METHOD FOR CONTROLING FREQUENCE- STEERABLE INDUCTION ELECTROMOTOR

摘要

The method applies for regulable actuations of asynchronious engines. It improves a quick transition from one speed of revolution to another and improves the power parameters. The method: the optimum frequencies of the feeding pressure at motive and generation regimes for a series of discrete values of the engine's speed of revolution are assessed in advance. They encompass the entire scope of regulation. These values are recorded in the permanent memory, from where in the process of regulation this value - which is closest to the current frequency of revolution - has been read, while this very current frequency almost reaches the preset frequency of revolution. The value of the feeding pressure is formed through schematic means depending on the set optimum feeding frequency.
