Abstract

The invention relates to the technical field of stepping motor assembling and particularly relates to a method for assembling a high and low temperature vacuum stepping motor. The method comprises steps that a rotation shaft and a core are assembled; an upper bearing and a lower bearing are simultaneously assembled with the rotation shaft; a stator is assembled with a motor casing. The method is advantaged in that under the condition that a rotor and the stator assembly are assembled at the same device, assembling accuracy requirements are satisfied, moreover, in the rotor assembling process,a problem that a magnetic steel near a center through hole on the core is uneven in force bearing due to overproof coaxiality among the upper bearing, the core, the rotation shaft and the lower bearing is avoided, a problem of avulsion due to overlarge regional impact is avoided, and in the assembling process of the stator assembly, a problem of damage to the stator or the motor casing caused by the overlarge regional impact due to uneven force borne by the stator or the motor casing is avoided.
