The developed nonlinear permanent magnet synchronous machine (PMSM) model established a virtual model to simulate and assess the sensorless drive schemes for PMSMs avoiding the experimental trial and error method. In this paper, three sensorless PMSM drive schemes are investigated and compared, which are all based on the high frequency signal injection. The nonlinear PMSM machine model is employed...
This paper presents modeling, characterization and control of SPMSM under loaded conditions i.e. saturation. Determining the rotor flux position of PMAC machines under no-load is relatively trivial since it is directly related to the rotor position. However under loaded condition, saturation in particular, the flux is comprised of two components: one due to the rotor magnets and the other due to the...
This paper presents modeling, characterization and control of SPMSM under loaded conditions e.g. saturation. Determining the rotor flux position of PMAC machines under no-load is simpler since it flux and rotor position coincide. However under load condition, and in the presence of saturation in particular, the flux is comprised of two components: one due to the rotor magnets and the other due to...
