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
Brain Age: Train Your Brain in Minutes a Day! to 120 as fast as they can without slurring the names of numbers. Word Memory gives the player a list of 30 four-letter words. The player is given two minutes to study the list and memorize as many words as possible. After this two minutes is up, the player must write down as many words as he or she can in three minutes. Another puzzle called Connect Maze gives players a randomly created group of circles, with letters and numbers in them. There is one circle for every letter in "A" through "M", as well as a circle for every
