Yimuphi umehluko phakathi kwamandla kagesi alinganisiwe kanye ne-torque phakathi kwama-motor anamandla afanayo?

Kufanele kuqashelwe ukuthi ijubaneinjini kagesiAmandla afanayo angahluka kakhulu kuye ngezimo zokusetshenziswa noma imishini esekelayo. Ngendlela yokubonisa, ama-motor angu-2P no-8P ku-i-ac motor kagesi yezimboniinejubane elihambisanayo elingu-3000 rpm kumoto enama-pole amabili, kuyilapho ijubane elihambisanayo lemoto engu-8P lingu-750 rpm kuphela. Inhloso yengxoxo yanamuhla ukuhlaziya ubudlelwano bosayizi bemingcele efanele yeimoto engenazo izigaba ezintathus enamandla afanayo kodwa izinombolo zezigxobo ezahlukene. I-voltage elinganisiwe kanye nemvamisa elinganisiwe yizimo zokuphakelwa kwamandla okusebenza okuvamile kwemoto. Ngokusekelwe kulezi zimo ezimbili, sihlaziya futhi sixoxe ngobudlelwano bosayizi bezinye izinhlaka.

Ubudlelwano bosayizi wamandla alinganiselwe: Sihlaziya ubudlelwano phakathi kwamandla okufaka kanye ne-voltage elinganiselwe, amandla alinganiselwe, ukusebenza kahle kanye ne-power factor ngokusekelwe kufomula P1=√3UIcosϕ.

Kufanele kuqashelwe ukuthi ukusebenza kahle kanye nesici samandla sama-motor anesivinini esiphansi kuncane kakhulu, okuholela ekutheni kube nomthamo omkhulu ohambisanayo.

Ubudlelwano phakathi kwe-torque elinganisiwe nosayizi wengxenye okukhulunywa ngayo bunjengoba bulandelayo: Ngokuhambisana nobudlelwano phakathi kwe-torque elinganisiwe namandla alinganisiwe emoto, T=9.55P/n, kungabonakala ukuthi njengoba ijubane lehla ngaphansi kwezimo ezifanayo zemoto yamandla, i-torque ehambisanayo iyanda ngobukhulu. I-torque ichazwa njengekhono lemoto yokudonsa umthwalo. Ama-motor anejubane eliphansi ahlukaniswa ngekhono lawo lokuletha i-torque ephezulu ngejubane eliphansi. Ngokufanayo, ama-motor anejubane eliphezulu ahlukaniswa nge-torque ephansi kanye nejubane eliphezulu.

Kusukela kulolu lwazi, singaqinisekisa ukuthi kuma-motor anamandla afanayo kodwa anezinombolo zezigxobo ezihlukene, ugesi olinganiselwe we-motor enesivinini esiphansi mkhulu kancane kunowe-motor enesivinini esikhulu. Kodwa-ke, kukhona ukungafani okuphawulekayo ku-torque elinganiselwe, okulingana ngokuphambene nesivinini. Lokhu kunikeza nokuqonda ukuthi kungani ububanzi bomgodi we-motor enesivinini esiphansi bukhulu kakhulu, futhi imininingwane yokuthwala ehambisanayo nayo inkulu.
