The wide application of anisochronous variable-frequency driver for machinery in all fields of national economy at present resulted in the unseen before complete block diagram for this type of the drive in the literary sources in the field of study of electric drive. Diagram 1. It is universal, as the parameters of winding of anisochronous motor are not taken into account. Diagram 2. The advantage is the accounting of the parameters of a specific anisochronous machine. In addition, the version with the PID loop of speed corresponds completely to the definition of the actual frequency transformers and provides high accuracy of development of the required speed diagram. The comparative disadvantage is small overshoots in the moment ...
