【Abstract】 A new passive electromagnetic damper worked with DC without control is developed.The vibration characteristics of a rotor system with passive electromagnetic damper under different current are studied experimentally.The results show that the resonant vibration of rotor with passive electromagnetic can be damped effectively with the current increase and the damper may be used in industry for its simplicity and reliability.更多还原
