Description

Technical Field

[0001] The utility model relates to the field of motor processing and manufacturing, in particular to a motor stator and rotor sheet structure without rivet points. Background Art

[0002] In a motor, the stator is the static part of the motor, and its windings are usually composed of insulated coils fixed to the motor housing or frame. The stator winding generates a rotating magnetic field through current, which interacts with the magnetic field of the rotor to generate torque and drive the motor. The rotor is the rotating part of the motor, which usually includes the rotor core and windings. The rotor winding can be in the form of bar windings, wire windings or permanent magnets. The interaction between the rotor windings and the stator windings generates torque to make the motor rotate. Rotor motors are common in DC motors, synchronous motors, and permanent magnet synchronous motors.

[0003] The main structural part of the stator is usually made of silicon steel sheets or other materials with high magnetic permeability. It is used to provide a magnetic circuit and support the stator winding. The winding is a conductor wound on the stator core, usually copper wire or aluminum wire. Appropriate insulating materials are required between the windings and between the windings and the core to prevent the windings from short-circuiting or unnecessary contact with the core. The main structural part of the rotor is similar to the stator core. It is used to provide a magnetic circuit and support the rotor winding. The rotor requires appropriate bearing support to ensure that it can rotate freely.

[0004] However, the traditional connection structure of the stator and rotor is usually riveted, and rivet points are set inside the stator and rotor structure to connect them. Traditional riveting may introduce thermal stress and material deformation, causing motor operation failure. At the same time, the assembly process is relatively cumbersome, reducing its practicality. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a rivet-free motor stator and rotor sheet structure, aiming to improve the problem that riveting in traditional stators and rotors may introduce thermal stress and material deformation, leading to motor operation failures, and the assembly process is relatively cumbersome, reducing its practicality.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rivet-free motor stator and rotor sheet structure, including a stator base, a plurality of heat dissipation holes are opened inside the stator base, a plurality of heat dissipation channels are opened inside the stator base, a stator core is fixedly connected to the outer shell of the stator base, the stator core is spiral-shaped, a stator winding is arranged between the stator core and the stator base, a plurality of magnetic rings are fixedly connected to the inner wall of the stator base, a rotor assembly is arranged inside the stator base, and the rotor assembly is used to drive the motor.

[0007] Furthermore, the rotor assembly includes a rotor main shaft, and the rotor main shaft is slidably connected inside the stator frame.

[0008] Furthermore, a rotor core is sleeved on the outer wall of the rotor main shaft.

[0009] Furthermore, the rotor core is spiral-shaped.

[0010] Furthermore, a plurality of magnetic rings 2 are fixedly connected to the outer wall of the rotor main shaft.

[0011] Furthermore, the second magnetic ring interacts with the first magnetic ring.

[0012] Furthermore, a bidirectional shaft is fixedly connected inside the rotor main shaft.

[0013] Furthermore, rotor windings are arranged on both sides of the outer wall of the rotor main shaft.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, the stator and the rotor are aligned and fixed by magnetically adsorbing the magnetic ring 1 inside the stator frame and the magnetic ring 2 inside the rotor main shaft. This method not only avoids the thermal stress and material deformation that may be introduced by traditional riveting, but also simplifies the assembly process and improves the reliability of the motor.

[0016] 2. In the present invention, the magnetic ring 2 maintains magnetic positioning with the stator frame to ensure stable structural connection. The rotor winding is used to receive the induced current in the stator and generate a rotating magnetic field. The connection between the bidirectional shaft and the rotor main shaft provides the rotor's rotation axis, so that the rotor can rotate freely inside or outside the stator. This support ensures the normal operation of the motor or generator, so that the rotor can effectively interact with the magnetic field between the stator windings. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a rivet-free motor stator and rotor sheet structure, including a stator base 1, a plurality of heat dissipation holes 4 are opened inside the stator base 1, a plurality of heat dissipation channels 5 are opened inside the stator base 1, a stator core 2 is fixedly connected to the outer shell of the stator base 1, the stator core 2 is spiral-shaped, a stator winding 3 is arranged between the stator core 2 and the stator base 1, a plurality of magnetic rings 6 are fixedly connected to the inner wall of the stator base 1, a rotor assembly is arranged inside the stator base 1, and the rotor assembly is used to drive the motor.

