Kona yakatenderedzwa yemota isina mutoro, ukuwo zvikamu zviviri zviri pedyo zvichifara
Mwero wemota yestepperkufamba-famba kunoramba kuchienderera mberi.
Torque yakanyanya iyo shaft inogona kutsungirira pasina kutenderera nguva dzose, ukuwo waya dze lead dzakabviswa.
Torque yepamusoro inomira yakasimba iyo shaft yemota yekutsikaKufara nemagetsi akayerwa kunogona kutsungirira pasina kutenderera kunogara kuripo.
Mapundu epamusoro anogona kutanga nemota ye stepper ine mutoro wakatarwa uye hapana desynchronizing.
Mwero wepamusoro wekurova kwemoyo unogona kusvika kune mota ine excited stepper inotyaira mutoro wakasiyana uye haugone kudzivirira kupatsanurwa kwesimba.
Torque yepamusoro iyo excited stepper motor inogona kutanga padanho rakati rekurova kwemoyo uye haichengetedze desynchronizing.
Torque yakanyanya iyo mota ye stepper inotyairwa zvichienderana nemamiriro ezvinhu akarairwa uye mwero wekurova kwemoyo wakati inogona kutsungirira uye haigone kuchengetedza desynchronizing.
Mhando yekurova kwemoyo inogona kutanga, kumisa kana kuremekedza mota ine mutoro unorayirwa nemutemo, uye haichengetedze kurova kwemoyo.
Voltage yepamusoro inoyerwa pachikamu chimwe nechimwe, kana ichitakura mubato wemota nekumhanya kwakafanana kwe1000 RPM.

Chopper constant current drive circuit rudzi rwedrive mode ine mashandiro ari nani uye inoshandiswa zvakanyanya parizvino. Pfungwa huru ndeyekuti current rating ye conductive phase winding inochengetwa zvisinei nekutimota yekutsikairi muchimiro chekuvharwa kana kuti iri kushanda mufrequency yakaderera kana yakakwira. Mufananidzo uri pazasi ndiwo dhayagiramu yedhiraivha yedhiraivha yechopper constant current drive, umo dunhu rimwe chete redhiraivha yephase drive rinoratidzwa, uye rimwe divi rakafanana. Kuvhurwa kwedhiraivha yephase kunodzorwa pamwe chete ne switching tube VT1 neVT2. Emitter yeVT2 yakabatana ne sampling resistance R, uye kudonha kwepressure padhiraivha kunoenderana ne current I yedhiraivha yephase.
Kana control pulse UI iri pavoltage yakakwira, machubhu ese eVT1 neVT2 anobatidzwa, uye simba reDC rinopa winding. Nekuda kwesimba re inductance yekumonera, voltage iri pa sampling resistance R inowedzera zvishoma nezvishoma. Kana kukosha kwevoltage yakapihwa Ua kwapfuura, comparator inoburitsa low level, zvekuti gate rinoburitsawo low level. VT1 inobviswa uye simba reDC rinobviswa. Kana voltage iri pa sampling resistance R iri pasi pevoltage yakapihwa Ua, comparator inoburitsa high level, uye gate rinoburitsawo high level, VT1 inobatidzwa zvakare, uye simba reDC rinotanga kupa simba kuwinding zvakare. Kazhinji, current iri mu phase winding inogadzikiswa pamutengo unotsanangurwa nevoltage yakapihwa Ua.
Kana uchishandisa constant voltage drive, simba remagetsi rinofanana nerating voltage yemota uye rinoramba riri constant. Constant voltage drives dziri nyore uye dzakachipa pane constant current drives, idzo dzinodzora supply voltage kuti ive nechokwadi chekuti fixed constant current inopihwa kumota. Kune constant voltage drive, resistance yedrive circuit ichaganhurira maximum current, uye inductance yemota ichaganhurira kumhanya uko current inokwira. Pakumhanya kwakaderera, resistance ndiyo inoganhurira kugadzirwa kwe current (uye torque). Mota ine torque yakanaka uye positioning control uye inomhanya zvakanaka. Zvisinei, sezvo motor speed ichiwedzera, inductance nenguva yekukwira kwemagetsi zvinotanga kudzivirira current kusvika pachinangwa chayo. Uyezve, sezvo motor speed ichiwedzera, back EMF inowedzerawo, zvinoreva kuti power supply voltage yakawanda inoshandiswa chete kukunda back EMF voltage. Saka, dambudziko guru re constant voltage drive ndiko kudonha kwe torque nekukurumidza kunogadzirwa ne stepper motor ine stepper speed yakaderera.
Dunhu rekutyaira remota yebipolar stepper rinoratidzwa muMufananidzo 2. Rinoshandisa ma transistors masere kutyaira seti mbiri dzema phases. Dunhu rebipolar drive rinogona kutyaira ma motors ane waya ina kana matanhatu panguva imwe chete. Kunyangwe mota ine waya ina ichingoshandisa dunhu rebipolar drive chete, rinogona kuderedza zvakanyanya mutengo wekushandiswa kwehuwandu. Huwandu hwema transistors mudunhu rebipolar stepping motor drive hwakapetwa kaviri pane hwedunhu reunipolar drive. Ma transistors mana epasi anowanzo fambiswa zvakananga ne microcontroller, uye transistor yepamusoro inoda dunhu repamusoro rinodhura zvakanyanya. Transistor yedunhu rebipolar drive inongoda kutakura voltage yemota, saka haidi dunhu re clamp sedunhu reunipolar drive.
