Electric motor vehicle traction motor with stator having slot molding and liquid cooled end winding

A method for producing an electric vehicle traction motor, the traction motor including (i) a motor housing, (ii) a motor stator having a stator body with laminations and stator slots and a plurality of stator coils, wherein axial phase windings of the stator coils are arranged in the stator slots, and (ii i) an internal motor rotor which is separated fluidically from the motor stator, said method comprising the steps of:

• inserting a mold core having radially extending injection channels into a central opening of the motor stator;
• following the inserting step, injecting liquid potting material into the stator slots radially from an inside of the stator slots via the radially extending injection channels of the mold core as well as radially from an outside of the stator slots in order to form a slot potted body, such that the injected liquid potting material passes through the stator slots and exits the stator slots to protrude axially out of the stator slots thereby defining an overhanging portion of the slot potted body that overhangs the stator slots and an end-most lamination of the laminations of the stator body, wherein a shoulder is formed at an intersection of the overhanging portion and said end-most lamination of the stator body,
• inserting a motor rotor into the central opening of the motor stator, and
• installing the motor rotor and the motor stator into a motor housing.
