<P>PROBLEM TO BE SOLVED: To effectively suppress vibration generated when driving a rotating electric machine. <P>SOLUTION: A dynamic vibration absorber 50A includes a leaf spring 54A whose one end is attached to an outer peripheral surface of a motor 100 through a mounting part or directly to a stator, and a weight 56A attached to an upper surface of the other end of the leaf spring 54A. A dynamic vibration absorber 50B is configured in the same manner. The pair of the dynamic vibration absorbers 50A and 50B are disposed with a space corresponding to an interval between an antinode S1 and a node P1 in a vibration mode by the electromagnetic force generated when the rotating electric machine is driven. The vibration of the motor 100 can be suppressed effectively since each of the pair of the dynamic vibration absorbers 50A and 50B performs damping of two mode components whose phases are shifted in a circumferential direction by the interval between the antinode and the node composing the vibration mode respectively even if the vibration mode rotates in a circumferential direction (circumferential direction of the stator 120). <P>COPYRIGHT: (C)2013,JPO&INPIT |
