Abstract
A permanent magnet type rotating electric machine includes a stator, a rotor core, and permanent magnets embedded in the rotor core. The permanent magnets include N-pole magnets, having N-poles opposed to the stator, and S-pole magnets, having S-poles opposed to the stator. The N-pole magnets are arranged adjacent to each other, and the S-pole magnets are arranged adjacent to each other. The outer circumferential portion of the rotor core includes a first N-pole corresponding section corresponding to an N-pole magnet that is not adjacent to an S-pole magnet and is partially wider in the radial direction than a second N-pole corresponding section that corresponds to an N-pole magnet that is adjacent to one of the S-pole magnets.
