Addressing power density and costs as major success factors for drivetrain solutions for e-mobility, a holistic system concept is necessary. Approaches which integrate e-machine, power electronics, control, gearing and cooling into a common housing offer high potential for compact and cost efficient (H)EV drivetrains. The transition to distributed multiphase inverter and motor concepts enables a novel level of system integration. A new smart stator tooth concept is presented. It comprises the integration of a segmented stator tooth together with dedicated power electronics and control electronics. This enables new degrees of freedom in terms of motor design, assembly and control.
