Unformatted text preview: Special problem #2 (partial answer 16 Joules, 32 Joules, -800N) An electromechanical system is described by the following flux-linkage vs current characteristic: 04 i- 01 x . . = It is operated on the closed cycle a - b - c - d - e as indicated below, with x constant during a - b and also c - d. The current is constant during b - c and also d - e. a b c d e i (Amps) i b i b (Wb turns) 8 c x (meters) .03 .03 .02 .02 .03 Find the following things: a) i b and c . b) The energy stored in the coupling field at points b and c. c) The force of electric origin at points b and c. d) Sketch this cycle in the vs i plane (label points a, b, c, d, and e) e) Sketch this cycle in the force vs x plane (label points a, b, c, d, and e) f) Is this is a motor or a generator?...
