| Abstract |
The paper deals with authors' experience in designing and testing of a motor-inverter system for a new generation of high speed metal rolling mill stand. The engineering aspects related to the complex application requirements, the IGBT technology for the power converter, the electromagnetic design, bearing selection, cooling, ventilation system and insulation technique for the induction motor are covered. An extensive system testing is described, giving emphasis on the comparison between PWM and pure sine-wave power supplied motor behaviour. Other similar applications are also described. |
