    In this paper, a novel type of hybrid reluctance motor (HRM) drive is presented. This new motor is characterized by a stator formed by a combination of independent magnetic structures, each one composed of an electromagnet, the magnetic core with one or several coils wound on it, associated with a permanent magnet disposed between their poles. The rotor has the same configuration of a switched reluctance motor (SRM) without any coil, magnets, or squirrel cage. A particular case of this HRM, with three electromagnets with permanent magnets in the stator and five salient poles in the rotor, is studied. The motor is then analyzed and simulated. Finally, experimental results are given, and this type of motor drive is compared with the SRM drives of the same size. This new type of HRM does not present cogging torque and has higher power and efficiency than an SRM of the same size.

    In the next years is expected an important rise in sales of electrical scooters in the entire world but especially in China. In order to address this challenge the electric scooter industry has to be more competitive in the transportation market and therefore important improvements, in terms of energy density and costs, have to be done in the electric storage system and in the electric propulsion system. In this paper, an analytical and experimental comparison of two different drives for electric scooters is carried out. Both are permanent magnet synchronous outer rotor motor drives but one placed inside the rear wheel and the other connected to the wheel trough a mechanical transmission.

    Herein is reported development and testing of a life cycle analysis (LCA) procedure for assessing the environmental impact of induction motors. The operating conditions of a given industrial application are defined by the mechanical power required, operating hours and service life of the three-phase induction motor involved. Based on manufacturer’s data mainly,different three-phase induction motors for various sets of operating conditions, including oversizing, have been selected. To quantify the environmental impact of each motor, the Methodology for the Ecodesign of Energy Using Products (MEEUP) was applied, according to the quantity of each of the motor’s main constituent materials used in the production phase, and to the two operating variables that directly influence the LCA results: output power and efficiency. The procedure was applied to different three-phase induction motors representing two efficiency categories (IE1 and IE2) and considering different oversizing possibilities. The total environmental impact of each motor was determined based on the production, service life and end-of-life phases. The best motor option was identified for different operating conditions. Given the potential for energy savings in electric motors, LCA-based environmental impact assessment should be performed when different motors are being evaluated for a given industrial application.

    Torque ripple is an inherent characteristic of switched reluctance motor drives due to its double salient geometry and it is a serious drawback in applications that require smooth torque and high dynamic performances. This paper presents some contributions to the minimization of torque ripple in SRM using direct instantaneous torque control (DITC). Direct torque controller is simulated using Matlab/Simulink and then implemented in a DSPACE ACE kit 1006 CLP that includes a processor board with an AMD OpteronTM running at 2.6 GHz. Finally, experimental results are shown and they are compared with those obtained using conventional angle control.

    Torque ripple is an inherent characteristic of switched reluctance motor drives due to its double salient geometry and it is a serious drawback in applications that require smooth torque and high dynamic performances. This paper presents new contributions to the minimization of torque ripple in SRM using an enhanced direct instantaneous torque control. Torque ripple is reduced by adding a PI controller before the instantaneous torque controller and a change in the commutation zones. The PI direct instantaneous torque controller (PI+DITC) is simulated using Matlab/Simulink and then implemented in a DSPACE ACE kit 1006 CLP. Finally, experimental results are shown and they are compared with those obtained using conventional direct instantaneous torque control.

    Purpose Herein is reported an application of life cycle analysis (LCA), using the Methodology for the Ecodesign of Energy Using Products (MEEUP), in order to assess the influence of some design parameters in the environmental impact of three-phase induction motors. A motor design procedure to minimize the total environmental impact, based on data obtained from commercial motors, is presented. This procedure is specially intended for the low power range due to the greater potential for energy savings in motors having an output power of 0.75 to 4 kW. Methods A procedure has been developed, based on previously acquired data, to determine the parameters required for application of the MEEUP methodology. These comprise the quantity of each of the motor's main constituent materials used in the production phase, and the two operating variables that directly influence the LCA results: output power and efficiency. Results and discussion The procedure was applied to two 1.5 kW induction motors of different efficiency (according to standard IEC60034-2-1). The calculation results were compared satisfactorily with the laboratory test results. The total environmental impact of the two real motors and of the proposed motor was determined in the production, service life, and end-of-life phases.

    This article presents a new comprehensive design procedure for longitudinal flux flat linear switched reluctance motors. The design process comprises all the steps from detailing the specifications to sizing the prototype to validating the design, and it can be applied to three types of flux flat linear switched reluctance motors: single sided, double sided, and modified double sided. The design is based on an analytical formulation of the average translation force determined using a simplified non-linear energy conversion loop. Special emphasis is devoted to the calculation of the number of turns per phase. A two-dimensional finite-element analysis, corrected to take into account end effects, and a lumped parameter thermal analysis were used to refine and/or validate the design. Finally, a linear switched reluctance motor prototype was built following the proposed design and was verified by experimental measurements.

