it reduces stator copper loss by wa

it reduces stator copper loss by way of an ultra-high fill-factor stator manufactured by an ultra-high density wire winding method and by way of a new 2-way cooling structure. It also reduces stator iron loss by way of a thin and high-grade electromagnetic steel stator core. Finally, it reduces rectification loss by way of a new Metal-Oxide-semiconductor Field-Effect-Transistor module.
