WebConstruction of Circle Diagram - Induction Motor 1. Introduction: A circle diagram is the graphical representation of the performance of an electrical machine drawn in terms of the locus of the machine's input voltage and current. It can be drawn for alternators, synchronous motors, transformers and induction motors. WebA three-phase synchronous motor has no starting torque. It has to be brought up to speed or as close to it as possible by some other means so that it can pull itself into synchronism. Once up to speed, the rotor field can be excited with direct current and the rotor is, in effect, then dragged around at the same speed as the three-phase stator ...
