Abstract
A method of manufacturing a rotor includes mounting a plurality of core members to a shaft in a state by inserting the shaft into a shaft hole that penetrates through the plurality of core members in a height direction. An inner diameter of the shaft hole is larger than an outer diameter of the shaft. The method includes pressing the plurality of stacked core members together in the height direction to form a stack in which the plurality of core members are located adjacent to each other, and the shaft hole is engaged with the shaft.
Claims19
A method of manufacturing a rotor, the method comprising:
- mounting a plurality of core members to a shaft in a state where the shaft is inserted into a shaft hole of each of the plurality of core members along an extending direction of the shaft hole and where each of the plurality of core members is oblique to the shaft, the shaft hole penetrating through each of the plurality of core members in a height direction thereof and obliquely extending in the height direction, an inner diameter of the shaft hole being larger than an outer diameter of the shaft;
- and
- pressing the plurality of stacked core members together in the height direction to form a stack in which the plurality of core members are located adjacent to each other and the shaft hole is engaged with the shaft so that an inner peripheral edge of the shaft hole of each of the plurality of core members bites into the shaft by the pressing to align the shaft hole of each of the plurality of the core members, change an attitude of the shaft hole and give the shaft hole of the stack as a whole a non-linear shape.
