Opis:
The paper presents simulation results for a two-module reluctance motor (Transverse Flux Motor) with an outer rotor. The two-module TFM construction is compared with a classical, three-module one. A specific shape of teeth is used to obtain a non-zero start torque. Calculations of the magnetic field and electromagnetic torque are performed using the Flux3D package based on the finite element method. In particular, the paper analyses the influence of the new motor magnetic circuit construction on the torque produced by the motor and its pulsations. The calculations enable to determine electromechanical parameters for a specific motor under design without making its costly prototype. A number of computer simulations are carried out and the results are compared with the three-module prototype version of the motor.

Opis:
W artykule przedstawiono sposób modelowania indukcyjności uzwojenia fazowego silnika reluktancyjnego przełączalnego (SRM) oparty na metodzie sieci reluktancyjnych (MSR). Model pozwala wyznaczyć przebieg indukcyjności własnej uzwojenia fazowego w zależności od kąta położenia wirnika, dla różnych wartości parametrów geometrycznych silnika (m.in. szerokości biegunów stojana i wirnika). Model uwzględnia nieliniowość magnetyczną rdzenia. Artykuł zawiera opis konstrukcji bazowej analizowanego silnika, opis procedury wyznaczania indukcyjności uzwojenia oraz przykładowe wyniki otrzymane przy użyciu modelu. Dla różnych wartości wybranych parametrów geometrycznych pokazano przebiegi kątowe indukcyjności oraz jej pochodnej względem kąta położenia wirnika i porównano je z wynikami obliczeń polowych oraz wynikami otrzymanymi przy użyciu podobnego modelu innego autora. Ponadto pokazano wyniki wstępnej analizy wrażliwości parametrów przebiegu kątowego indukcyjności (zdefiniowanych tak, aby charakteryzowały moment) na zmiany geometrii silnika. Model zostanie wykorzystany do optymalizacji konstrukcji silnika. Model został zaimplementowany w środowisku MATLAB.
A method of determining inductances of a switched reluctance motor (SRM) based on reluctance network analysis has been presented in the paper. The model allows calculating a self inductance function of one phase versus rotor angular position, for a few variable parameters of the geometry (e.g. a width of the rotor and stator poles). The model takes into consideration the magnetic non-linearity of a core. The paper comprises a description of a base construction of the analyzed motor, a procedure of calculating the inductance and results obtained by means of the model. Inductance functions and their derivatives versus rotor angular position for selected variable parameters of the geometry have been presented for the proposed model, an earłier model of another author, and finite element calculations. Moreover, a sensitive analysis has been performed for the inductance function as well as three criterial functions assumed to be used in optimization. The model is designed to optimize of the SRM construction. The model was implemented in the MATLAB environment.

Opis:
There was presented a frequency multiplication of a single, binary rotor position feedback signal implementation in the article. This technique was necessary to achieve wide-speed control range and improved dynamics. In the beginning a basics of the switched reluctance motors construction were described as the control system challenges were. A nature of the reduced up to one position feedback signal interface line was shown as the reference for phase locked loop system. The problem of low resolution and asymmetrical shape of the mechanical position sensor was described with its solving by embedded system optimized SPLL loop usage. There were appropriate theory dependencies introduced for phase locked loop system as confirming experimental results were shown. In the summary, conclusions were made and the further research steps were proposed. Additionally, custom made drive system for switched reluctance motor and the motor as the control object itself were introduced.

Opis:
An approach helpful when developing an optimized construction of a 6/4 type switched reluctance motor (SRM) is described in the paper. The analytical modeling procedure, based on the reluctance network method and analytical solution of an ordinary differential equation, enables applying a gradient optimization routine and better control of optimization process. The model allows for estimation of the efficiency, torque, and acoustic noise of the motor taking into account the magnetic non-linearity and the control algorithm to keep a constant input power. A bicriterial optimization routine has been applied to find optimal constructions. Eleven geometric and winding parameters are supposed to be the optimization quantities. Analyzed constructions – the initial one and the optimized ones, were validated by means of FEM calculations. The proposed approach can be employed in designing the SRM to be a drive motor in an electrical vehicle, at least as a first attempt.

Opis:
The paper presents dynamics simulation results for the three-module reluctance motor (Transverse Flux Motor -TFM) with an outer rotor. Calculations of the most important integral parameter used in the circuit model, are performed using the Flux3D package based on the finite element method. A mathematical model for a dynamics analysis of TFM is built in the Matlab/Simulink environment. The model has a hierarchical structure with its fundamental part being a single phase-belt of the motor. The basis for the construction of the laboratory setup is a DS1104 R&D Controller Board with a CP1104 Connector Panel. The experimental validation is divided into two parts. In the first step, the mathematical model of TFM under steady-state operation is examined. In the second step, experimental validation of the results obtained from the dynamical circuit models is performed. Results of the simulations, confirmed by the experimental validation presented in this work, allow to determine the most important characteristics of TFM in both dynamic and steady-state conditions.

