Determination of voltage at the terminals of an electric motor in a thyristor asynchronous electric drive.
Abstract
The features of measuring the voltage at the terminals of an asynchronous electric motor controlled by a thyristor voltage converter are considered. The significant effect of the electromotive force of rotation of the motor on the measurement accuracy of the output voltage of the converter is shown. An experimentally-calculated method for determining this voltage is proposed, the results of calculations confirmed experimentally are given. Il 3. Bibliogr .: 4 titles.
