  • Eddy-current actuated balancer for rotating machinery
    Patent number: 8281686
    Abstract: An eddy-current actuated balancer includes a barrel having a locating wall at one end thereof; two balancing wheels mounted around the barrel and carrying a respective counterweight at the border, a washer set between the balancing wheels, an elastic ring and a lock ring and a pulsed magnetic field generator mounted on each balancing wheel. The balancing wheels, the washer and the elastic ring are clamped between the locating wall of the barrel and the lock ring. Each pulsed magnetic field generator is controlled to generate a pulsed magnetic field acting upon the associating balancing wheel during its rotation for inducing an eddy current that causes the associating balancing wheel to make an angular displacement relative to the barrel for balance adjustment.
