Detailed Implementation

[0023] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0024] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Figures 1-6As shown, in one embodiment of this utility model, a reluctance motor is disclosed, comprising an upper housing 1, a base housing 2, a lower housing 3, a stator assembly 4, and a rotor assembly 5. The upper housing 1 and the lower housing 3 are respectively disposed at both ends of the base housing 2. The base housing 2 is provided with a mounting cavity 21, and the stator assembly 4 is disposed within the mounting cavity 21. The rotor assembly 5 includes a rotating shaft 51 and a magnetic ring element 52. The magnetic ring element 52 is disposed on the rotating shaft 51, and both ends of the rotating shaft 51 are respectively connected to the upper housing 1 and the lower housing 3, and pass through the upper housing 1 and / or the lower housing 3. The stator assembly 4 includes stator winding arms 41 and stator windings 42. Multiple stator winding arms 41 are provided, and a winding bracket 43 is provided on the stator winding arms 41. A winding groove 431 is provided on the winding bracket 43, and the stator windings 42 are wound on the winding groove 431. This embodiment, through the structural design of the upper housing 1, base housing 2, and lower housing 3, provides robust support and protection for the internal components of the motor. Furthermore, this split structure facilitates motor assembly and subsequent maintenance, reducing repair difficulty and costs. Regarding the stator assembly 4, multiple stator arms 41, along with their winding supports 43 and winding slots 431, provide precise and stable winding space for the stator windings 42. The optimized winding layout allows the stator windings 42 to be wound more regularly and tightly within the winding slots 431, effectively improving the motor's electromagnetic conversion efficiency. Moreover, the regular winding arrangement helps reduce electromagnetic interference, lowering noise generated during motor operation and improving the motor's stability and quietness. The rotor assembly 5 is mounted on the shaft 51 via a magnetic ring element 52. The shaft 51 connects to both ends of the upper housing 1 and the lower housing 3, passing through a portion of the housing, ensuring stable rotor rotation within the motor. Simultaneously, it guarantees a reasonable magnetic circuit distribution between the magnetic ring element 52 and the stator assembly 4, contributing to improved torque output and operating performance of the motor. Overall, this reluctance motor solution achieves efficient, stable, and low-noise operation through the coordinated operation of its various components.

[0026] The upper housing 1 is provided with a first fixed inner ring 11, and the first fixed inner ring 11 is provided with a first rotary connecting element 12. The lower housing 3 is provided with a second fixed inner ring 31, and the second fixed inner ring 31 is provided with a second rotary connecting element 32. The two ends of the rotating shaft 51 are respectively connected to the first rotary connecting element 12 and the second rotary connecting element 32. In this embodiment, the connection between the first fixed inner ring 11 and the first rotary connecting element 12 thereon, and the second fixed inner ring 31 and the second rotary connecting element 32 thereon, in conjunction with the connection between the two ends of the rotating shaft 51, provides a stable and flexible mechanical support structure for the motor rotating shaft 51. The rotary connecting element is a bearing, which ensures the precise rotation of the rotating shaft 51 during motor operation. The first rotary connecting element 12 and the second rotary connecting element 32 can effectively reduce the friction and vibration generated by the rotating shaft 51 during high-speed rotation, reduce mechanical loss, and thus improve the operating efficiency of the motor. On the other hand, the precise connection design makes the rotation of the rotating shaft 51 more stable, ensuring the stability of the magnetic field conversion of the reluctance motor. Because the working principle of a reluctance motor relies on the orderly changes of a magnetic field, the stable rotation of the shaft 51 helps to maintain the precise switching of the magnetic field, enabling the motor to work efficiently according to the predetermined electromagnetic conversion mode.

[0027] The upper housing 1 is provided with a first mating groove 13, and a first mating positioning platform 14 is provided on the first mating groove 13. The first mating groove 13 is used to insert and cover one end of the base housing 2, and the first mating positioning platform 14 is used for assembling and positioning the base housing 2. The first mating positioning platform 14 is provided with a first countersunk hole 141 for fixed connection with the base housing 2 by screws. In this embodiment, the first mating groove 13 inserts into and covers one end of the base housing 2, which not only achieves a stable nesting in the mechanical structure, but also effectively protects the base housing 2 and reduces the impact and damage to it from external factors. The precise positioning function of the first mating positioning platform 14 greatly improves the accuracy and consistency of the assembly of the base housing 2, ensuring that the relative positions between the components of the reluctance motor are accurate, which is crucial for the stability of the magnetic field distribution inside the motor. The fixed connection with the base housing 2 by screws through the first countersunk hole 141 is firm and reliable, which can effectively resist the vibration and impact generated during the operation of the motor and prevent the components from loosening. When the reluctance motor is running at high speed, a stable connection can ensure that the components work together and reduce energy loss and abnormal noise caused by unstable connection.

[0028] The upper housing 1 has multiple through slots 15 at its end, one end of which connects to and corresponds to the mounting cavity 21 for heat dissipation of the stator assembly 4. In this embodiment, the stator assembly 4 generates a large amount of heat during the operation of the reluctance motor. If this heat cannot be dissipated effectively and in a timely manner, the temperature of the stator assembly 4 will become too high, thereby affecting the performance and efficiency of the motor and even shortening its service life. The through slots 15 cleverly provide an efficient channel for heat dissipation of the stator assembly 4. Through the through slots 15, hot air can be smoothly discharged from the mounting cavity 21, ensuring that the stator assembly 4 operates in a relatively stable temperature environment.

