ate time invariant vector. Generally the Clarke transform uses three-phase currents <code>Ia, Ib and Ic</code> to calculate currents in the two-phase orthogonal stator axis <code>Ialpha</code> and <code>Ibeta</code>. When <code>Ialpha</code> is superposed with <code>Ia</code> as shown in the figure below </p>
