Circle diagram constant air-gap induction motor images shown here, where, The circle diagram is drawn using the data obtained from no load and either short circuit or, in case of machines, blocked rotor tests by fitting a half-circle in points O and A. Beyond the error inherent in the constant air-gap assumption, the circle diagram introduces errors due to rotor reactance and rotor resistance variations caused by magnetic saturation and rotor frequency over the range from no-load to operating speed. Steinmetz equivalent circuit Circle diagram First conceived by A. Heyland in 1894 and B.A. Behrend in 1895, the circle diagram is the
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
