for Electric Drives Operating with Constant Torque M. V. Andrianov, V. I. Afonin, and R. V. Rodionov Abstract —The problems of how to choose a frequency converter for an electric drive operating with constant torque and with frequent start-up are examined. A mathematical model permitting us to estimate power inputs in the frequency converter is suggested. DOI: 10.3103/S1068371208050088 …
