[0002] In the field of motor technology, the stator, as one of the core components of a motor, directly affects the motor's operating efficiency and stability through its structure and performance. With the continuous development of industrial technology and the increasing awareness of energy conservation, the requirements for motor stators are becoming increasingly stringent. The dual-winding switching energy-saving motor stator structure has emerged to address this need. Through its unique winding design and switching mechanism, it achieves efficient operation and energy savings under various working conditions. This stator structure not only improves the motor's flexibility and adaptability but also meets the urgent needs of modern industry for high-efficiency, energy-saving motors.

[0003] However, traditional motor stator technology has some obvious drawbacks. On the one hand, the winding structure of traditional stators is simple and cannot be flexibly adjusted according to changes in operating conditions, resulting in low efficiency and serious energy waste under partial load or special operating conditions. On the other hand, the installation and positioning methods of traditional stators are relatively complex, increasing the manufacturing and assembly costs of the motor and also affecting its operational reliability. These shortcomings not only limit the application scope of motor technology but also impose unnecessary burdens on the environment and energy. Therefore, developing a simple and efficient energy-saving motor stator structure with dual winding switching function is of great significance for promoting the development of motor technology and achieving energy conservation. To this end, we propose a dual-winding switching energy-saving motor stator structure. Utility Model Content

[0024] Furthermore, the output end of the inlet 2 is wound with a winding 6, and the output end of the second inlet 3 is wound with a second winding 7.

[0036] 8. Winding 6: Winded around the output end of inlet 2, it is an important part of the motor operation;

[0037] 9. Second winding 7: Winded around the output end of the second inlet 3, together with winding 6, it forms a double winding structure, improving the flexibility and adaptability of the motor.

[0038] 10, 8, 9, 10, 11, 12, 13: These form a complex winding connection network, providing more possibilities for the external control and adjustment of the motor.

[0039] 11. Positioning groove 14: It is formed on one side of the outer wall of stator slice 1, and the cross section is semi-circular, which facilitates the accurate positioning and installation of the stator in the motor.

[0040] Working Principle: First, the stator slice 1 is designed with two sets of opposing fan-shaped, equidistant wire inlets 2 at its top, with ten inlets in each set. This layout provides a foundation for the uniform winding of the winding 6. Simultaneously, near the top of the wire inlets 2, the stator slice 1 also has two sets of opposing fan-shaped, equidistant second wire inlets 3, with two inlets in each set, located between the two sets of wire inlets 2. This design creates a circular stator slot between the wire inlets 2 and the second wire inlets 3, providing an optimized spatial structure for winding installation and the distribution of the motor's magnetic field. Then, the vertical stacking of multiple sets of stator slices 1 forms the stator laminated core, enhancing the overall strength and stability of the stator. Fixing bolts 5, inserted into both ends of the inner wall of the shaft hole 4, firmly connect the stator laminated core together, ensuring the stability and reliability of the motor during operation. Regarding the winding layout, the output end of the wire inlet 2 is wound with the winding 6, while the output end of the second wire inlet 3 is wound with the second winding 7. This dual-winding configuration provides greater flexibility and controllability for motor operation. The leads 8 and 9 extending from one end of the second winding 7, along with the third and fourth leads 10 and 11 located away from the lead ends, form a complex winding connection network. This allows the motor to switch and adjust the windings according to different operating requirements, thereby achieving energy savings. Furthermore, the fifth lead 12 extending from one end of lead 8 and the sixth lead 13 located away from the fifth lead end facilitate external connections and control of the motor. The positioning groove 14, with a semi-circular cross-section, is located on one side of the outer wall of the stator slice 1. This design aids in the accurate positioning and installation of the stator within the motor.
