This paper discusses the sensorless control capability of an outer rotor PMSM with two different concentrated stator coil winding configurations resulting in a single- and double-layer configuration at same machine geometry. As a key parameter the differential inductance in direct and quadrature axis over current load is measured and compared. Furthermore the steady state short circuit current is calculated analytically and measured.
