<P>PROBLEM TO BE SOLVED: To provide a motor for disk rotation which can be manufactured by using a simple method and a disk drive including the motor for disk rotation. <P>SOLUTION: A motor 100 as a motor for disk rotation includes: a shaft 13; a bearing 30 located on the outer diameter side of the shaft 13 and rotatably supporting the shaft 13; and a stator 20 fixing the bearing 30. The stator 20 includes: a stator core 21 mounted to the outer peripheral face of the bearing 30; a stator coil 22 wound around the stator core 21; and an insulator 26 insulating the stator core 21 and the stator coil 22 mutually. The shaft 13 includes a groove 13a formed on the outer peripheral face of the shaft 13. The insulator 26 includes a coming-off prevention washer 26a engaged with the groove 13a, and the coming-off prevention washer 26a is formed at an end on the inner diameter side of the insulator 26. <P>COPYRIGHT: (C)2013,JPO&INPIT |