    The purpose of this paper is to provide an analytical approach to the thermal behavior of a longitudinal flux flat linear switched reluctance motor (LSRM) suitable for the early stages of motor design. The approach uses a thermal model based on lumped parameters and adapted to the particularities of LSRMs. The thermal network is solved using the widely recognized Matlab-Simulink software. The proposed analytical approach was verified by means of experimental measurements and thermographic analysis.

    The prediction of switched reluctance motor (SRM) performance requires knowledge of core losses. However, the calculation of iron losses in SRM is especially complex first because the flux waveforms are nonsinusoidal and different parts of the magnetic circuit have different waveforms and second because they are conditioned by the type of control used. This study proposes an analytical method for calculating core losses that comprises simulation of the SRM using finite element analysis to determine the magnetization curves, and SRM modeling, which enables transient simulations with the associated electronic power converter run under different control strategies. The flux density waveforms in the different parts of the SRM are derived from the flux density waveform of the stator pole that is obtained from the transient simulation. The specific core losses (in W/kg) are separated into three parts (hysteresis losses, classical eddy current losses and excess losses) and calculated using the waveforms and time derivatives of the local flux density. The core losses for each part of the SRM’s magnetic circuit can be estimated using the calculated values for specific hysteresis losses, specific classical eddy current losses and specific excess losses for each zone. Adding these individual losses yields the total core losses. The method was applied to three-phase 6/4 SRM, and the calculated results were compared with experimentally obtained measurements.

    This paper presents a detailed sensitivity analysis of the effect of several geometrical parameters on the performance of a double-sided linear switched reluctance motor (LSRM). The analysis was conducted in two dimensions using finite-element method and takes into account only one part of the LSRM. This paper first investigates the powerful influence of stator- and translator-pole widths on force profiles. It then shows how these performance parameters are influenced by stator-pole length, translator-pole length, stack length, yoke length, and air gap. Experimental results confirm that the 2-D finite-element sensitivity analysis proposed in this paper may prove to be a useful tool for optimizing the geometry of a double-sided LSRM.

    In this study two electromagnetic analytical models have been developed. From this models the main magnetic and mechanics characteristics are obtained, and also permit getting the principal dimensions of the LSRM. From this results a prototype has been built, which has been examined by means of finite elements and experimental tests which corroborate the validity of the contributed analytic models. The study contains the status of art and the classification of the linear actuators as well as the genesis of the LSRM from the rotative counterpart. The LSRM performance is simulated in a Matlab/Simulink simulation model. This model allows us to know the influence of the position shot for the phase current on the average force and therefore the optimal interval conduction phase current. Chapter 2 deals with a new electromagnetic model obtained from analytical simple expressions which permit analyzing and obtaining parameters with a reduced computational cost. Also is studied the endeffects (fringe effects) by analytical expressions and by finite elements. With the objective of quantifying the aforementioned effect on the linked flux versus current characteristic, a correction method is developed. Chapter 3 investigates the influence of the geometric dimensions on the profiles of force and inductance using the method of the finite elements. The geometric relations that optimize the average force are reported. Chapter 4 presents the study of the principal losses of the LSRM, mainly iron losses and copper losses. Once losses have been obtained, an analytical thermal model of lumped parameters is developed from which the thermal behavior is predicted. Chapter 5 presents a systematic methodology for designing the LSRM. This methodology allows us to obtain the main parameters (electric, magnetic, mechanic and geometric), from the given design specifications. The methodology is validated by finite elements. In chapter 6 the analytic models are validated by the construction and essay of a prototype. The experimental results validate the contributions made in this study.

