Authors: Andrada Gascón, Pedro; Blanqué Molina, Balduino; Martínez Piera, Eusebio; Torrent Burgués, Marcel; Perat Benavides, Josep Ignasi; Sánchez López, José Antonio
Abstract: 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.</description>

      <description>Title: Minimization of torque ripple in switched reluctance motor drives using direct instantaneous torque
Authors: Castro Soriano, Javier; Andrada Gascón, Pedro; Blanqué Molina, Balduino
Abstract: 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&#xD;
smooth torque and high dynamic performances. This paper presents some contributions to the minimization of torque ripple&#xD;
in SRM using direct instantaneous torque control (DITC). Direct torque controller is simulated using Matlab/Simulink and then&#xD;
implemented in a DSPACE ACE kit 1006 CLP that includes a processor board with an AMD OpteronTM running at 2.6 GHz.&#xD;
Finally, experimental results are shown and they are compared with those obtained using conventional angle control.</description>

      <description>Title: Assessing the environmental impact of induction motors using manufacturer's data and life cycle analysis
Authors: Torrent Burgués, Marcel; Martínez Piera, Eusebio; Andrada Gascón, Pedro
Abstract: 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&#xD;
savings in electric motors, LCA-based environmental impact assessment should be performed when different motors are being evaluated for a given industrial application.</description>

Authors: Andrada Gascón, Pedro; Blanqué Molina, Balduino; Perat Benavides, Josep Ignasi; Torrent Burgués, Marcel; Martínez Piera, Eusebio; Sánchez López, José Antonio
Abstract: A current-controlled switched reluctance motor drive for a variable speed applications with efficiency optimization is presented. Firing angles are computed online, the turn-on is calculated by means of the rule of Bose, and the tur-off is calculated using the general theory of the optimal turn-off angle proposed by Gribble. In steady state operation, the initial selection of firing angles is fine-tuned by means of an algorithm that minimizes the input power of the drive. An efficiency and electrical energy consumption comparison with a commercial vector-controlled induction motor drive of the same size is also included. Experimental results show that the proposed switched reluctance motor drive is a good choice for applications that require slow varying loads and energy savings.</description>

Abstract: 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.&#xD;
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&#xD;
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&#xD;
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&#xD;
results: output power and efficiency.&#xD;
Results and discussion The procedure was applied to two 1.5 kW induction motors of different efficiency (according&#xD;
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.</description>

      <description>Title: Method for estimating core losses in switched reluctance motors
Authors: Torrent Burgués, Marcel; Andrada Gascón, Pedro; Blanqué Molina, Balduino; Martínez Piera, Eusebio; Perat Benavides, Josep Ignasi; Sánchez López, José Antonio
Abstract: The prediction of switched reluctance motor (SRM) performance requires knowledge of core losses.&#xD;
However, the calculation of iron losses in SRM is especially complex first because the flux waveforms are&#xD;
nonsinusoidal and different parts of the magnetic circuit have different waveforms and second because they&#xD;
are conditioned by the type of control used. This study proposes an analytical method for calculating core&#xD;
losses that comprises simulation of the SRM using finite element analysis to determine the magnetization&#xD;
curves, and SRM modeling, which enables transient simulations with the associated electronic power&#xD;
converter run under different control strategies. The flux density waveforms in the different parts of the SRM&#xD;
are derived from the flux density waveform of the stator pole that is obtained from the transient simulation.&#xD;
The specific core losses (in W/kg) are separated into three parts (hysteresis losses, classical eddy current&#xD;
losses and excess losses) and calculated using the waveforms and time derivatives of the local flux density.&#xD;
The core losses for each part of the SRM’s magnetic circuit can be estimated using the calculated values for&#xD;
specific hysteresis losses, specific classical eddy current losses and specific excess losses for each zone.&#xD;
Adding these individual losses yields the total core losses. The method was applied to three-phase 6/4 SRM,&#xD;
and the calculated results were compared with experimentally obtained measurements.</description>

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

      <description>Title: Centrales electricas minihidraulicas: aplicacion en una zona rural subdesarrollada
Authors: Castellano, Jaime; Torrent Burgués, Marcel
Abstract: La implementación de microcentrales hidroeléctricas en zonas subdesarrolladas permite acceder a la&#xD;
energía eléctrica a comunidades rurales, cuando las dificultades para disponer del suministro a partir&#xD;
de las líneas eléctricas de transporte son insalvables por motivos de aislamiento o de coste&#xD;
económico. Previo análisis general de estas microcentrales, presentaremos los resultados más&#xD;
relevantes en un estudio práctico para la posible implementación de una microcentral en Perú,&#xD;
concretamente en el pueblo de Chambamontera, provincia de Jaén.&#xD;
El estudio realizado ha tenido la cooperación del organismo de colaboración técnica internacional&#xD;
llamado ITDG-Perú, que ha proporcionado información acerca de la localización geográfica para la&#xD;
microcentral. Aún así, debido a las dificultades para disponer de datos suficientes sobre el terreno&#xD;
donde se debería construir la microcentral, en el estudio no se han determinado los componentes&#xD;
que conciernen a la obra civil. Aún así se ha descrito, en parte, los componentes y las tecnologías&#xD;
más apropiadas para la microcentral, centrándose el estudio principalmente en la selección de los&#xD;
componentes eléctricos, como son la turbina hidráulica, el generador y el transformador. Además, se&#xD;
propone utilizar un método de gestión para pequeños sistemas eléctricos aislados para analizar la&#xD;
posible viabilidad económica.&#xD;
Los resultados presentados forman parte del proyecto final de carrera realizado por Jaime Castellano&#xD;
en la EPSEVG y tutorizado por Marcel Torrent del Departament d’Enginyeria Elèctrica de la UPC.</description>

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