Kinannan Karamin Daidaito
Majiya na mota mai karamin kashi yana aiki da zama shi ne karamin kashi zuwa karamin kungiyar. Akwai uku na mota mai karamin kashi.
Mota mai Karamin Kashi Da Tsakiyar DC.
Mota mai Induction.
Mota mai Synchronous.
Duk waɗannan motoci sun yi aiki cewa kamar haka. Aiki na mota mai karamin kashi yana neman da aikin tsawonsa na karamin kashi da karamin kungiyar.
Ta haka za a iya magana game da sauran aikin mota mai karamin kashi bako-bako don samun fahimta mafi yawan bayani.
Aiki na Mota mai Karamin Kashi Da Tsakiyar DC
Sauran aikin mota mai karamin kashi da tsakiyar DC yana neman da aikin tsawon sauransu na Fleming Left Hand. A cikin mota mai karamin kashi da tsakiyar DC na biyu, ana sanya armature a kan abubuwan magana. Idan ana sanya armature winding ta hanyar malam karamin kashi na gaba, zai faru karshen karamin kashi har zuwa armature conductors. Saboda ake kara karshen karamin kashi a kan abubuwan magana, za su tattara kyau wadanda ke taimakawa zuwa armature. Idan ake faɗa armature conductors a kan N poles na field magnet, suka faru karshen karamin kashi a kan ƙarshe (crosses) kuma wadanda a kan S poles suka faru karshen karamin kashi a kan ƙarfi (dots). Daga binciken tsawonsa na Fleming’s Left hand Rule, zai iya tabbatar da haguji F, wadanda suka samu armature conductors a kan N poles da kuma haguji wadanda suka samu conductors a kan S-poles. Ana samu cewa a baya daban-daban haguji wadanda suka samu conductors suka haifar da armature.
Karin, saboda wannan rotation, conductors a kan N-poles suka zama a kan S-pole da conductors a kan S-poles suka zama a kan N-pole. A lokacin da conductors suka zama a kan N-poles zuwa S-pole da S-poles zuwa N-pole, ya kamata a kan tsayi da karamin kashi ta hanyar commutator.
Saboda wannan tsayi na karamin kashi, duk conductors wadanda suka zama a kan N-poles suka faru karshen karamin kashi a kan ƙarshe da duk conductors wadanda suka zama a kan S-poles suka faru karshen karamin kashi a kan ƙarfi kamar yadda aka nuna a takardun. Saboda haka, duk conductor wadanda suka zama a kan N-pole suka samu haguji a kan haguji daidai da kuma wadanda suka zama a kan S-poles suka samu haguji a kan haguji daidai. Wannan al'amari yana taimakawa zuwa torque mai tsayi da karamin kungiyar.
Aiki na Mota mai Induction
Aiki na mota mai karamin kashi a cikin mota mai induction yana bambanta da mota mai karamin kashi da tsakiyar DC. A cikin mota mai induction da phase ta kafuwar, idan ana sanya supply ta kafuwar zuwa stator winding, zai faru magnetic field mai pulsating kuma a cikin mota mai induction da phase ta uku, idan ana sanya supply ta uku zuwa stator winding ta uku, zai faru rotating magnetic field. Rotor na mota mai induction yana iya zama wound type ko squirrel cage type. Ba sai dai turancinsu rotor, conductors a kan ita suka fi sanya a kan ƙarshen da suka fi sanya. Saboda rotating magnetic field, flux zai faru a kan air gap daga rotor zuwa stator, zai faru a kan surface na rotor kuma zai faru a kan rotor conductors.
Saboda haka, a cikin Faraday’s law of electromagnetic induction, zai faru current mai induced a kan closed rotor conductors. Yadda ake faru current mai induced yana neman da rate of change of flux linkage da zaman. Karin, wannan rate of change of flux linkage yana neman da relative speed daga rotor zuwa rotating magnetic field. A cikin Lenz law, rotor zai tattauna a kammala babu kaɗan da take faru current a kan ita. Saboda haka, rotor zai tattauna da ya yi aiki da ya haifar da speed na rotating magnetic field don kammala relative speed daga rotor zuwa rotating magnetic field.

Aiki na Mota mai Synchronous
A cikin mota mai synchronous, idan ana sanya supply ta uku zuwa stator winding, zai faru rotating magnetic field wadanda yake faru a kan synchronous speed. Idan ake sanya electromagnet a kan wannan rotating magnetic field, yana haifar da rotating magnetic field kuma zai faru a kan synchronous speed.
Bayanin: Rabeta asalin, babban rubutu za'a iya buga, idandandan da take haifar za'a karin tsari.
