Sensorless Start-up and Control of Permanent Magnet Synchronous Motor with Long Tieback
TL;DR: In this paper, the authors investigated the start-up procedure of a permanent magnet synchronous motor operated by a variable frequency drive without position feedback via a long cable and transformers, and the results showed that the vector controller gave the best performance during load step tests due to its precise control of the rotor field.
