Abstract:
A rotor of a rotating electric machine includes a rotor core, and a plurality of permanent magnets arranged in a two-layer structure having a first layer and a second layer, in the rotor core. Among the permanent magnets, first and second outermost permanent magnets located closest to each of opposite q-axes of each magnetic pole are located relative to each other, such that a radial position of an end portion on a q-axis side and a radially inner side in the first outermost permanent magnet that belongs to the first layer is spaced by a predetermined radial spacing from and is on a radially outer side of a radial position of an end portion on the q-axis side and a radially outer side in the second outermost permanent magnet that belongs to the second layer.
