Abstract:

A resistance- or inductance-based saliency is needed as a prerequisite for signal-injection based encoderless position estimation methods. The differential quantities can be influenced by applying a short-circuited electrical winding on the rotor of an electrical machine. For a configuration that has been optimized in former research, 2D finite element method simulations are carried out. To be able to simulate the machine's behavior via stationary AC simulations, the frozen permeability method is used hereinafter. The advantages for the given application and the method itself will be presented. The results at no-load conditions will be compared to those gained by measurements. In summary, the simulation results at load conditions will be discussed.
