A permanent magnet rotating electrical machine includes a rotor which has permanent magnets buried in a plurality of permanent magnet insertion slots that are provided in a rotor core, and the rotor is rotatably supported by a rotary shaft with a gap on the inner peripheral side of a stator. When the axis of magnetic flux for the permanent magnet is set as a d-axis and the position deviated from the d-axis by electrical angle of 90° is set as a q-axis, the permanent magnet insertion slot is located on the q-axis and a first permanent magnet magnetized in the direction orthogonal to the q-axis is buried in the permanent magnet insertion slot. The permanent magnet insertion slot is located on the d-axis and a second permanent magnet magnetized in the direction parallel to the d-axis is buried in the permanent magnet insertion slot, while at least one or more third permanent magnets buried in the permanent magnet insertion slots are provided between the first permanent magnet and the second permanent magnet. Thereby, the environmental load discharged from a motor vehicle is reduced.
