Abstract: An assembly method and a fixing device for an electric motor are provided. The assembly method includes: carrying out preparation, wherein a stator of the electric motor is segmented, in the circumferential direction, into at least two stator segments, and a rotor of the electric motor is segmented, in the circumferential direction, into at least two rotor segments; carrying out pre-assembly, wherein the stator segments and the rotor segments are coaxially fixed to fixing devices to form segment modules, and predetermined gaps are maintained radially between the stator segments and the rotor segments; carrying out adjustment, wherein at least two fixing devices are moved and adjusted such that the stator segment and the rotor segment of the adjacent segment modules are mutually attached and aligned with each other along segmental end faces in the circumferential direction; carrying out assembly; and carrying out dismounting, and dismounting the fixing devices.

Abstract: The present application relates to an electric machine splitting or assembling method, an electric machine assembling method, and an electric machine splitting or assembling device including a sleeving device separating or coaxially sleeving first and second rotary bodies; the first disassembly device fixes the first rotary body and includes at least two first separable portions, and the first rotary body is split into petals in a circumferential direction by disassembling the first separable portions, or its respective petal segments are assembled in the circumferential direction by combining the first separable portions; and the second disassembly device is fixed to the second rotary body and includes at least two second separable portions, and the second rotary body is split into petals in the circumferential direction by disassembling the second separable portions, or its respective petal segments are assembled in the circumferential direction by combining the second separable portions.
