IPMSMs used for industrial applications generally require high efficiency operation in a certain operating point or area in addition to constant torque operation. In this research, the examined motor demands high efficiency operation at high speed and high torque area. In this case, the current phase angle is small and it is difficult to use reluctance torque effectively. Furthermore, concentrated...
In rotating electrical machine design, the magnetic equivalent circuit based on the reluctance network method seems to be a fair tradeoff between computational time and precision. Therefore this paper deals with a semi-analytical calculation method of the direct and quadrature axis magnetic circuit in Reluctance Synchronous Machines (RSM) by the means of a nonlinear reluctance network. The corresponding...
Permanent Magnet Synchronous Machines (PMSMs) are complex systems where a great amount of physical phenomena are produced simultaneously. Most of the existing PMSMs models are based on empirical formulations and standard design rules which are not suitable for highperformance applications or optimized design processes. The aim of this paper is to present an improved PMSM model which offers a holistic,...
In this paper, a nonlinear magnetic circuit network model for the analysis of a three-phase 12-stator-slot/10-rotor-pole flux-switching permanent-magnet (FSPM) motor is proposed considering localized saturation effect, which enables the predictions of open-circuit air-gap field distributions, phase flux-linkage, phase back-electro-motive-force (back-EMF) and winding inductances waveforms. Further,...
