Електрически двигател: Разлика между версии

* През 1882 [[Никола Тесла]] открива принципите на [[алтернатор|въртящото магнитно поле]] и въвежда използването на въртящия момент за работа с машини. Той го използва, за да създаде един уникален двуфазен индукционен двигател през 1883&nbsp;г<ref name="TFI (now)">{{cite web|last=The Case Files: Nikola Tesla|title=Two-Phase Induction Motor|url=http://www.fi.edu/learn/case-files/tesla/motor.html|publisher=The Franklin Institute|accessdate=2 декември 2012}}</ref><ref name="Smil (2005)">{{Cite book|first=Vaclav|last= Smil|title=Creating the Twentieth Century:Technical Innovations of 1867&nbsp;– 1914 and Their Lasting Impact|url=http://books.google.com/books?id=ZANP8uYlu1cC&pg=PA76|year=2005|publisher=Oxford University Press|isbn=978-0-19-988341-7|page=76}}</ref><ref name="Froehlich (1998)">{{Cite book|first=Fritz E.|last= Froehlich|coauthors=Kent, Allen|title=The Froehlich/Kent Encyclopedia of Telecommunications: Volume 17&nbsp;– Television Technology|url=http://books.google.com/books?id=8j5bJ5OkGpgC&pg=PA37|accessdate=10 октомври 2012|date=1 декември 1998|publisher=CRC Press|isbn=978-0-8247-2915-8|pages=37–}}</ref><ref name="Drury">{{cite book|url=http://books.google.com/books?id=vDQHzeEmSfUC&pg=PR14&lpg=PR14&dq=tesla+Ferraris+induction&source=bl&ots=SLjNT7Ui97&sig=Mvp66d6LH3KWUxrjdVBvFpl-lbY&hl=en&sa=X&ei=eGx3UNCXKLCB0QHH1YFA&ved=0CEgQ6AEwBTgU#v=onepage&q=tesla%20Ferraris%20induction&f=false|first= Bill|last= Drury|title= Control Techniques Drives and Controls Handbook|page= page xiv|year=2001|publisher=Institution of Electrical Engineers|isbn=0-86296-793-4 <!--Bad checksum-->}}</ref><ref name="Langsdorf (1955)">{{cite book|last=Langsdork|first=Alexander Suss |title= Theory of Alternating-Current Machinery|year=1955|edition=2nd|page=245|url=http://books.google.ca/books/about/Theory_of_Alternating_Current_Machinery.html?id=zKVd780XHGcC&redir_esc=y|publisher=Tata McGraw-Hill|isbn=0-07-099423-4}}</ref><ref name="EAE (1977)">{{cite book|title=The Encyclopedia Americana| Volume 19|year= 1977|page=518}}</ref>

През същата година [[Никола Тесла]] патентова двуфазна система за захранване на няколко вида двигатели на променлив ток, разработени от него. Поради големите възможности на променливия ток за отдалечено токозахранване, [[Джордж Уестингхаус]] незабавно купува патентите на Тесла и те са внедрени в производство.<ref name="Neidhofer (2007)">{{cite journal|last=Neidhöfer|first=Gerhard|title=Early Three-Phase Power (History)|journal=IEEE Power and Energy Magazine|volume=5|issue=5|pages=88&nbsp;– 100|doi=10.1109/MPE.2007.904752|url=http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=4295047&contentType=Journals+%26+Magazines&queryText%3Dearly+three-phase+power+winner+in+the+development+of+polyphase}}</ref><ref name="Pansini (1989)">{{cite book |title= Basic of Electric Motors |last= Pansini |first= Anthony J. |year=1989 |publisher=Pennwell Publishing Company |isbn=0-13-060070-9 |page=45 |url=http://books.google.it/books?id=CxQdC6xPFSwC&pg=PA45&lpg=PA45&dq=GALILEO+FERRARIS+AC+MOTOR+INVENTION&source=web&ots=jjeS-hcv2T&sig=cYbNfNNeVwvMIhR-JCP8uReedRU&hl=it&sa=X&oi=book_result&resnum=1&ct=result#v=onepage&q&f=false}}</ref><ref name="Alger (1976)"/><ref name="Alger (1976)">{{cite journal|last=Alger|first=P.L.|coauthors=Arnold, R.E.|title=The History of Induction Motors in America|journal=Proceedings of the IEEE|year=1976|volume=64|issue=9|pages=1380&nbsp;– 1383|doi=10.1109/PROC.1976.10329|accessdate=1 декември 2012}}</ref><ref name="Klooster (2009)">{{cite book|last=Klooster|first=John W.|title=Icons of Invention the Makers of the Modern World from Gutenberg to Gates.|publisher=ABC-CLIO|location=Santa Barbara|isbn=978-0-313-34744-3|url=http://books.google.com/books?id=WKuG-VIwID8C&pg=PA305&lpg=PA305&dq=tesla+hired+by+westinghouse&source=bl&ots=KDI0aTz0EK&sig=oct2jnPyWkQ3qvUR-JmstK9F0FI&hl=en&sa=X&ei=jRwxUKK3LtS80QHjxoGYAg&sqi=2&ved=0CEEQ6AEwAw#v=onepage&q=tesla%20hired%20by%20westinghouse&f=false|date=30 юли 2009 |[page=305|accessdate=10 септември 2012}}</ref><ref name="Klooster (2009)"/><ref name="Day (1996)">{{cite book|last=Day|first=Lance |title=Biographical Dictionary of the History of Technology|year=1996|publisher=Routledge|location=London|isbn=0-203-02829-5|coauthors=McNeil, Ian; (Editors)|page=1204|accessdate=2 декември 2012|url=http://books.google.ca/books?id=n--ivouMng8C&pg=PA1204&lpg=PA1204&dq=tesla+induction+motor+patent&source=bl&ots=CwZdCXFBMs&sig=yHtXcB6ukl3dO26c73h884URzsI&hl=en&sa=X&ei=1VpOUKCPAaLv0gGb14HwAw&redir_esc=y#v=onepage&q=tesla%20induction%20motor%20patent&f=false}}</ref><ref name="Froehlich (1992)">{{cite book|last=Froehlich|first=Fritz E.
