Abstract
The invention is the compact multiphase wave winding of a high specific torque electric machine The invention is the compact multiphase wave winding () of the electric machine. Winding () is filling the slots () of the stator ferromagnetic core () and comprise one or multiple layers (). Winding () fills the slots (). Winding comprise N or a multiple on N conductors (), where N represents the number of winding phases. Conductor () comprises or is assembled by parallel straight segments () and winding overhangs (). Between the two straight segments () of one conductor () there are N teeth () and N−1 slots () or N+1 teeth () and N slots (). Straight segments are connected by winding overhangs which shape in tangential axial plane differs for less than one sixth of magnetic period () from ellipse shape with one axis equal to half of magnetic period () and other axis length between half and three quarters of magnetic period () length.
