A motor comprising: a stator which comprises an annular stator core and a plurality of teeth projecting inward from an inner circumferential surface of the stator core in a radial direction; coils which are wound around the teeth; a shaft which rotates on an inner side of the stator core in the radial direction; a rotor core which is affixed to the shaft with a rotation axis of the shaft as a center in the radial direction; a plurality of permanent magnets which are disposed on an outer circumferential surface of the rotor core and magnetized in parallel orientation; and a salient pole which is formed to project outward in the radial direction between the permanent magnets adjacent to each other in a circumferential direction of the outer circumferential surface of the rotor core and with which circumferential side surfaces of the permanent magnets are brought into contact, wherein a ratio of the number of magnetic poles of the permanent magnets to the number of the teeth is 2:3, characterized in that: inclined surfaces are formed on the circumferential side surfaces of the permanent magnets to gradually separate from the salient pole from a radial-direction outer end of a salient pole contact surface toward an outer circumferential surface of the permanent magnets on an outer side in the radial direction, wherein for each permanent magnet, the inclined surfaces are parallel to a line connecting a circumferential center of the permanent magnet and the rotation axis, and an angle (θ2) between a line, which connects the rotation axis and a corner portion formed at where one of the inclined surfaces and the outer circumferential surface of the permanent magnet are connected to each other, and a line, which connects the rotation axis and a radial direction corner portion of the salient pole that is adjacent to the corner portion of the permanent magnet and is located at an outermost side in the radial direction of a circumferential side surface of the salient pole, is an electrical angle of 13° or more. a stator which comprises an annular stator core and a plurality of teeth projecting inward from an inner circumferential surface of the stator core in a radial direction; coils which are wound around the teeth; a shaft which rotates on an inner side of the stator core in the radial direction; a rotor core which is affixed to the shaft with a rotation axis of the shaft as a center in the radial direction; a plurality of permanent magnets which are disposed on an outer circumferential surface of the rotor core and magnetized in parallel orientation; and a salient pole which is formed to project outward in the radial direction between the permanent magnets adjacent to each other in a circumferential direction of the outer circumferential surface of the rotor core and with which circumferential side surfaces of the permanent magnets are brought into contact, wherein a ratio of the number of magnetic poles of the permanent magnets to the number of the teeth is 2:3, characterized in that: inclined surfaces are formed on the circumferential side surfaces of the permanent magnets to gradually separate from the salient pole from a radial-direction outer end of a salient pole contact surface toward an outer circumferential surface of the permanent magnets on an outer side in the radial direction, wherein for each permanent magnet, the inclined surfaces are parallel to a line connecting a circumferential center of the permanent magnet and the rotation axis, and an angle (θ2) between a line, which connects the rotation axis and a corner portion formed at where one of the inclined surfaces and the outer circumferential surface of the permanent magnet are connected to each other, and a line, which connects the rotation axis and a radial direction corner portion of the salient pole that is adjacent to the corner portion of the permanent magnet and is located at an outermost side in the radial direction of a circumferential side surface of the salient pole, is an electrical angle of 13° or more.
