Abstract

Mechanical motion in machines is typically achieved through the use of electric motors. In some instances, the speed of the motors is also electronically controlled, for example, DC servomotors and stepper motors. When used in office equipment environments, these motors can frequently be the source of acoustic vibration, giving rise to considerable noise.
