PURPOSE:To provide the assembly method, of an electric motor, wherein a stator and a rotor can be assembled easily. CONSTITUTION:A rotor 7 is arranged in a state that its shaft 9 is directed to the vertically upper part. A stator 4 in which a laminated core 3 has been fixed and bonded to the outer circumference at the tip part of a boss part 2a at a stator frame 2 is arranged at the upper part of the rotor 7 in a state that the tip of the boss part 2a is directed to the lower part. A process wherein bearings 8, 10 are gap-fitted at the inner side of the boss part 2a in the stator and the shaft 9 is fitted to the inner side of the bearings 8, 9 while the fall of the bearing 10 situated at the lower side is being suppressed by a stopper part 12 installed at the inner circumferential part of the laminated core 3 is performed. |
