Abstract
The embodiments described herein include a method and system for determining velocity and a motor controller implementing such velocity determination. In one embodiment, a rotatable element has a digital encoder coupled thereto for determining discrete angular positions of the rotatable element. An amount of time for the rotatable element to rotate between two successive ones of the discrete angular positions is measured. The amount of time is converted to a rotational velocity determination of the rotatable element.
