 Abstract --Cost and compactness are major success factors for electrical drivetrains for (hybrid) electric vehicles (EV). To increase the system power density, the focus is set on system integration, meaning to integrate emachine, inverter, control, and gearing into one common housing. The inverter integration is facilitated by multiphase motors leading to lower phase powers and thus smaller inverter modules. To overcome price uncertainties of rare earth magnets, improved hard ferrite magnets are chosen as an alternative. In this paper, a new highly integrated drivetrain with a ferrite based 9-phase synchronous motor concept is presented with special focus on the main choices leading to the particular electromagnetic and mechanical design. The advantages of an integrated triplex inverter power supply and the new mechanical arrangement of a spoke-type rotor design will be presented, without focusing on the detailed electromagnetic behavior of the machine.

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

Many safety-critical applications especially in aviation require high power (mass) density generators with high reliability. While PM machines promise significant improvements in power density, and reliability, the widespread use of permanent magnet (PM) generators has been hitherto limited by the potentially detrimental effect of internal machine faults, caused by the lack of de-excitation capability during fault conditions. Even though there are several publications addressing fault-tolerant PM machines, most of these target auxiliary systems. In this paper, the detailed analysis, design and test results of a 175 kW main power fault-tolerant embedded PM generator for aerospace applications will be -presented. The design tradeoffs as well as the novel aspects of this machine will be discussed in detail.
