Abstract
A method of operating a motor driving a rotating member includes directing rotation of the rotating member at the motor at an initial speed, determining a first frequency of a first noise component generated by the rotating member at the initial speed, determining a second noise component having a second frequency phase shifted 180° with respect to the first frequency, determining a torque modifier of the motor to generate the second noise component from the motor, and directing activation of the motor according to the determined torque modifier.
