Features of building multi-motor adjustable electric drives based on asynchronous valve cascades.

Abstract

In accordance with the classification given in the paper, possible schemes of multi-motor cascade electric drives (MECE) are considered, which provide joint and separate control of the speeds of production lines and units. Evaluation of MVSE systems with individual inverters made according to various schemes is shown. It is shown that from the point of view of reliability is a circuit with thyristors shutiruyuschimi common inverter.
