Abstract
Improved circular force generator devices (100), systems, and methods for use in an active vibration control system are disclosed. The present subject matter can include improved rotary actuator devices, systems, and methods in which a center shaft (120) is positioned in a fixed relationship with respect to a component housing (114). At least one movable body can be positioned in the component housing and rotatably coupled to the center shaft by a radial bearing (130), the at least one movable body comprising a motor (110) and at least one eccentric mass (150). With this configuration, the motor can be configured to cause rotation of the movable body about the center shaft to produce a rotating force with a controllable rotating force magnitude and a controllable rotating force phase.
