Advantages of integral slot winding

By Guest

Axial Flux Permanent Magnet Machines benefit from manufacturing advantages and reduction in end winding length through the use of tooth-concentrated fractional windings but display increased space harmonic content, leading to higher eddy current losses in the rotor iron and permanent magnets.

Fractional Slot Winding ~ your electrical home Fractional Slot Winding. Thus slots per phase is integral. While the pole pitch i.e. S/P is also fractional. Thus coil span can not be full pitch. When m is integer then the basic unit under a pole pair N and S keeps on repeating n the winding for any number of pole pairs. In fractional slot winding, in order to construct a basic unit,...
