Circle diagram Circle diagram First conceived by A. Heyland in 1894 and B.A. Behrend in 1895, the circle diagram is the graphical representation of the performance of the electrical machine drawn in terms of the locus of the machine's input voltage and current. The circle diagram can be drawn for alternators, synchronous motors, transformers, induction motors. The Heyland diagram is an approximate representation of circle diagram applied to induction motors, which assumes that stator input voltage, rotor resistance and rotor reactance are constant and stator resistance and core loss are zero. Another common circle diagram form is as described in the two
A Letter to a Hindu newspaper, "Indian Opinion", in 1909. Mohandas Gandhi was stationed in South Africa at the time and just beginning his lifelong activist career. He then translated the letter himself, from the original English copy sent to India, into his native Gujarati.
