Basic procedure for machining of stator housings
Stator housing external machining

External Machining stator housing

External machining of stator housings for electric motors is a demanding task. These housings, which often come in tubular or pot-shaped designs, are crucial for the efficiency of the electric motor. Several challenges have to be overcome during the process. The thin-walled aluminium housings with integrated ribs for the cooling circuit require the highest precision in terms of diameter accuracy, shape and position tolerances. The concentricity between different diameters is of huge importance.
