Ein schnelles und genaues Simulationsmodell für permanentmagneterregte Kommutatormotoren kleiner Leistung mit Zahnspulen unter Berücksichtigung nichtlinearer Eigenschaften

This thesis presents a virtual rapid analysis model (VRAM) replacing the conventional reduced order systems model for physical value calculation of permanent magnet DC brush motors. The newly developed rapid calculation method (RCM) computes the superposition of magnetomotive forces with the aid of look-up tables while taking into account magnetic circuit saturation. Dynamic coil (current, voltage, flux linkage) and motor values (current, voltage, speed and torque) are calculated quickly and with high accuracy (including brush arcing) by the VRAM. Nonlinear flux linkage and torque values are almost identical to validated 3D finite element analysis, therefore verifying the model’s accuracy. The VRAM can be used to optimize nonmagnetic parameters, determine torque curves or develop control algorithms. The VRAM’s relative calculation speed versus conventional methods is an inexpensive alternative for research and development.