[0024] Specifically, first, the magnetic ring 1 6 inside the stator frame 1 and the magnetic ring 2 9 inside the rotor main shaft 7 are used to utilize magnetic adsorption and then magnetic positioning to ensure the alignment and fixation of the stator and the rotor. This method not only avoids the thermal stress and material deformation that may be introduced by traditional riveting, but also simplifies the assembly process and improves the reliability of the motor. The stator winding 3 effectively reduces hysteresis and magnetic loss, thereby improving the efficiency and energy conversion efficiency of the motor. The optimized design of the stator core 2 ensures the uniform distribution of the magnetic field, further improving the performance of the motor. In addition, the heat dissipation holes 4 and the heat dissipation channels 5 help to remove heat in time under high load conditions, maintain the temperature stability of the motor, and extend the service life and reliability of the motor. This comprehensive design takes into account the mechanical structure, electromagnetic properties and thermal management, ensuring the efficient operation and reliability of the motor under various working conditions, so that the motor not only achieves an excellent level in performance and efficiency, but also is more convenient and reliable during assembly and maintenance.

[0025] Reference Figure 3 The rotor assembly includes a rotor main shaft 7, which is slidably connected to the inside of the stator frame 1.

A bidirectional shaft 11 is fixedly connected to the inside of the rotor main shaft 7, and rotor windings 10 are arranged on both sides of the outer wall of the rotor main shaft 7.

[0026] Specifically, first, the magnetic ring 1 6 inside the stator frame 1 and the rotor core 8 on the outer wall of the rotor main shaft 7 are used to provide a magnetic circuit and support the rotor winding 10. The magnetic ring 2 9 maintains the magnetic positioning between the stator frame 1 to ensure the stability of the structural connection. The rotor winding 10 is a key component, which is responsible for receiving the induced current in the stator and generating a rotating magnetic field. This rotating magnetic field interacts with the magnetic field of the stator winding 3 to generate torque, so that the motor can convert electrical energy or mechanical energy. The connection between the bidirectional shaft 11 and the rotor main shaft 7 provides the rotor's rotation axis, so that the rotor can rotate freely inside or outside the stator. This support ensures the normal operation of the motor or generator. Through the synergy of these designs and components, the motor can efficiently convert energy forms and realize the conversion from electrical energy to mechanical energy or vice versa.

[0027] Working principle: When connecting this stator and rotor structure, firstly, the magnetic ring 1 6 inside the stator frame 1 and the magnetic ring 2 9 inside the rotor main shaft 7 are magnetically adsorbed and then magnetically positioned to ensure the alignment and fixation of the stator and the rotor. This method not only avoids the thermal stress and material deformation that may be introduced by traditional riveting, but also simplifies the assembly process and improves the reliability of the motor. The stator winding 3 reduces hysteresis and magnetic loss, the stator core 2 optimizes the magnetic field distribution and motor efficiency, the heat dissipation holes 4 and the heat dissipation channels 5 ensure that the temperature stability and long-term reliability of the motor are maintained under high load conditions, the rotor core 8 on the outer wall of the rotor main shaft 7 is used to provide a magnetic circuit and support the rotor winding 10, the magnetic ring 2 9 maintains magnetic positioning with the stator frame 1 to ensure the stability of the structural connection, the rotor winding 10 is used to receive the induced current in the stator and generate a rotating magnetic field, and the connection between the bidirectional shaft 11 and the rotor main shaft 7 provides the rotation axis of the rotor, so that the rotor can rotate freely inside or outside the stator.
