Ngakhale njira zoyendetsera magalimoto pamsika zimakhazikitsidwa ndi ma Servo motors amagwiritsidwa ntchito kwambiri, koma nthawi zina, ubwino wa ma stepper motors ndiwambiri kuposa ma servo motors, kotero ndikofunikira kuti mainjiniya amagetsi amvetsetse ma stepper motors, m'nkhaniyi tikambirana mfundo ntchito, gulu ndi makhalidwe a stepper Motors mwatsatanetsatane.
Stepper motor ndi mtundu wa motor induction. Mfundo yake yogwirira ntchito ndikugwiritsa ntchito makina amagetsi kukonza dera la DC kuti lipereke mphamvu pogawana nthawi. Kutsatizana kwa magawo ambiri kumayendetsa panopa. Pogwiritsa ntchito pano kuti mupereke mphamvu ku stepper motor, stepper motor imatha kugwira ntchito bwino. Ndi kugawana nthawi magetsi kwa stepper motor.
Ngakhale ma stepper motors akhala akugwiritsidwa ntchito kwambiri, ma stepper motors sali ngati wambaDC motere,ndiAC motereamagwiritsidwa ntchito mwachizolowezi. Iyenera kugwiritsidwa ntchito ndi dongosolo ulamuliro wapangidwa iwiri mphete zimachitika chizindikiro, mphamvu pagalimoto dera, etc. Choncho, si kophweka ntchito bwino motors stepper. Zimaphatikizapo chidziwitso cha akatswiri ambiri monga makina, injini, zamagetsi ndi makompyuta.
Monga actuator, stepper motor ndi imodzi mwazinthu zofunika kwambiri zamakina ndipo imagwiritsidwa ntchito kwambiri pamakina osiyanasiyana owongolera makina.Ndi chitukuko cha ma microelectronics ndi ukadaulo wamakompyuta, kufunikira kwa ma stepper motors kukukulirakulira tsiku ndi tsiku, ndipo amagwiritsidwa ntchito m'magawo osiyanasiyana azachuma chadziko.
Ma motor stepping motors omwe amagwiritsidwa ntchito kwambiri ndi ma reactive stepping motors (VR), maginito stepping motors (PM), ma hybrid stepping motors (HB), ndi masitepe amodzi amodzi.
Permanent maginito stepper mota:
The okhazikika maginito poponda galimoto zambiri magawo awiri, makokedwe ndi voliyumu ndi zazing'ono, ndi makwerero ngodya zambiri 7.5 madigiri kapena 15 madigiri; chokhazikika cha maginito chopondapo chili ndi torque yayikulu.Kuchita kwamphamvu ndikwabwino, koma mbali yake ndi yayikulu.
Reactive stepper motors:
The reactive stepping motor nthawi zambiri imakhala ndi magawo atatu, omwe amatha kutulutsa torque yayikulu. Ngodya yopondapo nthawi zambiri imakhala madigiri 1.5, koma phokoso ndi kugwedezeka kumakhala kwakukulu kwambiri. Ma rotor magnetic routing a reactive stepping motor amapangidwa ndi zinthu zofewa za maginito. Pali ma windings amitundu yambiri omwe amagwiritsa ntchito kusintha kwa permeance kuti apange torque.
The reactive steping motor ili ndi mawonekedwe osavuta, mtengo wotsika wopanga, ngodya yaying'ono, koma osachita bwino.
Hybrid stepper motor:
Hybrid stepping motor imaphatikiza ubwino wa ma motors okhazikika komanso okhazikika a maginito. Ili ndi ngodya yaying'ono, kutulutsa kwakukulu komanso magwiridwe antchito abwino. Pakali pano ndiye injini yokwera kwambiri yokwera kwambiri. Amatchedwanso okhazikika maginito induction. Galimoto yolowera pang'onopang'ono imagawidwanso magawo awiri ndi magawo asanu: mbali ziwiri zopondapo ngodya ndi madigiri 1.8, ndipo mbali zisanu zopondapo nthawi zambiri zimakhala madigiri 0,72. Mtundu woterewu wa masitepe ndi womwe umagwiritsidwa ntchito kwambiri.
