Ama-rotor motors amanxeba e-AC zingamandla aguquguqukayo ezinhlelweni zokusebenza zezimboni, ezinikeza ukulawula okukhethekile phezu kwejubane netorque. Ukuqonda indlela yokuphatha isivinini sabo ngempumelelo kubalulekile ekuthuthukiseni ukusebenza nokusebenza kahle kwamandla. Lo mhlahlandlela obanzi uhlola ubunkimbinkimbi bokulawula isivinini se-AC isilonda se-rotor motor, uhlinzeka ngemininingwane ebalulekile konjiniyela, ochwepheshe, nezingcweti zemboni.
Izindlela Eziyinhloko Zokulawula Isivinini Se-Rotor Motor
Ukulawula isivinini se- Injini ye-rotor enenxeba ye-AC kuhilela amasu amaningana ayinkimbinkimbi, ngayinye inezinzuzo zayo kanye nokusebenza kwayo. Ake sihlole izindlela eziphumelela kakhulu:
1. I-Rotor Resistance Control
Le ndlela yendabuko ihilela ukwengeza ukumelana kwangaphandle kumjikelezo we-rotor ngokusebenzisa izindandatho ze-slip. Ngokulungisa lokhu kumelana, ungashintsha izici ze-torque yemoto. Le ndlela iwusizo kakhulu ezinhlelweni ezidinga i-torque yokuqala ephezulu kanye nokusheshisa okushelelayo.
2. Ukulawulwa kwamandla kagesi
Ukushintsha i-voltage ehlinzekwa kuma-windings e-stator kungalawula ngempumelelo isivinini semoto.
