Claims12
An electrical motor, comprising a rotor, a stator, and a housing enclosing the rotor and the stator, wherein the stator comprises at least one end turn connection device arranged on one axial end thereof, and a plurality of hollow winding pins extending through the at least one end turn connection device with conductive material wound around the plurality of hollow winding pins to form coils, wherein the at least one end turn connection device comprises a printed circuit board or a bus-bar assembly and wherein the at least one end turn connection device comprises all electrical connections between the coils.
A method for manufacturing an electrical motor, comprising arranging a rotor and a stator within a housing, wherein the stator is provided by:
- press-fitting a plurality of hollow winding pins onto at least one end turn connection device, and
- winding conductive material around the plurality of hollow winding pins to form coils around the plurality of hollow winding pins,
- wherein the at least one end turn connection device comprises a printed circuit board or a bus-bar assembly and comprises all electrical connections between the coils.
