Fractional Slot Concentrated Winding. This means that all coil sides of a certain phase are concentrated in a single slot under one pole thus requiring deep slots.

In the emetor winding calculator fractional slot windings with a number of slots per pole per phase strictly superior to 1 are indicated with orange cells. This means that all coil sides of a certain phase are concentrated in a single slot under one pole thus requiring deep slots. These are characterized by fractional slot per pole and per phase lower than unity resulting in dense harmonic contents of the armature mmf with a number of pole pairs lower than the field one.
This means that all coil sides of a certain phase are concentrated in a single slot under one pole thus requiring deep slots.
This statement is much more critical in fractional slot concentrated winding permanent magnet synchronous machines also named fractional slot permanent magnet machines fspmms. These are characterized by fractional slot per pole and per phase lower than unity resulting in dense harmonic contents of the armature mmf with a number of pole pairs lower than the field one.
