In this paper the static (flux linkage and torque) and steady state characteristics (speed, current and torque) of the switched reluctance motor (SRM) is investigated for four magnetic structures with various combinations of stator and rotor poles: 8/6 (basic configuration), 16/12 (`double poles' configuration), 16/14 and 16/18 (`toothed poles' configurations). The static characteristics are calculated for different rotor positions and excitation currents using numerical finite element method (FEM) for magnetostatic field analysis. Dynamic characteristics are calculated using specially developed software routines in package Matlab/Simulink. The purpose of this paper is to show the effects of the magnetic circuit structures on static and steady state characteristics of the SRM. Validation of the computational methods was carried out by comparing the calculated static and steady state characteristics with the ones measured on 8/6 SRM prototype.

This paper contains computing and measuring results of start-up, step load, braking and reversing performance of the induction motor. Computing of dynamic states was carried out using idealized mathematical model of the induction motor. The measuring of the dynamic characteristics of the induction motor was carried out with U/f power converter. The load of the induction motor is realized with eddy current brake. The results of computing and measuring are presented and compared.

This paper presents a procedure of determination of static characteristics of switched reluctance machines (SRMs). Calculations are realized for two SRM topologies including novel configuration with 8 stator and 14 rotor poles (SRM 8/14). This configuration is based on new pole design formula introduced recently. Flux linkage and static torque characteristics are calculated for different rotor positions and stator currents using two-dimensional finite element analysis (2D-FEA). Simulation results for new SRM 8/14 and conventional SRM 8/6 with the same number of phases and outer dimensions are presented and compared. This comparison shows that new configuration can have better torque density. Therefore, new design approach should be considered to make this type of machines a more attractive for high performance HEV's (Hybrid Electric Vehicle's) drives.

In this paper simulation for educational purpose in the field of electrical machines and electrical drives is discussed. Simulations and animations are bounded to materials of teaching practise in electrical engineering course and thus represent visualized book. In addition to animated programmed materials, each of the eight applications incorporated into the program include fundamental theory background of the matter shown in each application. Program includes many interesting examples which would have been mathematically tedious.

This paper gives on overview of the procedures of determination of static characteristics (flux linkage, magnetic coenergy and torque), steady state characteristics (current and torque) and dynamic characteristics (speed, current and torque) of switched reluctance motor. A two dimensional distribution of magnetic vector potential inside a motor is computed using finite element method. The flux linkage, magnetic coenergy and static torque are calculated for different rotor positions and stator currents. Steady-state and dynamic characteristics are calculated using specially developed software routines. All calculations are realized for switched reluctance motor with 8 stator and 6 rotor poles. Numerically obtained results are verified by experiment.
