Title:
モータロータ、過給機、及びモータロータの製造方法
Document Type and Number:
Japanese Patent JP6566139
Kind Code:
B2
Abstract:
A motor rotor is configured to include a tubular inner sleeve, an annular magnet mounted on the outside of the inner sleeve in a radial direction of the inner sleeve, and a ring member disposed on the outside of the magnet in an axial direction of the inner sleeve and mounted on the outside of the inner sleeve in the radial direction of the inner sleeve. A linear expansion coefficient of the inner sleeve is higher than the linear expansion coefficient of the magnet. The ring member is mounted on the inner sleeve by shrinkage-fitting, and a gap is provided between the ring member and the magnet in the axial direction of the inner sleeve.
