In topic 6, we define and illustrate space vectors of induction motor variables in the stator reference frame, dq. Dynamic equations of the induction motor are expressed in this frame. The idea of a revolving reference frame, DQ, is introduced to transform the ac components of the vectors in the stator frame into dc signals, and formulas for the straight and inverse abc—»dq and dq—»DQ transformations are provided. We finish by explaining adaptation of dynamic equations of the motor to a revolving reference frame.
