Abstract

A system for damping audible noise from a drive train. One embodiment is a system with an audible noise signal from a drive train wherein a damping circuit produces a damping torque that is a phase shifted and amplified version of the noise signal that is applied to the air-gap torque of a generator or motor coupled to the drive train and effectively reduces the audible noise.
