PURPOSE: The torque ripple arranging the permanent magnet of the flat pattern to the rotational symmetry in the permanent magnet buried rotation electromagnetic field is to be controlled. CONSTITUTION: The permanent magnet(15) buried spinning electron instrument the circumference of the respective rotor coping with being formed in a neighboring pair of pole ends into the depressed part, and a neighboring pair of depressed parts falling to the peripheral direction of rotor, and the convex part between a pair of depressed parts locating between the magnetic pole having than each highest deep part of a pair of depressed parts in the outside of the radial direction, and of having in the magnetic pole center side of the permanent magnet having the depressed part, corresponding to one-way is the pole end of one-way than the bridge as to the peripheral direction of rotor of a neighboring pair of pole ends.
