Abstract
Disclosed is a method and apparatus for determining the dynamic characteristics of a desired component of an actuator assembly. Further, said method and apparatus are capable of determining the dynamic characteristics independent of any drive servo electronics. The system and method can also be used to determine other operating parameters such as rotational inertia. This information is useful for design verification, quality assurance and failure analysis.
