PROBLEM TO BE SOLVED: To obtain a motor having high reliability at low vibration and low noise by solving a thrust rigidity. SOLUTION: At the tip of a shaft 1, the securing side magnetic thrust magnet 11 of the first means of a magnetic thrust bearing, and a rotation side magnetic thrust magnet 12 magnetized in the attraction direction on the outer periphery of the securing side magnetic thrust magnet 11, are arranged, and attracted with an attraction force F1. The second means of the magnetic thrust bearing is configured with an attraction force F2 with a rotor magnet 7 and a substrate 4 which is made of an iron. COPYRIGHT: (C)2006,JPO&NCIPI
