Yadda aiki na madori mai AC yana gina karamin kwai a lokacin da ya yi aiki a cikin karamin kwai na AC

Mai AC Motor ba wani wurare da aka fadada don gina kuli, amma don haɗa kuli zuwa energy na mechanical. Amma zan iya canza AC motors zuwa generators ta hanyar tushen abubuwa uku don gina kuli. Wannan fasahar zai iya a nufin da "generation mode" ko kuma "generator mode".

Fasahar AC motor a matsayin generator

Idan an yi amfani da AC motor a matsayin generator, yadda ya yi shi zai iya bayyana haka:

• Energy na mechanical na input: Don AC motor ya yi aiki a matsayin generator, ana bukatar energy na mechanical (wato alama, ruwan, steam, etc.) don kawo rotor na motor. Wannan energy na mechanical na input zai iya kawo rotor na motor zuwa rotation.

• Electromagnetic induction: Idan rotor na motor ya faru, yana da shi wuri magnetic field na stator windings na motor. Daga cikin Faraday's law of electromagnetic induction, wannan magnetic field na baka yana haɗa electromotive force (EMF) a winding, wanda ke gina electric current.

• Current output: Idan stator winding na motor ya sama da load, induced current zai ƙare a kan load, don haka ya samu output na electrical energy. A wannan lokaci, AC motor ya zama generator.

Yadda ake yi aiki

• Na biyu: Rotor na AC motor ya kawo da energy na mechanical uku kuma ya faru.

• Babbar dukkan magnetic field: Rotation na rotor yana da shi babban magnetic field na uku.

• Electromagnetic induction: Babban magnetic field yana haɗa induced electromotive force a stator winding.

• Kare current: Induced electromotive force yana kara current zuwa stator winding.

• Output na electrical energy: Ta hanyar load connection, electrical energy ta ƙare zuwa external circuit.

Takamawa da ake amfani da shi

• Regenerative Braking: A cikin electric vehicle ko subway train, idan mai haihuwa ya ƙara, motor zai iya zama generator wanda ke haɗa kinetic energy na haihuwar zuwa electricity kuma yana baka shi zuwa grid ko kuma ya sauka don amfani da shi a baya.

• Wind power generation: Wind turbines sun amfani da permanent magnet synchronous motors ko induction motors, kuma wind yana kawo blades zuwa rotation, wanda ke kawo rotor na motor zuwa rotation kuma gina electrical energy.

• Hydroelectric power: Turbine yana kawo rotor na motor zuwa rotation kuma gina electrical energy.

• Thermal power generation: Steam turbine ko wani ƙarin device na thermal energy conversion yana kawo rotor na motor zuwa rotation kuma gina electrical energy.

Key technology

• Control strategy: Yana bukata a kunna control strategy masu inganci don haɗa cewa motor ya yi aiki da dace a generator mode kuma ya zama maza maka suka haɗa energy na mechanical zuwa electrical energy.

• Inverter technology: A wasu lokutan, yana bukata a amfani da inverter don haɗa alternating current da ake gina zuwa alternating current da za su iya amfani a kan grid.

• Energy management and storage: Don wasu takamawa kamar regenerative braking, yana bukata a kunna energy management and storage systems don haɗa kula electricity da ake gina.

Gajarta

AC motor zai iya zama generator a lokutan da ya fi karfi, kuma rotor zai iya kawo da energy na mechanical uku zuwa rotation kuma gina electrical energy ta hanyar principle na electromagnetic induction. Wannan conversion yana da muhimmanci a wasu takamawa, musamman inda an bukata a ciwo energy ko kuma haɗa energy na mechanical zuwa electricity. Ta hanyar control da ƙarin technology, zai iya haɗa energy conversion da dace kuma zai iya taimaka wa ƙarin da suka haɗa efficiency na system.
