Energy-efficient actuator system

摘要

What is described is an actuator system (2) comprising at least one actuator (29, 29′) and an associated control system (8) which is designed for at least two operating modes, at least one of which may be deactivated, whereby one of the operating modes is a high efficiency operating mode.

1. A magnetic bearing actuator system comprising:
at least one electromagnetic actuator configured to generate forces to resist loads within a structure; and at least one control system in communication with the at least one electromagnetic actuator, the at least one control system having at least two operating modes; where at least one mode is a deactivatable high-power operating mode and at least one mode is a high-efficiency operating mode; where the high-efficiency operating mode is activated during normal operation of the magnetic bearing actuator system; and where the control system is configured to detect the loads within the structure and selectively activate the high-power operating mode to avoid impermissible displacement of the structure.
