What is Integral vs. Fractional Slot Windings about?

1. Integral and fractional slot windings refer to whether the number of slots per pole per phase is an integer or fractional number. Fractional slot windings reduce harmonics in the EMF and MMF waveforms. 2. The pitch factor is the ratio of induced EMF when coils are short pitched versus fully pitched. It is always less than 1 and depends on the harmonic order. 3. The distribution factor is the ratio of induced EMF when coils are distributed versus concentrated in slots. It also is always less than 1 an
