| Abstract |
This paper proposes the combination of two sensorless control algorithms for the secure start-up andthe efficient operation of a remotely-controlled PMSM. V/ f control is applied during the start-up of themotor and vector control is used for operation at higher speeds. The investigated system consists of along step-out configuration with a cable and two transformers between the PMSM and its VSD. Thesystem is tested with simulations and with experiments on a lab model. The results demonstrate thatV/ f control can safely start the PMSM. The effect of the inertia of the rotating assembly, the load torqueand the initial rotor position on the start-up performance of the system is investigated and the successfultransition from V/ f control to vector control is demonstrated. |
