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 scathing, describing it pithily as a "weakly futuristic industrial fantasy which the author would probably claim to be about lack of communication. Bored audiences might have a similar view". Johnny Marr has stated in interviews that one of the main impetuses for his leaving The Smiths was Morrisey's insistence on covering the titular theme song to this movie. There is a famous quote published in a 1992 issue of "Record Collector" where Marr disdainfully said "'Work Is A Four Letter Word' I hated. That was the last straw, really. I didn't form a group to perform Cilla Black songs. That
