Title:
ROTOR CORE, ROTOR, AND ROTATING ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/171530
Kind Code:
A1
Abstract:
This rotor core can rotate about a central axis and comprises: a plurality of magnetic pole parts disposed at intervals in the circumferential direction; and a plurality of magnetic pole intermediate parts respectively positioned between the magnetic pole parts adjacent in the circumferential direction. Each of the plurality of magnetic pole intermediate parts has a through-hole group including a plurality of through-holes disposed at intervals in a radial direction. Each through-hole has an outer end positioned on the radial-direction outer edge of the rotor core, and the outer ends are respectively disposed on the plurality of magnetic pole intermediate parts in a first region and a second region disposed sandwiching the circumferential-direction center of the magnetic pole intermediate parts. The number of outer ends disposed in the second region is less than the number of outer ends disposed in the first region.
