Consider Example 12.4.1. With the assumed current-source excitations of part (c), determine the voltages induced in the stator and rotor windings at the corresponding angular velocity ωm at which an average torque results.

Example 12.4.1

Consider an elementary two-pole rotating machine with a uniform (or smooth) air gap, as shown in Figure E12.4.1, in which the cylindrical rotor is mounted within the stator consisting of a hollow cylinder coaxial with the rotor. The stator and rotor windings are distributed over a number of slots so that their mmf can be approximated by space sinusoids. As a consequence of a construction of this type, we can fairly assume that the self-inductances Lss and Lrr are constant, but the mutual inductance Lsr is given by
