Abstract

To suppress rotor vibration due to imbalance

an active online electromagnetic balancing device is developed. The magnetic-field distribution and electromagnetic force generated by the device are analyzed via finite-element modeling by using the commercial software ANSYS. Based on the dynamic finite-element model of a rotor

the relationship matrix between unbalanced response and imbalance is reduced to identify the equivalent concentrated imbalance. This electromagnetic balancing device is verified experimentally. The results show that the electromagnetic force from the electromagnetic balancing device effectively suppresses the vibration due to imbalance. This kind of electromagnetic dynamic balancing device is especially suitable for high-speed and high precision online balancing.
