Abstract
Outer circumference of a rotor is alternately provided with a plurality of circumferential portions and a plurality of convex portions. Straight lines each connecting a rotational axis to one of circumferential centers of circumferential portions are referred to as radial lines. Straight lines each bisecting one of convex portions are referred to as bisectors. A plurality of magnetic flux blocking regions are located on a rotor. One of the magnetic flux blocking region is located in a range between the radial line and the bisector adjacent to and preceding the radial line in the rotation direction. Therefore, a permanent magnet embedment rotating electric machine is capable of preventing decreases in torque and suppressing torque ripple.
