Prоblem 1. (24 pts) Fоr the E-I cоre trаnsformer shown below аnswer the following questions. The components аre assumed to be held fixed (no motion). a. Draw the magnetic equivalent circuit model you would use to model the magnetic behavior of the transformer. Make sure to include the polarity of the sources and the values of reluctances. (6 pts) b. λ1=_i1+_i2λ2=_i1+_i2{"version":"1.1","math":"λ1=_i1+_i2λ2=_i1+_i2"} Fill in the blanks with values. Show all work. (12 pts) c. If i1=10 A{"version":"1.1","math":"i1=10 A"} and i2=10 A{"version":"1.1","math":"i2=10 A"}, determine the energy being stored in the coupling field. (6 pts) Problem 2. (16 pts) For the 2-winding transformer in problem 1: a. Draw a T-equivalent circuit to model the transformer in which the secondary winding is referred to the primary winding (e.g., you will have v2', i2'{"version":"1.1","math":"v2', i2'"} in your circuit). (8 pts) b. If the secondary terminal is connected to a load that is a 0.25 Ω{"version":"1.1","math":"Ω"} resistor, and V1=2*10cos(1000t){"version":"1.1","math":"V1=2*10cos(1000t)"}, determine I2{"version":"1.1","math":"I2"}. State any assumptions made to simplify your analysis. (8 pts) Problem 3. (12 pts) If Express fe(i1, i2, x){"version":"1.1","math":"fe(i1, i2, x)"}. (12 pts) Problem 4. (18 pts) For the stator shown in the figure below, assume the coils are connected in series to form the a-phase winding. a. Plot Bas{"version":"1.1","math":"Bas"} versus ϕsm{"version":"1.1","math":"ϕsm"}. (8 pts) b. If ias=1 A{"version":"1.1","math":"ias=1 A"}, determine the portion of the a-phase winding flux linkage attributed to the as1 coil. (10 pts) Congratulations, you are almost done with this exam. .
