Vibrational drive has eddy current braking system consisting of one or more permanent magnets and electrical conductor installed between movable unbalanced mass and end plate of electric drive

摘要

The vibrational drive has unbalanced masses adjustable dependent upon direction of rotation and which consist of a movable unbalanced mass (3) and a fixed unbalanced mass (4) mounted on the drive shaft of an electric drive. An eddy current braking system, consisting of one or more permanent magnets (5) and an electrical conductor, preferably an aluminum ring (6), is installed between the movable unbalanced mass and the end plate (7) of the electric drive (2).
