发明名称 Outside rotor electric machine with reduced air gap variation
摘要 A method of providing an outside rotor electric machine having a reduced radial air gap variation across an axial length of the air gap, the machine including a rotor having a cylindrical elongated portion supporting magnets and a flange extending at least partially radially from a rotating shaft, the method comprising increasing a radial deflection of the elongated portion in proximity of the flange by connecting the elongated portion to the flange through a radial spring having a stiffness lower than that of the elongated portion.
