| Abstract: | A procedure for position-sensorless control of permanent magnet synchronous motors with surface mounted magnets is proposed, that is suitable to large traction drives with their restrictions like high inverter-utilisation and low switching frequency. Position and speed are obtained by an observer using a voltage and an inductance motor model together with test signal injection at low speed. Improve- ments of the basic estimation scheme are presented. The method has been tested successfully in the lab with a 28kW standard servomotor. |
