ASSEMBLY METHOD AND FIXING DEVICE FOR ELECTRIC MOTOR

The present application relates to an assembly method and a fixing device for an electric motor. The assembly method for the electric motor comprises the steps: 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, wherein at least two segment modules in the circumferential direction are assembled into the complete stator and rotor, and then a main shaft is coaxially assembled with the stator and the rotor as a whole; and carrying out dismounting, and dismounting the fixing devices.
