PROBLEM TO BE SOLVED: To enlarge the main density, and besides, to reduce the noise, in a permanent magnet rotating machine where permanent magnets are arranged in circular form inside the iron core of a rotor. SOLUTION: This is a permanent magnet rotating motor which has a rotor 3 having permanent magnets 6 arranged in circular form within a rotor iron core 7 and a stator 2 having stator winding 5 wound on a salient pole 42 constituted of one part of a stator iron core 4, and in which the air gap between the rotor iron core 7 between the poles of the permanent magnet 6 and the stator iron core 4 is larger than the air gap between the rotor iron core 7 at the center of the pole of the permanent magnet 6 and the stator iron core 4.
