Problem 2- Lateral Reluctance Actuator 20 ptsl The actuator shown below has a core and movable section of steel. The moveable section is supported by bearings with permeability u o, with Hr. All parts of the actuator extend a depth a into the page The rest of the parameters for the actuator N-150 a-5 cm a x a cross section b- 25 cm g 2 cm K-40 Nm Equilibrium position of the steel, xi = 4 cm Spring Constant depth a into page N tuns Neglect fringing around the air-gaps and mechanical losses. Assume that the moveable section is long enough so that the narrower section of the core always provides an area of a nomal to the a) Draw the magnetic equivalent circuit of the above actuator. Neglect the reluctances of the b) Calculate the equivalent reluctances, based on the equivalent circuit in part(a), as function c) From part(b), calculate the total inductances L(x) as a function of displacement x, for (1) flux flow core in your equivalent circuit. ofx for both (1) positive and (2) negativex positive and (2) negative x. d) Calculate the current required to hold the steel section at a displacement of x = 2 cm.
