This contribution suggests an approach to determine the optimal design of a Permanent Magnet Synchronous Motor for a given application by calculating the effects of coil configuration switching, pole-changing and multi-phase windings. The impact on the torque-speed-characteristic of a motor is evaluated in a normalized parameter plane, enabling the designer to compare the influences by using criteria...
This paper presents a holistic approach to determine the effect of online reconfiguration of the motor winding of a synchronous permanent magnet motor resulting in switching the number of turns. The analysis is based on a parameter plane, which predicts the behavior of synchronous machine designs by using only two normalized parameters, the permanent magnet flux linkage and the ratio of the quadrature...
A holistic approach to determine the optimum number of phases m of an m-phase motor in combination with an m-leg inverter for electric vehicle applications is presented. The optimum offers a significant improvement of the torque and power by approximately 9.6% over the whole operating range in comparison to a 3-phase motor and therefore enhances the power and torque density without expanding the design...
Iron losses are an important issue in high speed switched reluctance motors. A tool chain for the analysis of iron losses is introduced where arbitrary control schemes can be applied and a two-dimensional local loss distribution can be derived. The results are compared to a conventional calculation where individual machine components of uniform flux distribution in either tangential or radial direction...
In high-quality education, topics concerning the behavior and control of electrical machines and power electronics have to be taught not only theoretically but also in a practical manner. Hard- and software tools are necessary to fulfil this obligation. Nevertheless, commercial systems partially lack of functionality or full accessibility to implement custom solutions, which is obligatory in the research...
