Method for manufacturing core layer sheet for electromotor, involves forming stator slots in round-shaped metal layer, and separating round-shaped metal layer from rotor layer sheet and stator layer sheet

摘要

The method involves cutting (S41) a round-shaped metal layer comprising an axle opening. Several stator slots are formed (S42) in round-shaped metal layer. The round-shaped metal layer is separated from rotor layer sheet and stator layer sheet. Several cooling vents and rotor slots are formed (S43) in rotor layer plate.
