Ka mohlala, ho theoha ho fetang 10% ha khanyetso e lekantsoeng ha e bapisoa le tlhaloso ea fektheri ea pele e ka bontša ho chenchana ha nako e khutšoanyane, ha keketseho e kholo e ka bontša lithapo tse robehileng kapa likhokahano tse fokolang. Ho nahana ka mocheso ho ka senola libaka tse hotspots tsa lehae tse bakoang ke ho se sebetse hantle ha li-coil kapa mathata a mokhanni. Ho kenya ts'ebetsong mananeo a tlhahlobo ea nako le nako ho fokotsa nako e sa reroang ho litsamaiso tse ikemetseng.

Maxtech Fana ka Litharollo

Maxtech e fana ka mefuta e fapaneng ea li-motor tsa unipolar stepper, bakhanni le likhetho tsa cabling tse lumellanang le litlhoko tsa indasteri le OEM. Ho tloha ho compact NEMA 17 units to high-torque NEMA 34 solutions, mohala oa rona oa lihlahisoa o akaretsa maqhubu a mekhahlelo ho tloha ho 0.4 A ho ea ho 4.0 A le ho tšoara li-torque ho fihla ho 3.5 N·m. Lihlopha tsa boenjiniere li fumana lintlha tse qaqileng tsa torque-speed curves, data e futhumatsang, le litšoantšo tsa lithapo ho potlakisa moralo. Hore na o hloka beche ea mohlala kapa thepa e kholo - thepa e rekisoang ka bongata, Maxtech e sebetsa e le mofani oa thepa e le 'ngoe' me e kopanya likopano tse ikhethileng tse tsoang femeng ea rona, ho u thusa ho fihlela motsamao o nepahetseng, o phetoang ka litšenyehelo tse felletseng le ts'epo.
