Splet01. sep. 2016 · The short-pitched STLSRM. Another possibility for STLSRM is that created using the short-pitched winding as shown in Fig. 4 for the three-phase STLSRM. Similar to the full-pitched STLSRM, each slot is filled completely with conductors of a coil related to a phase but each coil is wrapped here around one stator pole. Splet02. mar. 2024 · Pitch factor is defined as the ratio of the induced emf per coil when the winding is short-pitched to the induced emf per coil when the winding is full pitched. It is given by K p = cos (α/2) Where α is the short pitch or chording angle. Calculation: Given that, Slots S = 72. Slots/pole/ph = m = 72/ (8×3) = 3. Pole pitch = S/P = 72 / 8 = 9 Splet25. nov. 2024 · Meanwhile, because the stator flux is short and the stator flux has no reversal, the core loss of the proposed 6/5 type is lower than that of the traditional 12/8 type.
