Title:
ELECTROMECHANICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/042278
Kind Code:
A3
Abstract:
An electromechanical device, comprising: a first member and a second member arranged to move relative to the first member and comprising first and second retardation portions; wherein the first member is arranged to generate a movable magnetic field and wherein the relative speed at which the magnetic field moves relative to the second member is adjustable, wherein at a first relative speed the interaction of the magnetic field with the second member results in the first retardation portion generating an electrical current and a retardation force opposing the movement of the second member being applied to the first retardation portion; and wherein at a second relative speed, different from the first relative speed, the interaction of the magnetic field with the second member results in a) the amount of current generated by the first retardation portion being less than the amount of current generated by the first retardation portion at the first relative speed and b) an amount of retardation force opposing the movement of the second member being applied to the second retardation portion, which is greater than an amount of retardation force applied to the second retardation portion at the first relative speed.
