Modular three-phase machines with laminated winding for hybrid vehicle applications

A design model development for electrical machines with laminated windings is presented. The focus is to provide manufacturable solutions for commercial vehicle traction applications. The machine is designed with axially distributed single-layer wave-winding segments with a core that builds a modular three-phase machine. The phase segment, whose central part is a wave-winding made as a laminated winding, form a semi-claw pole structure. A conventional permanent magnet synchronous machine is used as a reference. The result indicates that comparable torque and power can be reached with the suggested alternative design.