This article introduces the switched reluctance machine operating as a generator. This kind of electrical machine delivers CC power at the output and the energy generated can be controlled through several variables. In this work, the switching angles of the machine's power converter are optimized using deterministic and heuristic techniques so that the output power is kept constant via PI controller while guaranteeing maximum value for machine performance, even for different excitation values and mechanical power on the shaft.

Opis:
This paper presents optimization results for a two-phase, modular transverse flux switched reluctance motor (TFSRM) with an outer rotor. In particular, the main disadvantage of the considered motor structure, that is the zero starting torque in some rotor positions, is eliminated by construction optimization. A numerical model of the motor developed in the Flux3D program is coupled with a Matlab-based evolutionary algorithm for optimization of construction parameters of the magnetic circuit. The elaboratem algorithm is also connected with a database to limit the computation costs. Three objective functions are taken into account for the motor integral parameter improvement. The fundamental role of a type of an optimization criterion function is comparatively analyzed and a new effective criterion function is introduced.

Opis:
In the paper, the modified (compared to the classical asymmetric half-bridge) converter for a switched reluctance machine with an asymmetric rotor magnetic circuit was analysed. An analysis for two various structures of switched reluctance motors was conducted. The rotor shaping was used to obtain required start-up torque or/and to obtain less electromagnetic torque ripple. The discussed converter gives a possibility to turn a phase off much later while reduced time of a current flows in a negative slope of inductance. The results of the research in the form of waveforms of currents, voltages and electromagnetic torque were presented. Conclusions were formulated concerning the comparison of the characteristics of SRM supplied by the classic converter and by the one supplied by the analysed converter.

Opis:
The paper presents an algorithm for the construction of an approximation of a highly nonlinear current-flux characteristic of a synchronous reluctance machine. Such an approximation is required in a Hamiltonian model of an electric machine and the constructed approximation is suited to be used in such a model. It employs a simplicial approximation based on irregular points sets in the spaces of currents and fluxes. The sets are constructed by the iterative insertion of new points. Initially the sets contain an arbitrarily small number of elements. The insertion is based on an approximation error calculation. Based on the sets containing possibly small number of elements, the proposed procedure leads to smooth and precise approximation. Due to the nonlinearity of the approximated characteristics, ambiguities can occur. A method for the triangulation refinement of the sets of currents and fluxes that eliminates them is also presented. In the paper, a reluctance machine model using the constructed approximation is described and compared with a model using the approximation based on regular sets.

Opis:
In the paper a new measurement procedure of identification of synchronous reluctance motors parameters is presented. It is based on extension of traditional current decay test, used both in case of induction and synchronous motors [1, 3]. The main aim of the method is to enable to obtain the current-flux linkage characteristic necessary in case of Hamiltonian model of the machine (eq. 1). In case of 3-phase machine without neutral wire, being the most popular in practical applications [3], the method is based on measurement of currents in two independent phases (Fig. 4, eq. 5). The result of its application in a form of trajectories presenting traces of the chosen flux linkage in a current space is shown in Fig. 8b.

Opis:
Switched Reluctance Machines (SRMs) applied in adjustable speed drives are receiving during the last two decades considerable attention from industry since they are characterised by rigid construction, high operation reliability, high efficiency and last but not least low manufacturing costs. The successful realization of a SRM drive for industrial application demands inter alia of the determination of the best motor construction from the point of view of the requirements of considered drive. A new hybrid design method for SRM drives with application of analytical calculation methods, finite element method and simulation models is proposed in this paper. The calculation/design system is characterised by important effectivity and reliability. The correctness of the proposed design algorithms is verified by laboratory tests made on two motor prototypes manufactured for concrete industrial applications.

Opis:
The paper deals with a single-phase reluctance motor used to test the motion equations of an electromechanical system. The identification of the motor electric parameters as a function of the rotation angle of the rotor was carried out using AC 50 Hz voltage source. A mechanical part of the system was designed as a physical pendulum containing the motor rotor and a metal bar mounted on the rotor axis. The parameters of the mechanical part were measured during the pendulum oscillations. The work presents the characteristics and motion equation parameters of the motor dynamics. The reluctance motor motion equation does not fullfil the power balance. The parameters of the motion equations obtained from the experiment and from the second order Lagrange’a equations are compared. The derivation of motion equation, together with a discussion of holonomicity of electromechanical systems is also presented.
