low frequency electromagnetic modeling
There is an other Program which is also from Ansoft : RMxprt™.
RMxprt, our motor-design software, allows users to enter motor specifications, such as operating source, rotor, stator, lamination geometry, winding configuration, and materials, and automatically generates a cross-section of the motor. Design engineers can use closed-form analytical methods to calculate motor performance, reducing computation time to only seconds. Performance output includes waveforms of current, torque, speed, flux densities, input power, stator current, power factor, output power, and efficiency. The designer can change any input parameter to see how it affects the output performance. This data allows the user to determine performance trends and to decide which design concept is most likely to satisfy specifications. Once the engineer is satisfied with the design, RMxprt will automatically output the geometric model directly to Maxwell®, Ansoft's powerful finite-element software, to refine performance parameters and to increase the accuracy of the performance predictions.
Maxwell 2D includes a powerful, nonlinear, transient feature that is ideal for detailed motor analysis where combined electric circuit/magnetic field/motion calculations are required for accurate performance predictions. Using the model created by RMxprt, Maxwell accurately predicts essential engineering quantities, such as various currents and induced voltages, flux linkage, torque, speed, position, and power loss. Engineers may use the integrated signal-processing calculator to determine RMS or average value computations, curve fitting, and harmonics analysis.
