AC drive with permanent magnet synchronous motor and sensorless control

In the paper there are presented results of the sensorless control of AC drive with the permanent magnet synchronous motor. The method is based on the rotor magnetic flux components estimation. Practical realization was made by the microcomputer control system with the digital signal processor TMS320F2812. The graphical visualization of the electrical controlled drive was made by the software Lab View. The measured results of proposed laboratory stand with applied vector control and sensorless vector control were shown at the conclusion.
