Description

TECHNICAL FIELD The present application relates to a multi-drive magnetic rotating machine. BACKGROUND Traditional magnetic rotating machines usually adopt an integrated rotor structure, in which the permanent magnets (magnetic poles) are embedded or bonded on the rotor core in a fixed manner, and interact with the magnetic field generated by the stator winding to realize rotation. Once the structure is manufactured, the number and size of the magnetic poles and the power level of the machine are fixed, lacking flexibility. In actual applications, when the output power or torque characteristics of the machine need to be adjusted, the entire machine often needs to be replaced, which not only increases the cost, but also reduces the adaptability of the application. In view of this, we propose a new magnetic rotating machine scheme to improve the flexibility of use. SUMMARY To solve at least one of the above problems, the present application proposes a new structure scheme, which adopts the following technical scheme: A multi-drive magnetic rotating machine, comprising a rotor, a coil assembly, and a machine shell. The rotor comprises a shaft core, magnetic poles, and a ring sleeve. The outer side of the ring sleeve is provided with a plurality of insertion slots, and the magnetic poles are fixedly connected to the insertion slots to form an integral whole, and the polarities of adjacent magnetic poles are opposite. The ring sleeve has a shaft hole, and the inner side of the ring sleeve is provided with an elastic clamping column which is movably and elastically extended into the shaft hole. The shaft core is provided with a plurality of blind holes, and the shaft core penetrates into the shaft hole to push the elastic clamping column to retract into the ring sleeve. When the ring sleeve moves to the position of the blind hole, the elastic clamping column is elastically extended to connect with the blind hole, so as to fix the position of the ring sleeve and the magnetic poles. The machine shell is provided with a plurality of coil assemblies. The energized coil assembly cooperates with the magnetic poles on the ring sleeve to drive the rotor to rotate.

[0004] Preferably, a plurality of cavities are arranged on the inner side of the ring sleeve, and the length of the cavity is less than the thickness of the ring sleeve.

[0005] Preferably, a spring is arranged in the cavity, one end of the spring is fixed in the cavity, and the other end is fixedly connected to the elastic clamping column to cooperate with the elastic clamping column to extend and retract.

[0006] Preferably, the length of the elastic clamping column is less than the depth of the cavity.

[0007] Preferably, the end of the elastic clamping column extending into the shaft hole is arc-shaped.

[0008] Preferably, the coil assemblies of each group are independently connected.

[0009] The present application has the following advantages compared with the background art: This solution modularizes the magnetic poles and ring sleeves into interference-fit magnetic pole units, and combines this with a flexible snap-fit ​​structure formed by blind holes on the shaft core and elastic locking posts on the inner side of the ring sleeve, achieving rapid and stable assembly of the magnetic pole units. Simultaneously, multiple independently powered coil assemblies are installed within the housing, allowing the motor to adjust its output power as needed by selecting different sized magnetic pole units or energizing different numbers of coils. The overall structure combines modularity, ease of assembly, and functional expandability, effectively improving the motor's applicability and application flexibility. It boasts advantages such as simple structure, compact fit, and rational design; therefore, it is a product with superior technical and economic performance.
