This paper suggests the reasonable switching frequency determination method for achieving highest efficiency of the railway propulsion system consisting the silicon carbide (SiC) inverter and permanent magnet synchronous motor (PMSM). The SiC power device allows increasing the switching frequency of the inverter because it has the small switching power loss. The total efficiency is taken into account for determining the switching frequency of SiC inverter in this paper. In the efficiency analysis of SiC inverter and PMSM, the PMSM drive control is considered with the hybrid switching method combined the synchronous PWM and asynchronous PWM. The result of the analysis shows the efficiency curve of propulsion system depending on the switching frequency. The switching frequency having the minimum power loss of propulsion system is selected based on the extracted power loss curve.

An axial-axial flux compound-structure permanentmagnet synchronous machine (CS-PMSM), which is a hybrid electric vehicle (HEV) power train concept, is a structural integration of two axial flux permanent-magnet synchronous machines. It is a novel electromagnetic device with dual mechanical ports and dual electric ports. In this paper, several candidate electromagnetic schemes for the CS-PMSM are analyzed and compared with 3D finite-element method (FEM), and an optimum tradeoff choice for the prototype machine is established. The axial magnetic force, which is unilateral and very important for the assembly, operation and choice of bearings, is evaluated using 3D FEM. A downsized prototype machine of the CS-PMSM was manufactured. The experiments were performed. The magnetic and mechanical designs are evaluated by experimental results.Keywords-Axial-axial flux; compound-structure permanentmagnet synchronous machine; electromagnetic scheme; soft magnetic composite (SMC).I.

“…SMC is brittle so that in core production it is better to use a molding technique rather than machining a pre-formed sample. Some papers have addressed the molding of parts, i.e., a modular technique [24]- [25], but this still needs a large number of costly pressing and assembly stages. The ideal process should be that the core is pressed in one single step and that the coils can be easily fitted.…”

SMC (soft magnetic composite) materials and SMC electrical machines have undergone significant development in the past decade. For the molding of the SMC core, if a high productivity low pressure press is used, the manufacturing cost can be dramatically reduced. However, the magnetic properties of the SMC core and the machine performance are highly dependant on the mass density of the core. This paper presents the development of a claw pole permanent magnet motor with a low mass density SMC stator core molded at low pressure which can replace the existing single phase induction motor in a dish washer pump. The developed SMC motor has been prototyped and tested. Both the parameter computation and performance prediction are validated by the experimental results. These show that the low mass density SMC core is suitable for low cost mass production of SMC electrical machines.Index Terms-Claw pole motor; Low pressure molding; Magnetic field finite element analysis; Molded core; Phase variable model; Permanent magnet motor; Soft magnetic composite (SMC).
