Abstract :
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. This paper proposes a simplified machine model by which the influence of one or more short-circuited rotor windings can be calculated and optimized with little effort. Simulations for the optimized rotor winding configurations are presented and compared to measurement results from an experimental machine.
