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 Elise the band's 4Tour World Tour 2007–08. A promo version of the song features yet another longer unreleased mix, with phaser on Robert Smith's voice. An instrumental version on cassette is also known to exist. "A Letter to Elise" itself was revived by the band's new Smith/Gallup/Thompson/Cooper lineup in 2005 after being played sparingly, if ever, during the Smith/Gallup/Bamonte/Cooper/O'Donnell era. Like "The Big Hand", it was not played very often, and was usually a pleasant surprise to fans when it popped up in setlists. "A Letter to Elise" has been covered by Aaron Sprinkle, for his "Really Something EP", Blink-182, for
