Abstract
A method for manufacturing a laminated iron core includes: arranging N heating units in the laminated iron core such that the N heating units are aligned in a circumferential direction of the laminated iron core, where N is a natural number of two or more; and heating N regions of the laminated iron core that face the N heating units with the N heating units. The heating includes switching operation of the N heating units from one to less than N at a time.
Claims9
A method for manufacturing a laminated iron core, the method comprising:
- arranging N heating units in the laminated iron core such that the N heating units are aligned in a circumferential direction of the laminated iron core, where N is a natural number of two or more;
- and
- heating N regions of the laminated iron core that face the N heating units with the N heating units,
- wherein the heating includes switching operation of the N heating units from one to less than N at a time.
A method for manufacturing a laminated iron core, the method comprising:
- arranging M heating units to face an inner peripheral portion or an outer peripheral portion of a laminated iron core, where M is a natural number of one or more;
- heating M regions of the laminated iron core that face the M heating units with the M heating units;
- and
- rotating the laminated iron core or the M heating units around a central axis of the laminated iron core, and heating a region of the laminated iron core other than the M regions with at least one of the M heating units.
A heating device comprising:
- N heating units, where N is a natural number of two or more;
- and
- a control unit,
- wherein the control unit is configured to, in a state where the N heating units are arranged in a laminated iron core in a manner of aligning in a circumferential direction of the laminated iron core, perform a process of heating N regions of the laminated iron core that face the N heating units by switching operation of the N heating units from one to less than N at a time.
