Multiphase machines have attracted significant attention in academic and industrial sectors as candidates for high-power safety-critical applications and wind energy conversion systems. Premierly, this chapter introduces the state-of-the-art in multiphase machine winding topologies. This typically considers the winding layouts employed in multiphase induction machines with prime phase and multiple three-phase orders. This chapter also provides some recent winding topologies that offer better machine characteristics in terms of torque density, efficiency, and fault-tolerance capability. One of the major problems when dealing with a prime number of phases, either in academic research or industrial applications, is the special stator design. Thus, a general technique to rewind standard off-the-shelf three-phase stator frames with any general prime phase order is introduced while preserving the same copper volume.
