Document Type and Number:
Japanese Patent JP6869069
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electromagnetic vibration exciter capable of vibrating a vibration object structure without offsetting excitation current with a simple device configuration.SOLUTION: A vibration exciter 10 includes a first electromagnetic coil 11A and a second electromagnetic coil 11B disposed so that a steam generator 101 is interposed between them. A positive half component WA of excitation current having a prescribed vibration waveform is input into the first electromagnetic coil 11A, and a negative half component WB of the excitation current into the second electromagnetic coil 11B. The steam generator 101 is vibrated by being alternately sucked by electromagnetic force exerted by the first electromagnetic coil 11A and the second electromagnetic coil 11B.SELECTED DRAWING: Figure 2
