PROBLEM TO BE SOLVED: To provide a rotor structure of an embedded magnet-type synchronous motor having a simple structure and capable of increasing torque generated by the same amount of input current, while suppressing an increase in manufacturing cost.SOLUTION: A rotor structure of a rotary electric machine 1 arranged inside a stator 5 is provided with: rectangular slots 7b formed such that a direction orthogonal to the rotor axial direction and the rotor radial direction may be the longitudinal direction; and seven neodymium magnets 9 disposed in series in the longitudinal direction in the respective slots 7b. The magnetization direction of a central neodymium magnet 9b is set to a direction orthogonal to the rotor axial direction and the longitudinal direction. Meanwhile, the magnetization direction of both-end neodymium magnets 9a is set to a direction inclined to the inner side in the longitudinal direction of each slot 7b by a predetermined angle from the direction orthogonal to the rotor axial direction and the longitudinal direction. |
