This paper describes the optimum design of a permanent-magnet-assisted reluctance rotor of a 110 kW reluctance synchronous traction machine. Previous studies show that the performance of the pure reluctance synchronous machine drive deteriorates fast in the flux-weakening speed region. To address this problem, thin bonded permanent-magnet sheet material is used inside the flux barriers of the r...

This paper deals with the optimal control of interior permanent magnet synchronous machine (IPM) in the integrated starter-generator (ISG) application. IPM designed for flux-weakening operations are able to realise high performances. Nevertheless, the ISG environment imposes lots of constraints which must be taken into account in an appropriate control. After a presentation of machine design, I...

The radial-radial flux compound-structure permanent-magnet synchronous machine (CS-PMSM), integrated by two concentrically arranged permanent-magnet electric machines, is an electromagnetic power-splitting device for hybrid electric vehicles (HEVs). As the two electric machines share a rotor as structural and magnetic common part, their magnetic paths are coupled, leading to possible mutual mag...

This paper presents the dynamic characteristics of the transverse flux linear motor (TFLM) with permanent magnet (PM) excitation, which has E-shaped core. Because of the inherent feature of TFLM with PM excitation that the flux flow path is threedimension, the solid type stators and mover cores are used. In case of adoption of solid type stators and mover cores, as the motor speed is increased,...

SIS100 will be operated with high intensity heavy-ion and proton beams. In order to avoid coherent beam instabilities, the reduction of the overall ring impedance is of great importance. The extraction kicker system is one of the main contributors to the overall ring impedance. This paper focuses on the contribution of the external electrical network to the kicker impedance. Previous calculatio...
