Abstract (en)
[origin: WO2022243422A1] The aim of the invention is to design a stator winding of a full metal stator (1) for an electric motor. This is achieved in that a stator laminated core (2) of the full metal stator (1) is equipped with an insulating end plate (14) according to a method. Stator teeth (6) protruding in the radial direction are wound with a winding wire (10). After a specified number of stator teeth (6), the winding wire (10) is guided away from the stator laminated core (2) and then back to the stator laminated core, thereby forming an at least U-shaped loop (24), and the loop (24) is then used to contact a motor electronic unit.
