1. Ụdị ụgbọ okporo ígwè na-ebufe ụgbọ ala eletrik
Ụgbọ okporo ígwè na-ebufe ụgbọ okporo ígwè bụ ụdị ngwá ọrụ eji eme ihe na njem. A na-ekewa ụdị moto ha ụzọ abụọ: moto DC na moto AC. DC Motors dị mfe ma dị mfe ijikwa ma na-ejikarị na ụgbọ okporo ígwè na-ebufe ụgbọ ala; Moto AC nwere uru na oriri ike na ikike ibu, ma ejirila ya mee ihe n'afọ ndị na-adịbeghị anya.
2. Ụkpụrụ na-arụ ọrụ nke DC Motors
Igwe ọkụ ụgbọ ala DC bụ ụdị akụrụngwa na-agbanwe ike eletrik ka ọ bụrụ ike igwe. Mgbe kpọmkwem ugbu a na-agafe na armature winding, armature winding na-atụgharị n'okpuru omume nke magnetik, na wires na armature winding ga-eme ka a kpalitere ikike na magnetik, nke na-eme ka ntụziaka nke armature winding ugbu a gbanwee, na-eme ka oghere magnetik na-atụgharị na armature. N'aka nke ọzọ, oghere magnetik na-atụgharị na-eme ka armature ahụ gbanwee, ma n'aka nke ọzọ, ọ na-emekọrịta ihe na oghere magnetik na-adịgide adịgide iji mee ka moto na-arụ ọrụ nke ọma.
Enwere ụzọ njikwa abụọ maka moto DC: njikwa voltaji na njikwa PWM. Njikwa voltaji ozugbo adịghị arụ ọrụ ma dabara adaba maka ọnọdụ ebe ọsọ na-adịghị agbanwe nke ukwuu; Njikwa PWM nwere ike nweta nguzozi n'etiti arụmọrụ dị elu na nnukwu ibu ibu. Ya mere, ụgbọ ala nnyefe ụgbọ ala eletrik na-ejikarị njikwa PWM na-ebugharị iji hụ na nguzozi n'etiti arụmọrụ na arụmọrụ.
3. Ụkpụrụ na-arụ ọrụ nke AC moto
moto AC bụ ngwaọrụ nke ọzọ na-ebugharị. Dika njiri mara nke ugbua ngbanwe nke uzo ato si di, ndi agha eletrịkị nọọrọ onwe ha ga-atụgharị akụkụ nke etiti (ie rotor) nke moto AC. Mgbe mmepụta ike na-agbalị ịdọrọ rotor, ọ ga-emepụta rotor ugbu a na stator winding, nke na-eme ka moto ahụ na-emepụta ihe dị iche iche nke oge, si otú ahụ na-emepụta ihe dị ukwuu ma na-ebugharị ụgbọ okporo ígwè eletrik na-agba ọsọ.
Enwere ike ijikwa moto AC site na njikwa vector na njikwa induction. Njikwa vector nwere ike nweta ọtụtụ torques mmepụta ma melite ngwangwa na ikike ibu nke moto; njikwa induction dabara adaba maka ọnọdụ dị ala, mana nwekwara njirimara nke mkpọtụ dị ala. N'ime ụgbọ ala eletrik na-ebufe ụgbọ oloko, n'ihi mkpa maka ibu dị elu, ike dị elu, obere mkpọtụ na njirimara ndị ọzọ, a na-ejikarị njikwa vector eme ihe iji nweta ọrụ dị mma na ntụkwasị obi.
