3-4b, similar to that in Fig. 3-4a. The same transformation matrix relates the rotor flux linkages and the rotor voltages in the equivalent A-B-C windings to those in the equivalent rotor dq windings. Same relationships apply to voltages and flux linkages. 3-3-1 Relating dq Winding Variables to Phase Winding Variables In case of an isolated neutral, where all three phase currents add up to zero at any time, the variables in a-b-c phase windings can be calculated in terms of the dq-winding variables.

3-1a at time t, phase currents ia (t), ib (t), and ic (t) are represented by a stator current space vector is (t ). A collinear magnetomotive force (mmf) space vector Fs (t ) is related to is (t ) by a factor of (Ns/p), where Ns equals the number of turns per phase and p equals the number of poles: isa (t ) = ia (t ) + ib (t )e j 2 π / 3 + ic (t )e j 4 π / 3 (3-1) and Fsa (t ) = Ns a is (t ). p (3-2) 30 ANALYSIS OF INDUCTION MACHINES IN TERMS OF dq WINDINGS We should note that the space vector is (t ) in Fig.
