Method for manufacturing a wound rotor of an electric machine

摘要

A method for making a wire-wound rotating part for an electrically driven machine, wherein a sheet metal pack (13) and a commutator (16) spaced therefrom are attached to a shaft (10), and conductive strands are wound around the sheet pack (13) and the commutator (16) to form a generally ring-shaped winding. The method further comprises axially compressing the winding and simultaneously moving the commutator (16) closer to the sheet pack (13). The method is particularly useful for making electric fans for motor vehicles.
