A method of starting an open-loop vector control the method comprising the , steps of determining a stator inductance model of a synchronous machine measuring (2) the stator inductance of the synchronous machine in a plurality of directions. The method further comprises the steps of arranging (6) the measured stator inductances in the determined stator inductance model so as to form model parameters giving the minimum error checking (11) the polarity of , rotor magnetization in order to verify the direction thereof initializing , (14) flux linkages of the open-loop vector control according to the formed model parameters and the direction of the rotor magnetization and starting , the …

Why it's free to use
- Filed May 18, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 18, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 18, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