    En esta Tesis se hacen contribuciones al estudio, a la caracterización y al dimensionamiento de los motores lineales de reluctancia autoconmutados de flujo longitudinal y topología plana. En el capítulo 1 el estudio contiene el estado del arte y una clasificación de los accionamientos eléctricos lineales. A continuación se desarrollan los principios fundamentales del motor de reluctancia autoconmutado rotativo (SRM) a partir de una estructura magnética de reluctancia elemental. Seguidamente en base a la estructura del SRM se efectúa una génesis del motor lineal de reluctancia autoconmutado (LSRM), se presentan las ecuaciones que lo caracterizan y se propone un modelo para explicar su comportamiento utilizando el entorno MATLAB/Simulink. En el capítulo 2 se aborda el análisis magnético del LSRM utilizando tres procedimientos distintos. El primero de los cuales se basa en la determinación del área del ciclo de conversión de la energía, en el cual la curva de magnetización en la posición no alineada se representa por una línea recta mientras que la curva de magnetización en la posición alineada es representada por dos líneas rectas. Mediante este procedimiento se determina la ecuación de la fuerza de propulsión media del LSRM en función de la densidad de flujo magnético en los polos del estator, de la densidad de corriente y de la geometría del motor. El segundo procedimiento consiste en analizar el circuito magnético mediante parámetros concentrados considerando la saturación y los efectos asociados a las cabezas de bobina. Finalmente, el tercer procedimiento es el análisis magnético mediante elementos finitos en 2D corregido para tener, también, en cuenta los efectos relativos a las cabezas de bobina. En el capítulo 3 se realiza un análisis de sensibilidad investigando la influencia de las principales dimensiones geométricas sobre los perfiles de fuerza e inductancia del LSRM, utilizando el procedimiento de análisis magnético mediante elementos finitos en 2D corregido para considerar de los efectos asociados a las cabezas de bobina. A partir de los resultados obtenidos se obtiene las relaciones geométricas que optimizan la fuerza media de propulsión. En el capítulo 4 se estudian las pérdidas en el hierro y de las pérdidas en el cobre en el LSRM. Desarrollándose, seguidamente, un modelo analítico de parámetros concentrados que describe el comportamiento térmico del LSRM., mediante el cual será posible predecir las temperaturas máxima y media en función de las pérdidas totales. En el capítulo 5 se realiza, en base a los resultados obtenidos en los capítulos anteriores, una propuesta de dimensionamiento del LSRM que facilita un diseño optimizado de los principales parámetros eléctricos, magnéticos, mecánicos y geométricos a partir de unas determinadas especificaciones de diseño. En el capítulo 6 se presentan los resultados experimentales efectuados en el laboratorio, sobre un prototipo de LSRM, construido en base a los estudios precedentes, que validan las propuestas efectuadas en la Tesis. Finalmente en el capítulo 7 se recogen a modo de conclusión las principales aportaciones de esta Tesis y se sugieren futuras líneas de investigación.

    This paper compares the environmental and life cycle impact of one switched reluctance motor (SRM) drive and two inverter-fed induction motor (IM) drives. The study was carried out according to the Directive on the Ecodesign of Energy-Using Products (EuP 2005/32/EC) and following the Methodology for the Ecodesign of Energy-Using Products (MEEUP). The following base-case models were used: an IM (Eff3), an IM (Eff1) and an 8/6 SRM. All of these base-case models are rated at 1.5 kW of output power and are considered to be representative of the low-power range. The analysis shows that SRM drive has a lower environmental impact than the IM drives and offers a high savings potential, comparable to, or even greater than that of the IM (Eff1) in the use phase.

    In this paper, switched reluctance motors (SRM) are proposed as an alternative for electric power assisted steering (EPAS) applications. The new 42 V power voltage system is a very attractive design for a steering electric motor, both from a cost and size perspective. A four-phase 8/6 SRM drive is designed for a rack type EPAS which should provide a maximum force of 10 kN. Two-dimension finite element analysis is used to validate the design.

    This paper compares the environmental and life cycle impact of one switched reluctance motor (SRM) drive and two inverter-fed induction motor (IM) drives. The study was carried out according to the Directive on the Ecodesign of Energy-Using Products (EuP 2005/32/EC) and following the Methodology for the Ecodesign of Energy-Using Products (MEEUP). The following base-case models were used: an IM (Eff3), an IM (Eff1) and an 8/6 SRM. All of these base-case models are rated at 1.5 kW of output power and are considered to be representative of the low-power range. The analysis shows that SRM drive has a lower environmental impact than the IM drives and offers a high savings potential, comparable to, or even greater than that of the IM (Eff1) in the use phase.

    This paper describes an electronic device that enables AC contactors to ride through power quality dsturbances. The proposed device is connected to the contactor coil and consists of a power conversion excitation and hold-in crcuit, a control circuit, an immunity circuit and a shutdown circuit. It does not disturb contactor operation, is easy to use nd can be built from cheap, commercially available components. Experimental tests have demonstrated the efectiveness of the proposed electronic device for improving the immunity of AC contactors during power quality disturbances, particularly voltage dips.

    In this paper a photovoltaic solar pumping system using a new linear actuator is presented. This linear actuator is a double-sided flat two-phase variable-reluctance linear stepper motor that moves a piston-type water pump with the help of a rope, a pulley and a counterweight. The entire actuator pump ensemble is controlled by a simple electronic unit that manages the electric power generated by a photovoltaic array. The proposed system is suitable for rural communities in developing countries because it is reliable, affordable and easy to maintain.
