The paper present the analysis of the performances of an electrical machine used for small power automotive application. The electrical machine under study in this paper is a small flux synchronous reluctance machine (SynRM) with 4 poles and 24 slots. The analysis of studied machine will be carried out both analytically and numerically in SPEED program and(More)
Nowadays there is a serious trend to design electrical machines for propulsion units as cheep as possible. Machines that lack the permanent magnets having performances close to those that embed permanents magnets represent now the main interest in this field. Such a machine is the variable reluctance synchronous machine. Being derived from the family of(More)
The present paper describes a CAD platform that combines analytical design, numerical electromagnetic and vibro-acoustic analysis of Permanent Magnet Synchronous Machines for automotive drives systems with a large range of rated power. For dynamic validation and transient behavior two control strategy were taken in consideration (speed and torque control).
In automotive applications detailed multi-domain modeling and testing at component and sub-component level is necessary to improve the understanding and design capabilities for higher performances and lower costs. New and faster tools are required to reduce the development and testing time and effort for electrical actuated automotive sub-systems. The paper(More)
From aerospace to automotive, and from telecommunications to medical devices, high reliability and performance driving systems are required [2]. The present paper aims the design and analysis of Permanent Magnet Synchronous Machines (PMSM) with external rotor topology for direct-driven compact centrifugal pump systems. The whole CAD process, using both(More)
The paper approaches the high-frequency equivalent circuit of permanent magnet synchronous machines (PMSM) with different pole number, and its response to PWM-based supplying current. The model is implemented in MATLAB-Simulink, and the phase currents, as well as the common and normal mode currents are analyzed.
In this paper, a simplified high frequency model of the Permanent Magnet Synchronous Motor (PMSM) as well as the motor drive were developed and analyzed using Simulink. The currents in the normal and common mode paths were extracted and compared with the analytical results. A Finite Element Analysis (FEA) was performed on two PMSM with different topologies(More)
Synchronous Reluctance Machines (SyncRM), began to draw a lot of attention in last decade and presently receives a great deal of interest, since the cost of active materials is much lower than for a Permanent Magnet Synchronous Machine. For automotive applications a high torque and power density, low torque ripple and a wide speed range is required. The(More)
