Abstract

A rotating electrical machine (10) includes a rotor (20) that includes: a rotor core (21); and a plurality of permanent magnets (40) forming a magnetic pole (22). Each permanent magnet (40) has an arc shape that is convex toward an inner peripheral side of the rotor core (21), and has: a first arc surface (41) and a second arc surface (42) located on an outer peripheral side and the inner peripheral side of the rotor core (21), respectively. The permanent magnets (40) form two or more layers (S1-S3) that are arranged in a radially inward direction of the rotor core (21). The number of permanent magnets (40) per layer (S1-S3) increases by one in the radially inward direction. The permanent magnets (40) have the same shape. A distance (L1, L2) between the layers (S1-S3) adjacent to each other is smaller on the outer peripheral side than at a position distant from an outer periphery of the rotor core (21) along a circumferential width direction of each permanent magnet (40).
