| Abstract: | The self-adaptive soft starting characteristics of a 7. 5 kW ordinary induction motor or 1. 5 kW conical motor can be achieved by connecting in the stator circuit a nonlinear resistor made of semiconducting material. For different load characteristics, the analysis and calculations have been carried out for both the constant-current and constant-torque starting and the results can be used for resistor design.The method proposed can now be applied in a starting system with reversible braking by phase change-over of the stator winding. |
