Tesis doctoral de Jordi Garcia Amoros
Two electromagnetic analytical models have been developed in this study. These models have yielded the main magnetic and mechanical characteristics of the lsrm and have allowed its primary dimensions to be determined. A prototype was built based on these results and was examined by means of finite element and experimental tests, which corroborate the validity of the contributed analytic models. this study describes the status of art and classification of the linear actuators as well as the genesis of the lsrm from its rotating counterpart. Lsrm performance was simulated in a matlab/simulink simulation model, which allowed us to determine the influence of the position shot for the phase current on the average force and thus the optimal interval conduction phase current. chapter 2 deals with a new electromagnetic model obtained from simple analytical expressions which allow parameters to be obtained and analyzed at a reduced computational cost. The end-effects (fringe effects) are also studied by means of analytical expressions and finite elements. A correction method was developed for the purpose of quantifying the aforementioned effect on the linked flux versus current characteristic. chapter 3 investigates the influence of the geometric dimensions on the force and inductance profiles using the finite element method, and describes the geometric relations that optimize the average force. chapter 4 presents the study of the main losses of the lsrm, mainly iron and copper. Once losses were obtained, an analytical thermal model of lumped parameters was developed from which the thermal behavior was predicted. a systematic methodology for designing the lsrm is laid out in chapter 5. This methodology allowed us to obtain the main parameters (electric, magnetic, mechanic and geometric) from the given design specifications. The methodology was validated by finite elements. chapter 6 describes how the analytic models were validated through the construction and testing of a prototype. The experimental results validate the contributions made in this study.
