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
Work Is a Four-Letter Word Work Is a Four-Letter Word Work Is a Four-Letter Word (also known as Work Is a 4-Letter Word) is a 1968 British satirical comedy film starring David Warner and Cilla Black, in her only acting role in a cinematic film.
