Within this work, an application based comparison of electrical machines will be presented, carried out on the basis of a system approach. Today's most frequently used types of electrical machines, namely the induction machine, the switched reluctance machine, and the permanent magnet synchronous machine are used for comparison. Additionally, a fault tree analysis is presented for the electrical machine,...
This study presents a spoke-type permanent magnet synchronous motor (STPMSM) with a novel rotor which contains four individual iron core parts with flux barriers that are designed to realise a near-sinusoidal air gap flux density waveform. This novel type of rotor does not require thin bridges or retaining sleeves, the iron core parts of a rotor of this type are fixed to a non-magnetic sleeve by using...
This paper presents a generalized d-q model of multiphase (six-phase) induction motor in Matlab/Simulink. Further, to observe the advantages of six-phase induction motor over conventional three-phase counterpart, a comparative analysis is performed under similar conditions. It has been observed that the six-phase induction motor have several advantages over conventional three-phase counterpart, such...
In this paper, we present a comparative analysis of surface-mounted permanent magnet synchronous motors (SPMSM) and interior permanent magnet synchronous motors (IPMSM) for compressors of air-conditioning systems in electric vehicles (EVs). First, we use 2D finite element analysis (FEA) to analyze models satisfying the same rated conditions according to the torque-speed curve characteristics, which...
This paper deals three types of switched reluctance motors (SRMs) for fan drive. The three types considered are 6/4, 12/8 and 8/6 types. In this paper, not only the design of these three types of SRM, but also their performances are compared for the application of automotive cooling fan. The design parameters are calculated and selected by some constraint equations to match the requirements of the...
This paper is the article which researches the control algorithm applied to servo system of antenna sub-reflector, the main control algorithm is fuzzy sliding mode control algorithm. This paper first introduces the idea of fuzzy-sliding mode algorithm, then describes the background knowledge about applying to the antenna sub-reflector. The main content of this paper is simulation and comparative analysis,...
Little attention has been paid to the study of optimum variable-pitch control laws in the range of low tip speed ratios, as traditional Darrieus turbines operate in the range of high tip speed ratios. In this paper, we obtain the aerodynamic coefficients of the plate airfoil by the method of computational fluid dynamics (CFD). Then, an aerodynamic model is built based on Blade Element Theory, and...
This paper proposes a fuzzy control system that allows simulating experimental industrial loads coupled to electric machines rotor shaft. The main focus of the application relies on the improvement of a test bench that enables experimental essays before inserting the studied electric machine in the industrial process. In this paper, a direct current generator is coupled to a three-phase induction...
This paper presents system analysis, modeling and simulation of an electric vehicle with different sensorless control techniques. Indeed, sensorless control is considered to be a lower cost alternative than the position or speed encoder-based control of induction motors for an electric vehicle. Two popular sensorless control methods, namely, the Luenberger observer and the Kalman filter methods are...
In Part II a comparative analysis of the different brushless PM motor configurations, including exterior and interior rotor arrangements, salient and non-salient surface-mounted PM rotors, concentrated and distributed armature windings is presented. The comparative study is based on the developed design methodology given in the Part I of this paper. These motor configurations are investigated to be...
