The rotor mutual inductancesThis handbook deals with the asynchronous machine in its close environment. It was born from a reflection on this electromagnetic converter whose integration in industrial environments takes a wide part. Previously this type of motor operated at fixed speed, from now on it has been integrated more and more in processes at variable speed. For this reason it seemed useful, or necessary, to write a handbook on the various aspects from the motor in itself, via the control and while finishing by the diagnosis aspect. Indeed, an asynchronous motor is used nowadays in industry where variation speed aISTEElectric machinery, InductionAutomatic controlElectric motors, SynchronousAutomatic controlElectric driving, Variable speedElectronic books.Electric machinery, InductionAutomatic control.Electric motors, SynchronousAutomatic control.Electric driving, Variable speed.621.3136621.4Razik Hubert969026MiAaPQMiAaPQMiAaPQBOOK9910141492403321Handbook of asynchronous machine with variable speed2201501UNINA01184nam0 22002891i 450 UON0015299920231205102930.23120020107d1990 |0itac50 bafreKP|||| 1||||ˆL'‰art de l'OperaRésultats des entretiens avec des écrivains et des artistes, du 4 au 6 septembre 1974PyongyangEditions en Langues Etrangeres1990157 p.18 cmLETTERATURA COREANASEC.
