Stepper motorsanowanzo shandiswa pakumisikidza nekuti anodhura, ari nyore kutyaira, uye anogona kushandiswa mune yakavhurika-loop masisitimu-kureva, mota dzakadai hadzidi mhinduro yechinzvimbo se.servo motorsita.Stepper motors inogona kushandiswa mumakina madiki maindasitiri senge laser engravers, 3D maprinta, uye zvishandiso zvemuhofisi senge laser printers.
Stepper motors inowanikwa mune dzakasiyana siyana sarudzo.Kune maindasitiri ekushandisa, maviri-chikamu hybrid stepper motors ane 200 nhanho per revolution akajairika.
MechanicalConsiderations
Kuti uwane kurongeka kunodiwa kana micro-nhanho, vagadziri vanofanirwa kutarisisa kune mechanic system.
Pane nzira dzakawanda dzekushandisa stepper motors kugadzira linear motion. Nzira yekutanga ndeye kushandisa mabhandi uye pulleys kubatanidza iyomotakune zvikamu zvinofamba.Muchiitiko ichi, kutenderera kunoshandurwa kuita mutsara wekufamba.Nhambwe inofambiswa ibasa rekona yekufamba kwemota uye dhayamita yepulley.
Yechipiri nzira ndeye kushandisa sikuruu kanabhora sikuruu.A stepper mota yakabatana zvakananga kumagumo eiyoscrew, kuitira kuti nati ifambe nenzira yemutsara sezvo screw inotenderera.
Muzviitiko zvese izvi, kunyangwe paine chaiyo mutsara kufamba nekuda kweiyo yega diki-nhanho zvinoenderana neiyo friction torque.Izvi zvinoreva kuti torque yefriction inofanirwa kudzikiswa kuitira kuti iwane kunyatsojeka.
Semuyenzaniso, akawanda screws uye bhora screw nzungu ane yakati wandei preload kugadzirisa-kugona.Preload isimba rinoshandiswa kudzivirira backlash, izvo zvinogona kukonzera kumwe kutamba muhurongwa.Nekudaro, kuwedzera preload kunoderedza backlash, asiwo kunowedzera kupokana.Naizvozvo, pane kutengeserana pakati pe backlash uye friction.
Be CazereWhenMikro-Stepping
Paunenge uchigadzira dhizaini yekudzora sisitimu uchishandisa stepper motors, hazvigone kufungidzirwa kuti iyo yakatemerwa inobata torque yemota icharamba ichishanda kana micro-nhanho, sezvo iyo incremental torque ichaderedzwa zvakanyanya, izvo zvinogona kutungamirira kune zvisingatarisirwi zvikanganiso zvekumira.Mune zvimwe zviitiko, kuwedzera iyo micro-nhanho kugadziriswa hakugadzirisi kurongeka kwehurongwa.
Kuti ukunde zvipimo izvi, zvinokurudzirwa kudzikisira torque mutoro pamota, kana kushandisa mota ine yakakwira yakabata torque rating.Kazhinji, mhinduro yakanakisa ndeyekugadzira iyo mechanika system kushandisa yakakura nhanho increments pane kuvimba neakanaka micro-nhanho.Stepper mota madhiraivha anogona kushandisa 1/8th yenhanho kupa yakafanana mechaniki kuita seyakajairwa, inodhura madhiraivha ekutsika.
