Polyphase induction motor pdf
WebThe polyphase induction motor invented by Nikola Tesla in 1886 had been developed by 1895 virtually into its present squirrel-cage form. The slip-ring induction motor was developed a short time later. Because of its simplicity and cheapness, the 3-phase squirrel-cage induction motor is now by far the most common type of motor in use for driving ... http://educypedia.karadimov.info/library/motorfunds.pdf
