摘要： PROBLEM TO BE SOLVED: To provide a motor which is resistive to high-speed rotation and assures higher efficiency by reducing torque ripples. SOLUTION: In a motor comprising a rotor 2 and a stator 103 provided to cover the rotor, the rotor 2 includes a plurality of permanent magnets 6 to form a permanent magnet group 9 providing a plurality of permanent magnets 6 for each pole. Each permanent magnet 6 is allocated with each other via a partition wall 8 keeping an interval. The permanent magnet group 9 is formed as a whole in a sine-wave shape as the basic waveform of the rotary magnetic field. With such a structure, magnetic flux destination distribution in the gap between the rotor 2 and stator 103 is approximated by the sine-wave, and a torque ripple is reduced to assure efficiency. Moreover, the partition wall 8 increases strength in the diameter direction of the rotor 2, and the rotor 2 is resistive to the centrifugal force of the high-speed rotation.
