Description

Technical Field

[0001] The utility model relates to the technical field of motor stators, and particularly relates to a neodymium iron boron magnet stator structure for a motor. Background Art

[0002] The invention and development of motors have gone through multiple stages, and their foundation is mainly based on the principles of electromagnetism. In 1820, the Danish physicist Hans Oersted discovered the magnetic effect of electric current, which revealed the connection between electricity and magnetism. Subsequently, the British physicist Michael Faraday built the first experimental motor model in 1821 and discovered the electromagnetic induction phenomenon in 1831. These discoveries laid the theoretical foundation for the invention of motors. Early prototypes of electric motors included Barlow's wheel built by the British Peter Barlow in 1822 and the first true rotary electric motor created by the Prussian Moritz Jacobi in 1834. These early electric motors mainly worked based on the attraction of electromagnets or the interaction between magnets.

[0003] In the prior art, since the stator is fixed inside the motor, it may shake during long-term use, which will affect the performance and stability of the motor. The shaking of the stator may cause uneven magnetic fields, thereby affecting the efficiency and output power of the motor, and making the motor unstable during operation. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a neodymium iron boron magnet stator structure for a motor.

[0005] The utility model is realized by the following technical solutions: a neodymium iron boron magnet stator structure for a motor, including a motor protection housing, an inner wall of the motor protection housing is fixedly connected with a stator fixing block, an inner wall of the stator fixing block is fixedly connected with a stator, an inner wall of the motor protection housing is fixedly connected with an isolation housing, an inner wall of the motor protection housing is fixedly connected with a rotor, and a transmission shaft is rotatably connected to a front end of the motor protection housing.

[0006] As a further improvement of the above solution, the isolation housing is located inside the stator, and the rotor is located inside the isolation housing.

[0007] As a further improvement of the above solution, the transmission shaft is located in front of the rotor.

[0008] Through the above technical solution, by setting up the motor protection housing, it provides protection and support for the internal components, preventing external physical damage and electromagnetic interference, ensuring the stable operation of the motor. The stator fixing block fixes the stator, making it more stable inside and preventing shaking or displacement caused by the operation of the motor. The stator uses neodymium iron boron magnets, which have a high magnetic energy product and can provide a strong magnetic field within a small volume, improving the efficiency of the motor. The isolation housing isolates the stator and the rotor, reducing the mutual interference of the magnetic fields and improving the stability and reliability of the motor operation.

[0009] As a further improvement of the above solution, a bolt fixing block is fixedly connected to the inner wall of the motor protection housing. A fixing bolt is threadedly connected to the inner wall of the bolt fixing block, and a rear cover is threadedly connected to the surface of the fixing bolt.

[0010] As a further improvement of the above solution, the fixing bolt is snap-fitted with the bolt fixing block. The number of the fixing bolts is set to four, and the four fixing bolts are located on the inner wall of the bolt fixing block. The bolt fixing block is located behind the stator.

[0011] Through the above technical solution, by setting up the bolt fixing block and the fixing bolt, it is used to fix the rear cover and protect the internal components from the outside.

[0012] As a further improvement of the above solution, a motor support base is fixedly connected to the surface of the motor protection housing, and a threaded hole is opened on the upper surface of the motor support base.

[0013] As a further improvement of the above solution, the number of the threaded holes is set to two, and the two threaded holes are symmetrically arranged with the motor support base as the center.

[0014] Through the above technical solution, by setting up the motor support base and fixing the motor through the threaded hole, it can be stably installed on the external device to ensure the normal operation of the motor.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] The utility model provides protection and support for internal parts by setting up a motor protection housing. Due to its strong structure, it can effectively prevent external physical damage and electromagnetic interference, enabling the internal parts to work stably. The stator fixing block fixes the stator, making the stator more stable inside. The stator is a neodymium iron boron magnet, which has an extremely high magnetic energy product. This means that they can provide a strong magnetic field within a smaller volume. They can resist the influence of external magnetic fields and maintain their original magnetization state. Due to its fixing effect, the stator is more stable inside and will not shake or displace due to the operation of the motor. The isolation housing isolates the stator and the rotor. Due to its isolation effect, the magnetic fields between the stator and the rotor will not interfere with each other, thereby improving the operating stability and reliability of the motor. The rotor rotates inside the stator. Due to its rotational movement, a rotating magnetic field is generated, enabling the motor to output mechanical energy. The transmission shaft transmits power. The bolt fixing block and the fixing bolt are used to fix the rear cover. Due to its fixing effect, the rear cover can be firmly fixed on the motor protection housing, thereby protecting the internal parts from the outside. The motor support base fixes the device above through threaded holes. Due to its support effect, the motor can be stably installed on external equipment, thereby ensuring the normal operation of the motor. Brief Description of the Drawings
