Title:
MOTOR MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/113404
Kind Code:
A1
Abstract:
This motor manufacturing method comprises a step of preparing parts of an axial gap motor and a step of assembling the parts. The parts include: a rotor; a stator; a shaft that is the rotational axis of the rotor; a bearing for rotatably supporting the shaft; a case having a first plane on which the stator and the bearing are placed; and a shim disposed between the first plane and the bearing or between the first plane and the stator. The step of preparing the parts has: a step of obtaining a predicted length of the gap between the rotor and the stator in consideration of the actual dimension of the stator; and a step of determining the thickness of the shim on the basis of the difference between the design length of the gap and the predicted length thereof.
