IMPROVED CIRCULAR FORCE GENERATOR DEVICES, SYSTEMS, AND METHODS FOR USE IN AN ACTIVE VIBRATION CONTROL SYSTEM

摘要

A circular force generator (CFG) (100) is provided for use in an active vibration control system. The CFG comprises a component housing, and a center shaft (120) positioned in a fixed relationship with respect to the component housing. The CFG further comprises a pair of motors (110) each having a rotor (116) and a fixed stator (112), the stator mounted to endplates (114). A rotating mass (150) is eccentrically connected to each rotor (116) such that rotation of the rotor (116) about the shaft (120) generates a circular force with a rotating force magnitude and a controllable rotating force phase. The rotor (116) of each motor (110) is coupled for rotation about the center shaft (120) by a bearing (130) mounted inside the motor (110).
