Electric machine with coaxial shafts and guiding assembly
The patent US12034342B2 describes an innovative electric machine featuring a unique shaft assembly that includes a first shaft and a second shaft arranged coaxially. The design incorporates a bearing positioned between the two shafts, facilitating the connection of a first rotatable body to the first shaft and a second rotatable body to the second shaft. The first rotatable body can function as either a stator or rotor, while the second rotatable body serves the opposite role. A guiding assembly is integrated to restrict the movement of the first rotatable body relative to the first shaft, ensuring stability in both circumferential and radial directions.
Further claims detail the structural components of the guiding assembly, which includes various inserting and socketing portions designed for precise engagement. The assembly features guiding ribs and grooves that enhance the fit between the tubular structural portion and the first shaft. Additionally, the design incorporates flanges for secure connections and allows for the integration of magnetic pole modules within the rotor bracket. The patent also outlines an assembling method for the electric machine, emphasizing the sequential arrangement of the shafts and rotatable bodies to achieve the desired configuration. This comprehensive design aims to improve the efficiency and functionality of electric machines, potentially advancing applications in various industries.
