Document Type and Number:
Japanese Patent JP7317856
Kind Code:
B2
Abstract:
In an IPM rotor, a first core sheet has a first sheet hole forming a part of an accommodation hole. The first sheet hole has an edge portion having a flat spring portion which is bent by a magnet through insertion of the magnet into the accommodation hole. A pair of recesses forming a clearance with respect to the magnet are formed at both side portions of the flat spring portion of the edge portion of the first sheet hole. A size of the clearance is set based on a relationship between a magnitude of a pressing force of the flat spring portion on the magnet and variation in pressing force.