[0029] The lower housing 3 is provided with a second mating groove 33, and a second mating positioning platform 34 is provided on the second mating groove 33. The second mating groove 33 is used to insert and cover one end of the base housing 2, and the second mating positioning platform 34 is used for assembling and positioning the base housing 2. The second mating positioning platform 34 is provided with a second countersunk hole 341 for fixing to the base housing 2 with screws. In this embodiment, by inserting and covering one end of the base housing 2 with the second mating groove 33, the tight fit design can effectively enhance the stability of the overall structure of the reluctance motor, reduce the loosening of components that may be caused by vibration and other factors, and ensure the accuracy of the relative positions of each component during motor operation. The second mating positioning platform 34 not only provides precise positioning for the assembly of the base housing 2, ensuring the accuracy and repeatability of installation, but also the second countersunk hole 341 on it is used to fix the base housing 2 with screws, which is reliable and stable. When the reluctance motor is running, it can effectively resist the internal electromagnetic force of the motor and various forces brought by the external environment, ensuring the stable operation of the motor.

[0030] The stator winding arm 41 extends from the base housing 2 toward the axis of the mounting cavity 21. The winding bracket 43 is an insulating bracket and is mounted on the stator winding arm 41. In this embodiment, the reasonable extension of the stator winding arm 41 helps to optimize the magnetic field distribution inside the motor, allowing magnetic lines of force to pass through each component more evenly and efficiently, reducing magnetic field loss and improving the magnetic conversion efficiency of the motor. The installation of the insulating winding bracket 43 further ensures the safety and stability of the motor operation. It can effectively prevent unnecessary leakage and short circuits of current in the stator winding arm 41, avoiding motor damage caused by electrical faults. At the same time, the insulation characteristics can also reduce electromagnetic interference, improve the overall anti-interference capability of the motor, and ensure that the reluctance motor can operate accurately and stably in complex electrical environments.

[0031] The winding bracket 43 has an assembly slot 432 at its end, which is used to engage with both ends of the base housing 2. In this embodiment, from the perspective of mechanical structural stability, it greatly enhances the connection stability between the winding bracket 43 and the base housing 2, ensuring that the winding bracket 43 can maintain a precise position even under the vibration environment generated by the high-speed operation of the motor, reducing the risk of failure due to loosening. Secondly, in terms of electrical performance, the stable engaging structure helps to ensure the accurate relative position of the windings, avoiding uneven magnetic field distribution caused by positional deviations, thereby improving the overall efficiency and performance of the reluctance motor. It simplifies the motor assembly process, improves production efficiency, and also facilitates subsequent maintenance and repair work, reducing maintenance costs.

[0032] See Figure 3 As shown, a magnetic induction assembly 6 is provided at the bottom of the lower housing 3. The magnetic induction assembly 6 includes a magnetic ring sleeve 61, a Hall ring 62, and a Hall plate 63. The magnetic ring sleeve 61 is disposed at one end of the rotating shaft 51, the Hall ring 62 is disposed in the lower housing 3 and located on the outer periphery of the magnetic ring sleeve 61, and the Hall plate 63 is disposed on one side of the Hall ring 62. Specifically, a locking element 511 is provided at the end of the rotating shaft 51, which is used to lock and fix the magnetic ring sleeve 61 on the rotating shaft 51. In this embodiment, the magnetic ring sleeve 61 rotates synchronously with the rotating shaft 51, the Hall ring 62 is stationary in the lower housing 3 and located on the outer periphery of the magnetic ring sleeve 61, and the Hall plate 63 is located on one side of the Hall ring 62. The three work together. When the rotating shaft 51 drives the magnetic ring sleeve 61 to rotate, the magnetic field distribution around the magnetic ring sleeve 61 changes regularly. This change is sensed by the Hall ring 62, and then the Hall plate 63 converts the magnetic field signal into an electrical signal for output. Through the magnetic induction component 6, the reluctance motor can accurately acquire the position and speed information of the rotating shaft 51. On the one hand, based on this precise data feedback, the motor's control system can adjust the motor's operating parameters in real time, achieving precise control of the motor's speed, torque, etc., thereby improving the stability and efficiency of the motor's operation. On the other hand, the locking element 511 securely locks the magnetic ring sleeve 61 to the end of the rotating shaft 51, ensuring the relative positional accuracy between the magnetic ring sleeve 61 and the rotating shaft 51. This allows the magnetic induction component 6 to work continuously and reliably, ensuring the long-term stable and efficient operation of the reluctance motor.

[0033] The rotating shaft 51 is equipped with a positioning step 512 and a fixing ring. The positioning step 512 is used to position the magnetic ring element 52, and the fixing ring is used to fix the end of the magnetic ring element 52. In this embodiment, the positioning step 512 precisely positions the magnetic ring element 52, ensuring that the magnetic ring is in a precise position during motor operation. This greatly optimizes the magnetic circuit structure, enabling efficient and stable distribution of magnetic flux, reducing magnetic leakage, thereby improving the electromagnetic conversion efficiency of the reluctance motor, reducing energy loss, and enhancing the overall performance of the motor. The fixing ring firmly fixes the end of the magnetic ring element 52, effectively preventing the magnetic ring from shifting or loosening when the motor rotates at high speed, vibrates, or is subjected to external impacts. This ensures the stability of the magnetic ring element 52's operation, maintains the reliability of motor operation, and avoids magnetic field disturbances caused by magnetic ring displacement.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
