Iinjini zeStepper kwiirobhothi

Iinjini zeSteppersebenza kumgaqo wokusebenzisa i-electromagnetism ukuguqula amandla ombane abe ngamandla omatshini. Yinjini yokulawula i-loop evulekileyo eguqula imiqondiso ye-pulse yombane ibe yi-angular okanye i-linear displacements. Isetyenziswa ngokubanzi kwiishishini, i-aerospace, iirobhothi, ukulinganisa okulungileyo kunye nezinye iindawo, ezifana ne-photoelectric latitude kunye ne-longitude izixhobo zokujonga i-satellites, izixhobo zomkhosi, unxibelelwano kunye ne-radar, njl. Kubalulekile ukuqonda ii-motor stepper.

 

Kwimeko yokungabikho kokugqithiswa, isantya semoto, indawo yokumiswa ixhomekeke kuphela kwi-frequency ye-pulse signal kunye nenani le-pulses, kwaye ayichaphazeli utshintsho kumthwalo.

 

Xa umqhubi we-stepper efumana umqondiso we-pulse, uqhuba i-motor stepper ukuba iqhube i-motor ye-stepper ukuba iqhube i-fixed point of view kwi-set direction, ebizwa ngokuba yi-"step angle", kwaye ukujikeleza kwayo kuqhuba inyathelo ngesinyathelo kunye nombono osisigxina.

 

Inani lee-pulses linokuthi lisetyenziswe ukulawula ubungakanani be-angular displacement, kwaye emva koko ufikelele kwiinjongo zokubeka ngokuchanekileyo; ngelo xesha, ukuphindaphinda kwee-pulses kungenziwa ukulawula isantya kunye nokukhawuleza kwe-motor rolling, kwaye emva koko ufikelele kwiinjongo zokulawula isantya.

 

Ngokuqhelekileyo i-rotor ye-motor yimagnethi esisigxina, xa i-current igeleza kwi-stator winding, i-stator winding ivelisa i-vector magnetic field. Le ndawo yamagnetic iya kuqhuba i-rotor ukuba ijikeleze indawo yokujonga, ukwenzela ukuba ulwalathiso lwe-rotor ye-magnetic fields lufana nolwalathiso lwentsimi ye-stator. Xa intsimi ye-vector ye-stator ijikeleza ngombono omnye. I-rotor iphinda ilandele le ntsimi ngombono omnye. Kwigalelo ngalinye le-pulse yombane, i-motor iqengqeleka umgca omnye wokujonga phambili. I-angular displacement ye-output ilingana nenani le-pulses input kunye nesantya silingana nokuphindaphinda kwee-pulses. Ngokutshintsha ulandelelwano lwamandla ajikajikayo, i-motor iya kujika. Ke unokulawula inani lee-pulses, ukuphindaphindeka kunye nomyalelo wokunika amandla i-motor windings kwinqanaba ngalinye ukulawula ukuqengqeleka kwe-stepper motor.
