However, because of the saliency characteristic of SynRM, LS-SynRM have a limited power factor. Therefore, to improve the efficiency and power factor of electric motors, we propose a line-start permanent magnet assistance synchronous reluctance motor (LS-PMA-SynRM) with permanent magnets inserted into LS-SynRM. IM and LS-SynRM are selected as reference models, whose performances are analyzed and compared with that of LS-PMA-SynRM using a finite element analysis. The performance of LS-PMA-SynRM is analyzed considering the position and length of its permanent magnet, as well as its manufacture. The final model of LS-PMA-SynRM is designed for improving the efficiency and power factor of electric motors compared with LS-SynRM. To verify the finite element analysis (FEA) result, the final model is manufactured, experiments are conducted, and the performance of LS-PMA-SynRM is verified.

  • The Reluctance Motor Springs Forth Dan Jones There Are Three Major Types of Reluctance Motors: All Three Reluctance Motors Are Non-Permanent Magnet, Brushless Motors
    TECHNICAL The Reluctance Motor Springs Forth Dan Jones There are three major types of reluctance motors: all three reluctance motors are non-permanent magnet, brushless motors. They are synchronous motors with a non-linear relationship between torque and current. The variable-reluctance step and switched-reluctance motors utilize the principle of magnetic attraction by inducing magnet poles within the soft-iron rotor, and by energizing a set of coils wound around stator teeth resident in the laminated stator. These two reluctance motors must be sequentially excited to achieve continuous, steady- state rotation. The design of all reluctance motors requires finite element analysis (FEA) software. History The first reluctance motor was invented in 1838 to propel a lo- comotive. The mechanical switches used for sequentially en- ergizing the windings available at that time could only ener- gize the motor at very slow speeds. This switched-reluctance motor would have to await fast-switching electronic devices (e.g., transistors, FETs, IGBTs) that would become available in the 1970s to drive these motors. The 1920s saw the development of variable-reluctance step motors in the U.K. for use in naval gun and navigation indica- tors. The emergence of the computer peripherals (printers, cash registers, and electronic typewriters) provided the ap- plication families for the thousands of variable-reluctance step motors in the 1970s and into the 1980s. The emergence of the solid state devices at that time pro- vided for the creation and control of the switched reluctance (SR) motor. It possesses the same motor configuration as the variable reluctance step motor, but with a completely differ- ent drive and control electronics strategy.

  • Dynamics Induced in Microparticles by Electromagnetic Fields
    DYNAMICS INDUCED IN MICROPARTICLES BY ELECTROMAGNETIC FIELDS A conceptual introduction to nanoelectromechanical systems Patricio Robles Escuela de Ingeniería Eléctrica, Pontificia Universidad Católica de Valparaíso, Chile Roberto Rojas Departamento de Física, Universidad Técnica Federico Santa María, Valparaíso, Chile Italo Chiarella Escuela de Ingeniería Eléctrica, Pontificia Universidad Católica de Valparaíso, Chile 1 PREFACE This is a review addressed to undergraduate students of electrical engineering and physics careers, and our aim is to present a pedagogical integration of some knowledge acquired in electromagnetism and electromechanical energy conversion courses, and to show how they can be used in actual technology applications, in particular for microscopic and nanoscopic systems. In general, the contents of electromagnetic courses looks rather abstract to students at an intermediate level of the electrical engineering career and its applications are hard to be appreciated by them. The course of electromechanical energy conversion provides to the students a good link with processes of electrical engineering but in our opinion it is necessary a book containing a better integration and correlation of topics learned in these courses, such as energy and momentum transfer between electromagnetic fields and movile devices, at a macroscopic and at a microscopic level. At a macroscopic scale, in general a good integration results in these courses for understanding how by means of variation in the energy stored in the magnetic field and interaction between rotating magnetic fields it is possible to produce mechanical or electric power for the operation of motors or generators, respectively. In general the programs of these courses give less emphasis on similar processes that are possible with the energy stored in the electric field as is the case, for example, of capacitors with movile plates or the interaction between electric polarized objects with rotating electric fields.

Based on the proposed optimization method, the efficiency and cogging torque characteristics of the PMSM can be improved. Abstract: In this study, a shape design optimization method is proposed to improve the efficiency of a 3 kW permanent magnet synchronous motor (PMSM) used in an electric compressor intended for use in an electric vehicle. The proposed method improves the efficiency performance of the electric compressor by improving the torque characteristics of the initial PMSM model. The dimensions of the rotor were set as the design variables and were chosen to maximize efficiency and reduce cogging torque. During the determination of the design points with conventional Latin hypercube design, the experimental points may be closely related to each other. Therefore, the optimal Latin hypercube design was used to optimally distribute the experimental points evenly and improve the space filling characteristics. The Kriging model was used as an interpolation model to predict the optimal values of the design variables.
