PROBLEM TO BE SOLVED: To provide a manufacturing method of a motor by which shaft displacement of a rotor can be suppressed while suppressing deformation of an end frame.SOLUTION: Each of frames to be disposed at both sides of a stator core 15 in an axial direction includes a planar core holding surface that is orthogonal with an axial line of a rotation axis of a rotor, and a planar pressurized surface that is in parallel with the core holding surface. A core pressurizing jig 60 is abutted to frame abutment parts 15d and 15e to which the core holding surface is abutted, on both end faces of the stator core 15 in the axial direction, and the stator core 15 is pressurized in the axial direction by the core pressurizing jig 60. Next, the core holding surface is abutted to the frame abutment parts 15d and 15e and the frame is disposed at both sides of the stator core 15 in the axial direction. The frame is then pressurized closer to the stator core 15 by a pressurizing jig including a first pressurizing surface that is abutted to the pressurized surface of one frame, and a second pressurizing surface that is in parallel with the first pressurizing surface and abutted to the pressurized surface of the other frame. In the middle of the pressurization step, the pair of frames are coupled with each other.SELECTED DRAWING: Figure 8 |
