Kugwiritsa ntchitobrakeeresistorsmu zida za crane ndizofunikira kuti makina azigwira bwino ntchito.Njira yogwirira ntchito ya zida zonyamulira mu crane ndi: mota imagwira ntchito yopangira mphamvu poyenda pansi, ndipo mota imagwira ntchito posunthira mmwamba.Ngati palibe chopinga cha braking chikuwonjezedwa, magetsi opangidwa ndi injini amatha kuchitapo kanthu mwachindunji pa module ya inverter, ndikuwononga pafupipafupi gawoli.
Panthawi yochepetsera ma mota, inertia ya zida zambiri zithatembenukainjini kukhala jenereta, kuchititsa injini kupereka mphamvu kwa inverter mbali ina.Izi zitha kuyambitsa alamu yochulukirapo mu inverter.Pofuna kuthetsa vutoli, njira yowonjezera mphamvu yotsutsa (moyenera kuchepetsa mtengo wotsutsa) ingagwiritsidwe ntchito kumasula mphamvu zowonjezera.Kuphatikiza apo, zopinga zina za ma brake zimatha kupereka mphamvu zosinthira ku loop yamagetsi, yomwe imakhala yothandiza kwambiri pamakina osinthika omwe ali ndi mabasi wamba a DC ndikuthandizira kupulumutsa mphamvu.
Thebrakeewotsutsaimagwira ntchito yofunika kwambiri poletsa kuchulukira kwamagetsi kwa ma frequency converter pakutsika, kufupikitsa mtunda wochepetsera, ndikuwongolera magwiridwe antchito a zida zonyamulira.Ngakhale mabuleki omangidwira mkati mwagalimoto amagwiritsidwa ntchito kwambiri poyimitsa magalimoto omaliza, siwothandiza pakuchepetsa mabuleki.Apa ndipamene mabuleki olimbana nawo amayamba kusewera chifukwa amangokhudza mota panthawi yocheperako ndipo sizikhala ndi vuto injini ikayimitsidwa.Kuti injini isasunthike pansi pa katundu wotheka, mabuleki ayenera kugwiritsidwa ntchito.
Pankhani ya mtundu wa ma brake resistors omwe amagwiritsidwa ntchito ponyamula zida, ma aluminiyamu oletsa ma aluminium ndi ma ripple resistors nthawi zambiri amagwiritsidwa ntchito kuyambitsa katundu.Izi zoletsa ma braking zitha kuyikidwanso pamwamba pa wina ndi mzake, koma chisamaliro chapadera chiyenera kuperekedwa ku chitetezo ndi kukhazikitsa koyenera.Ngati chiwerengero cha resistors kuposa 4, iwo ayenera kuikidwa pa zitsulo chimango chapadera pamene kukhala mtunda wa 80mm pakati moyandikana wa magulu awiri resistors.Kuonjezera apo, chishango cha kutentha chikhoza kuikidwa pakati kuti chitetezedwe chowonjezera.Ndikofunikira kuwonetsetsa kuti zomangirazo zimakhazikika kuti ziteteze ngozi kapena kugwedezeka kwamagetsi kwa ogwira ntchito panthawi yoyika.
Mwachidule, kagwiritsidwe ntchito ka ma brake resistors mu zida za crane ndikofunikira kuti muzitha kuyendetsa kutulutsa mphamvu pakutsika, kupewa kuwonongeka kwa ma frequency converter, ndikuwongolera magwiridwe antchito ndi chitetezo chonse.Kuyika koyenera ndikumvetsetsa ntchito ya braking resistor ndikofunikira pakugwira ntchito bwino kwa makina a crane.
