Unformatted text preview: geometry. We are interested in evaluating terminal voltage by using (2.1.9); thus we are interested in time variations of flux linkage A. If we assume that the system geometry is fixed, except for one movable part whose position can be described instantaneously by a displacement x with respect to a fixed reference, and we further assume that M is a function of field quantities alone (and therefore a function of current), we can write A = AU, x). (2.1.10) (2.1.11) In this expression we have indicated explicit functional dependence only on those variables (i and x) that may be functions of time. We can now use (2.1.10) in (2.1.9) and expand the time derivative to obtain v = dJ, = 0), di + OA dx . dt oi dt ox dt This expression illustrates some general terminal properties of magnetic APDF Split DEMO : Purchase from www.APDF.com to remove the watermark...
