PROBLEM TO BE SOLVED: To provide a buried-type magnetic motor capable of providing reduction in torque ripple and restraining degradation in torque. SOLUTION: This buried-type magnetic motor has a stator 2 in which a winding is wound around a plurality of teeth 7 formed in a roughly cylindrical condition and formed so as to be extended toward an axis center at a an equal angle interval in a circumferential direction, and a rotor 3 formed by accommodating a plurality of V-shaped permanent magnets 12, 13 disposed in a roughly V shape at an inner side in a diametrical direction in a protruded condition in an inner portion of the rotor core 11 in a roughly column shape in a circumferential direction and accommodated in an inner side of the stator 2 so as to be rotated freely. Magnetic circuit forming portions 31-36 which extend in a diametrical direction between the respective V-shaped permanent magnets 12, 13 are formed at the rotor core 11. Besides, anglesθ1,θ2 on the inner side forming V of the V-shaped permanent magnets 12, 13 which are adjacent to each other in the diametrical direction are set so as to be different. The respective centers in the circumferential direction and the center in the circumferential direction of the teeth 7 in the adjacent magnetic circuit forming portions are set so as not to synchronously become in a series condition in the peripheral direction respectively.
