Tsarin motar kofin da babu komai yana ratsa tsarin rotor na gargajiya na motar, ta amfani da rotor mara tushe, wanda aka fi sani da rotor kofin da babu komai. Sabon tsarin rotor yana kawar da asarar wutar lantarki da eddy current da core ya samar ke haifarwa gaba daya. To menene fa'idodin injinan kofin da babu komai fiye da na yau da kullun.injinan dc?
Menene fa'idodin injin kofi mai ƙura?
1. Yawan ƙarfi mai yawa
Yawan ƙarfi shine rabon ƙarfin fitarwa zuwa nauyi ko girma. Motar coil ta jan ƙarfe ƙarami ne, aiki mai kyau. Idan aka kwatanta da coil na gargajiya, coil ɗin induction na farantin jan ƙarfe ya fi sauƙi. Ba tare da lanƙwasawa da lanƙwasa takardar ƙarfe ta silicon ba, ana kawar da asarar eddy current da hysteresis da suka haifar. Asarar eddy current a yanayin coil na jan ƙarfe ƙarami ne kuma mai sauƙin sarrafawa, wanda ke inganta ingancin motar kuma yana tabbatar da mafi girman ƙarfin fitarwa da ƙarfi.
2. Inganci
Ingancin injin ya ta'allaka ne akan gaskiyar cewa na'urar jan ƙarfe ba ta da eddy current da asarar hysteresis da ke faruwa sakamakon naɗewa da lanƙwasa takardar ƙarfe ta silicon. Bugu da ƙari, juriyar ba ta da yawa, tana rage asarar jan ƙarfe.
3. Babu ƙarfin juyi
Yanayin nada farantin tagulla ba tare da takardar ƙarfe ta silicon mai tsagi ba, babu asarar hysteresis, babu tasirin ramin haƙori don rage gudu da canjin karfin juyi.
4. Babu tasirin rami
An yi na'urar jan ƙarfe da ƙarfen silicon ba tare da wani tsagi ba, wanda ke kawar da tasirin tsagi da hulɗar da ke tsakanin tsagi da maganadisu ke haifarwa. Na'urar tsari ne wanda ba shi da tsakiyar ƙarfe. Duk abubuwan ƙarfe ko dai suna juyawa tare (misali injin buroshi) ko kuma suna tsayawa (misali injin buroshi). Tasirin rami da ƙarfin juyi a bayyane yake babu su.
5. Babu ƙarfin radial tsakanin rotor da stator
Tunda babu ferrite core mai tsayawa, ba za a iya samun filin maganadisu na axial tsakanin rotor motor da stator motor ba. Wannan yana da matuƙar muhimmanci musamman a aikace-aikace masu mahimmanci. Saboda ƙarfin axial tsakanin rotor motor da stator motor, rotor motor ba shi da ƙarfi. Rage ƙarfin axial zai inganta amincin rotor motor.
6. Lanƙwasa mai santsi da ƙarancin hayaniya
Babu wani ferrite mai kauri, wanda ke rage jituwar nisan juyawa da ƙarfin lantarki na aiki. Saboda ba za a iya samun filin AC a cikin injin ba, babu wani hayaniya da AC ke haifarwa. Sai dai hayaniya daga birgima da guguwa da kuma girgiza daga siffofin raƙuman ruwa marasa sinusoidal.
7. Kyakkyawan tasirin watsa zafi
Na'urar solenoid ta tagulla a ciki da wajen saman sau da yawa tana da ruwa mai yawa, wanda ya fi na'urar rotor solenoid ta injin ramin da ke watsa zafi daga bututun zafi. Wayar siliki ta gargajiya da aka rufe ta an saka ta a cikin ramin ferrite core. Akwai ƙarancin guguwar saman a cikin na'urar electromagnetic. Don irin wannan ƙarfin, hanyar na'urar electromagnetic ta tagulla ta zafin motar ta fi ƙanƙanta.
