Problem 4-1 DC Excitation of Induction Machine
Consider a three phase induction motor in which stator phases b and c are con-
nected to a de current source of amplitude Ide. Phase a is left disconnected.
Use a stationary reference system with o = 0 and find:
a) the stator d and q currents;
b) the stator d and q steady state voltages if the rotor speed is constant at
Or, (rad/sec);
c) the rotor currents for the condition of part (b);
d) the torque as a function of the de current, the rotor speed and the
machine parameters.
