摘要：
Sensorless position estimation based on signal-injection methods always requires a resistance- or inductance-based anisotropy. Therefore, a short-circuited electrical winding can be attached on the rotor. As will be derived in this paper, this method leads to both a resistance-and inductance-based saliency. By an experimental test setup, both saliencies are analyzed and compared towards their accuracy and frequency-dependence. Thereby, for the resistance-based saliency a characteristic behavior is found that can be explained by the interaction between the rotor winding and the eddy current effect.
