The diagnostics of single-phase capacitor induction motors by the level of external magnetic field, with allowance for technological and operational factors

The results of analysis of high-speed rates of birdcages of electric drives and tensioning between interstand spaces of continuous subgroup of roughing mill group of mill 2000 of Joint Stock Company "MISW" are presented. It is shown that in the existing system of speed coordination the rolling schedule with the tensioning close to the zero is not ensured. The algorithm of the coordination of speeds in the course of rolling application of which ensures the raise of accuracy of maintenance of the set tensioning is proposed.
