Many applications require a high-dynamic short stroke linear actuator with a low mover inertia; at the same time the mechanical reliability represents a crucial factor for high frequency operation cycles. Under such circumstances, the supply feeding cables and the related cable tray may represent a weak point and a considerable load increase at the same time. The device presented in this paper doesn’t require any cable supply, since the power required by the moving windings is transferred via the electromagnetic coupling with a stator AC supplied primary winding.

Abstract
Many applications require a high-dynamic short stroke linear actuator with a low mover inertia; at the same time the mechanical reliability represents a crucial factor for high frequency operation cycles. Under such circumstances, the supply feeding cables and the related cable tray may represent a weak point and a considerable load increase at the same time. The device presented in this paper doesn’t require any cable supply, since the power required by the moving windings is transferred via the electromagnetic coupling with a stator AC supplied primary winding.File in questo prodotto:
