent magnets 7 of different thicknesses according to needs, making it suitable for different types of motors and application scenarios, thus improving applicability.

[0030] There are four dovetail grooves 3, which are arranged in a circle around the mounting base 2.

[0031] The size of the dovetail groove 3 is matched with the size of the dovetail block 5, and the number of dovetail blocks 5 corresponds to the number of dovetail grooves 3. When installing the permanent magnet 7, the dovetail block 5 is slid into the interior of the dovetail groove 3. The dovetail groove 3 limits the position of the dovetail block 5, ensuring the firmness of the permanent magnet 7 installation and preventing it from falling off during high-speed rotation.

[0032] A limiting groove 4 is provided at the left end of the mounting base 2. The surface of the limiting block 6 contacts the inner wall of the limiting groove 4. When the limiting block 6 enters the interior of the limiting groove 4, it plays a limiting role in the position of the permanent magnet 7.

[0034] The fixing seat 8 is located at the left end of the mounting seat 2. The right end of the fastening bolt 11 passes through the mounting plate 10 and is threadedly connected to the inner wall of the dovetail block 5. The mounting plate 10 is inserted into the interior of the cross groove 9. The cross groove 9 limits the mounting plate 10 and ensures that the mounting plate 10 is aligned with the threaded hole of the dovetail block 5, which facilitates installation and fixing. Then, the permanent magnet 7 is fixed on the mounting seat 2 by the fastening bolt 11, which improves the convenience of installation.

[0035] The number of mounting plates 10 and fastening bolts 11 corresponds to the number of dovetail blocks 5.

[0036] The implementation principle of a highly adaptable motor rotor structure in this application embodiment is as follows: When the permanent magnet 7 loses its magnetism and needs to be replaced, the fastening bolts 11 are removed to release the fixation of the dovetail block 5. Then, the mounting plate 10 is removed, and the permanent magnet 7 is slid out, facilitating the individual replacement of the permanent magnet 7. This reduces subsequent maintenance costs, minimizes resource waste, and improves practicality. It also allows for the replacement of permanent magnets 7 of different thicknesses as needed, making it suitable for different types of motors and application scenarios, thus improving applicability. When installing the permanent magnet 7, the dovetail block... 5. Slide into the dovetail groove 3, and at the same time, the limiting block 6 enters the limiting groove 4, which limits the position of the permanent magnet 7. The dovetail groove 3 limits the dovetail block 5, ensuring the firmness of the permanent magnet 7 installation and preventing it from falling off during high-speed rotation. Then, the mounting plate 10 is inserted into the cross groove 9. The cross groove 9 limits the mounting plate 10, ensuring that the mounting plate 10 is aligned with the threaded hole of the dovetail block 5, which is convenient for installation and fixing. Then, the permanent magnet 7 is fixed on the mounting base 2 by the fastening bolt 11, which improves the convenience of installation.
