Title:
回転電機の回転子
Document Type and Number:
Japanese Patent JP6989458
Kind Code:
B2
Abstract:
According to one embodiment, a first permanent magnet and a second permanent magnet are disposed in each magnetic pole of a rotor core. When angular coordinates of intersections of a flux line in a d-axial direction passing an outer end A1 of the first permanent magnet, a flux line in the d-axial direction passing through an inner end A2 of the first permanent magnet, a flux line in the d-axial direction passing an outer end B1 of the second permanent magnet, a flux line in the d-axial direction passing an inner end B2 of the second permanent magnet and a circumscribing circle of the rotor core are respectively defined as θdA1, θdA2, θdB1 and θdB2, the θdA1, θdA2, θdB1 and θdB2 satisfy a formula (−34/p<(θdB1-θdA1)<22/p, −34/p<(θdB2−θdA2)<22/p).
