Question

This is electromechanical energy conversion ..single excited system

N turns The figure illustrates a magnetic yoke with infinite permeability; and an air gap with magnetic permeability 4, length g, and cross-sectional area Dw. An incompressible block with length />> D, magnetic permeability u and cross-sectional area wg can move in the x direction as shown. Both the magnetic block and the yoke can be assumed to have negligible electrical conductivity. There is an N turn winding around the magnetic yoke driven by a DC current source lo. Assume throughout that the position x of the moveable block is bounded as 0<x<D. (a) Find the flux linkage (2)-current (i) relationship for the winding in terms of x, µ uo. N and the dimensions of the magnetic circuit. (b) If the magnetic block is forced to move with a displacement given by x = xo +xcosar, find the voltage developed across the current source.
