This paper presents an improved physical phase variable model for electric drive simulations of permanent magnet machines. Emphasis is put on the accuracy of the mechanical behavior of the machine model and this makes the improved model suitable for noise and vibration investigations. Furthermore, the data storage scheme and interpolation method for the look up tables are revised and a memory and time efficient approach is suggested. This makes the new model also applicable for use in real time applications (e.g. drive controllers). Several comparisons of transient simulations between a finite element model and the model presented in this work illustrate the advantages of this method.
