COUPLED SIMULINK-SIMPLORER MODEL OF A MODULAR HYBRID LINEAR STEPPER MOTOR Szabó Loránd, Dobai

The modular hybrid linear stepper motor in discussion has improved performances due to its novel construction. This linear motor can be one of the best choices for industrial applications where fast and accurate linear motions under heavy loads are required. In this paper a coupled simulation program of this motor will be presented. The basic part of the model is built up in SIMULINK. The forces of the motor are not computed at each time step. They are taken from two look-up tables containing the static characteristics of the forces, computed using MagNet 6.0 FEM-based magnetic field analysis program. The power converter's model was made in SIMPLORER, a widely used simulation program in the field of power electronics. The converter units were coupled into SIMULINK by the Sim2Sim link. This way all the parts of the model were implemented in the most suitable platform for each of them. The obtained results are in good accordance with the theoretical expectations and with the results of analytical computations. This means that the overall performances of the simulation program are quite good. Therefore the idea of coupling units built-up in different simulation platforms into a single simulation program could be also applied for simulating other types of electrical machines.
