Abstract: In submitting this article the writer wishes to disclaim any intention of making a contribution to the theory of a subject so thoroughly studied as the circle diagram of polyphase induction ...

The result is a circle diagram practically identical with that derived by Branson (A.I. E. E. Proceedings, June, 1912) from comparison of the two-phase and single-phase induction motors, except that ...

circle_star.py draws the circle diagram of a star connected 3-ph induction motor and calculates it various paramters such as operating point slip, stator current, rotor current, power factors, output ...
