The utility model discloses a (combined) structure for assembling an electric main shaft rotor, and the structure comprises a shaft 1, a front end cover 2, an engine seat 3, a common A-type key 4, a rotor lining 5, a stator core 6, a rotor 7, a Z1-type expanding sleeve 8, an expanding sleeve gland 9, and a rear end cover 10. The interior of the stator core is provided with a temperature sensor. When the internal temperature of a motor exceeds a preset threshold value, the temperature sensor gives an alarm. The structure provided by the utility model irons out the defects that a conventional structure for assembling the electric main shaft rotor is difficult to maintain, is large in number of working processes and is higher in maintenance cost. The structure is simple in process, is stable and reliable in operation, and is simpler and more convenient in maintenance.
