The earlier physical explanation not only permits the stator current space vector to be visualized, but it also simplifies the derivation of the electromagnetic torque, which can now be calculated on just this single hypothetic winding, rather than having to calculate torques separately on each of the phase windings and then summing them. Similar space vector equations can be written in the rotor circuit with the rotor axis-A as the reference. 2-6-1 Relationship between Phasors and Space Vectors in Sinusoidal Steady State Under a balanced sinusoidal steady-state condition, the voltage and current phasors in phase-a have the same orientation as the stator voltage and current space vectors at time t = 0, as shown for the current in Fig.
3-29), Eq. (3-31), and Eq. (3-32), respectively, we can label terminals in Fig. 3-10a,b with dλsq/dt, dλrd/dt, and dλrq/dt. 3-8 RELATIONSHIP BETWEEN THE dq WINDINGS AND THE PER-PHASE PHASOR-DOMAIN EQUIVALENT CIRCUIT IN BALANCED SINUSOIDAL STEADY STATE In this section, we will see that under a balanced sinusoidal steady-state condition, the dq-winding equations combine to result in the per-phase equivalent circuit of an induction machine that we have derived in the previous course . It will be easiest to choose ωd = ωsyn (although any other choice of reference speed would lead to the same results; see Problem 3-8) so that the dq-winding quantities are dc and their time derivatives are zero under a balanced sinusoidal steady-state condition.
In terms of resulting space vectors vsα_αβ = Rs is_ααβ + d α λs_αβ , dt (3-25) where vsα_αβ = vsα + jvsβ and so on. As can be seen from Fig. 3-5, the current, voltage, and flux linkage space vectors with respect to the αaxis are related to those with respect to the d-axis as follows: vsα_αβ = vs_dq ⋅ e jθda (3-26a) isα_αβ = is_dq ⋅ e jθda (3-26b) 38 ANALYSIS OF INDUCTION MACHINES IN TERMS OF dq WINDINGS and λsα_αβ = λs_dq ⋅ e jθda , (3-26c) where vs_dq = vsd + jvsq and so on.
