In this paper, an ldquoactive-mover-passive-statorrdquo structure of linear switched reluctance motor (LSRM) is proposed with DSP control implementation. The motor has the characteristics of simple and robust mechanical structure. The design improvement is discussed and further verified with finite element analysis (FEA). The DSP-based position control scheme is implemented and experimental results...
This paper studies the sensitivity of several geometrical parameters on the performance of a linear switched reluctance motor (LSRM). The analysis is made in two dimensions using the finite element method. The study shows the strong influence of the width of the stator pole (bp) and the width of the moving pole or translator pole (bs) on inductance and force profiles. The results of this study could...
The speed and thrust control strategy for a double sided linear switched reluctance motor (DSL-SRM) is elaborated in the paper, based on a simplified analytical model. The strategy is defined for different motor phase supply conditions and the dynamic characteristics are calculated via computer simulation for a sample motor, in order to sustain the theoretical results.
A linear and a rotational switched reluctance drive with a large airgap are developed and manufactured for a test track of autonomous railway vehicles. The motor design, a coupled model and the results of finite-element-simulations are presented, along with the test bed structure and measurements. The design and control objectives are to maximize the efficiency and to minimize the acoustic noise at...
A transverse flux tubular switched reluctance motor of a particular construction is presented. The traction force equations are obtained based on two simplified models and a sizing designing procedure for the motor is developed. A two dimensions finite element method (2D-FEM) analysis is performed in order to check the analytically calculated performance and a sample motor is designed and analyzed.
Based on radial basis function neuron network (RBFNN), the model of nonlinear radial force in switched reluctance motor(SRM) is constructed in this paper. Training samples for RBFNN are obtained from the calculation results of a prototype SRM(8/6) with finite element method(FEM). Training algorithm is a hybrid method combining nearest neighbor clustering with steepest gradient descent. The simulation...
Based on the analysis of the magnetic field, a new simplified radial force analytical model for switched reluctance motors is established in this paper, in which saturation and fringing flux are considered. Moreover, the radial force is predicted by using FEM, and the model is validated by its predictions against those of the finite element method (FEM). Furthermore, the relationships between the...
This paper reports on a micro linear stepping motor with an integrated magnetic guidance which is built up using micro fabrication techniques like sputtering, UV depth lithography and electroplating. The results of FEM simulations in order to design the motor and the necessary changes in the layout for the purpose of levitating the traveller without additional components are presented. Using the same...
