  "textContent": "The motor is provided with: a rotor core; permanent magnets disposed on the outer circumferential surface of the rotor core and magnetized in parallel orientation; and a salient pole saliently formed between the permanent magnets. The ratio of the number of magnetic poles of the permanent magnets to the number of teeth is 2:3. Sloped surfaces are formed on the side surfaces of the permanent magnets in the circumferential direction. The angle θ between lines L and lines L is an electrical angle of 13° or more, said lines L connecting outer circumferential corner portions where the sloped surfaces and the outer circumferential surface are connected to each other and the shaft center, said lines L connecting the radial direction outermost side of the circumferential side surface of the salient pole and the shaft center.",
