Abstract: The present disclosure relates to electrical machines, such as liquid-cooled motors. The liquid-cooled motors can include a stator with cooling tube channels (e.g., corrugated channels) having tubes inserted and expanded. Lamination holes for each lamination in the lamination stack of the stator can have varying diameter along the axial direction to achieve a corrugated internal feature. The tubes for cooling liquid can be fitted in the lamination holes of the stator.
