Isethulo se-motor yesigaba ezimbili:
Ukulawulwa kwe-stepper motor kwangempela kulula kakhulu, uhlelo lokusebenza luyiziwula, abakhiqizi benza umsebenzi omuhle womshayeli we-stepper motor, i-stepper motor ukuthi isebenza kanjani umshayeli ukulawula, akudingeki senze ukuqonda okujulile kwe-stepper motor. , inqobo nje uma wazi ukuthi ukusetshenziswa kwendlela yomshayeli we-stepper motor kungaba. Yebo izici ezilula zokusebenza kwe-stepper motor, noma okufanele wazi, ngizozethula ngezansi!
Indima yokuhlukaniswa iziqephu:
I-motor enezigaba ezimbili, i-engeli eyisisekelo yesinyathelo esingu-1.8 degrees, okungukuthi: ama-pulses motor angu-200 aphendulela indingilizi, ebizwa ngokuthi yisinyathelo sonke.
Umsebenzi wokuhlukaniswa kweziqephu ungasethwa kumshayeli we-stepper motor:
Uma isethelwe ku-2 subdivisions (ebuye ibizwe ngokuthi i-half-step), i-engeli yesinyathelo ingu-0.9 degrees, ama-pulses angu-400 aphendulela indilinga.
Uma isethelwe ezigabeni ezi-4, i-engeli yesinyathelo ingu-0.45 degrees bese kuthi ama-pulses angu-800 azungeze.
Uma isethelwe ekuhlukaniseni okungu-8, i-engeli yesinyathelo ingu-0.225 degrees bese kuthi ama-pulses angu-1600 azungeze.
Uma kuphakeme ukuhlukaniswa iziqephu, buncane ubude bokushaya kwenhliziyo okuthunyelwa ikhompyutha engumsingathi, kuyanda ukunemba! Lokhu kuqondwa kahle, i-pulse ukuya ku-10 mm, iphutha le-10%, iphutha le-pulse lika-1 mm, i-pulse ukuya ku-1 mm, iphutha elifanayo le-10%, iphutha le-pulse lika-0.1 mm.
Yiqiniso, asikwazi ukusetha ingxenyenamba emihle kakhulu, ukuze sifinyelele inhloso ye-pulse ngayinye ukuhamba ubude obuncane kakhulu.
Uyakhumbula izigaba ezimbili ze-stepper motor 200 pulses ukuze uphendule indilinga kulayini! Uma kukhulu ukuhlukaniswa, likhulu inani lama-pulses ekujikelezweni okukodwa kwe-stepper motor!
Kuhunyushwe nge-DeepL.com (inguqulo yamahhala)
Uma sifuna ukuthi isitebhisi sihambe ngo-400 mm ngama-revolution angu-600 ngomzuzu, sibala kanjani inani lama-pulses kanye nemvamisa ye-pulse i-OP edinga ukuyithumela?
Sililawula kanjani isivinini se-stepper motor (okungukuthi, sibala kanjani i-pulse frequency):
Uma sicabanga ukuthi ukulungiselelwa kuyizingxenyana ezine ezinhle, inani lama-pulses adingekayo ukuze injini yenze inguquko eyodwa, okungukuthi, 800, ukuze kuzuzwe isivinini se-stepper motor esingu-600 rpm, ukubalwa kwemvamisa yama-pulses okufanele athunyelwe umsingathi. ikhompuyutha:
Umqondo wefrequency inombolo yama-pulses athunyelwa ngomzuzwana owodwa.
Ngakho-ke, qala ubale inani lama-revolution ngomzuzwana we-stepper motor
600/60 = ama-revolution angu-10 ngomzuzwana
Bese ubala inani lama-pulses adingekayo kuma-revolution angu-10/sec.
10 X 800 = 8000
Okusho ukuthi, imvamisa ye-pulse ingu-8000, noma 8K.
Isiphetho, ukuze ukwazi ukubona isivinini se-stepper motor esingu-600 rpm, ikhompuyutha ephethe kufanele igcine imvamisa yokuphuma kwe-pulse engu-8K.
Manje niyaqonda? Ukuze ubale imvamisa ye-pulse kufanele wazi izimfuneko ezimbili yilezi:
1, yazi inani lama-pulses adingekayo ekuguqukeni okukodwa kwe-stepper motor;
2, yazi isivinini sokujikeleza se-stepper motor, iyunithi yejubane ejikelezayo ithi: ama-revolutions per
Ungabala kanjani inani lama-pulses adingwa yi-stepper motor.
Uma sicabanga ukuthi ukusetha kuyizingxenyana ezine ezinhle, inani lama-pulses adingekayo ukuze injini iphendule indilinga ingu-800, futhi ukuqaphela ukuthi i-stepper motor ihamba ibanga elingu-400 mm, ukubalwa kwenani lama-pulses okufanele athunyelwe ikhompyutha ephezulu:
Uma i-shaft ephumayo ye-stepper motor nesikulufa (iphimbo: 10mm) ukuxhumana okuqondile, noma nge-pulley drive, isiyingi sesondo esingu-10mm. Okusho ukuthi, i-stepper motor ukujika indilinga, ubude bokuhamba komshini 10mm.
Inombolo yama-pulses ye-revolution eyodwa ye-motor ingu-800, bese ubude bokuhamba kwe-pulse:
10mm / 800 = 0.0125 mm
Inombolo yama-pulses adingekayo ukuze uhambe u-400mm:
400 / 0.0125 = 32000 ama-pulses
Isiphetho, ukuze uthole ibanga elingama-400 mm elihanjwa yi-stepper motor, inani lama-pulses okufanele lithunyelwe yi-computer host yi-32000.
Uyaqonda manje? Izimfuneko ezintathu okufanele zaziwe ukuze kubalwe inani lama-pulses yilezi:
1, yazi inani lama-pulses adingekayo ekuguqukeni okukodwa kwe-stepper motor;
2, yazi i-stepper motor ukujika indilinga yobude bokuhamba;
3, yazi ubude bohambo oludingekayo yi-stepper motor;
Uma sifuna ukuthuthukisa ukunemba, singakwazi ukwandisa ukuhlukaniswa, uma ukuhlukaniswa kusethelwe ku-64 Inani lama-pulses adingekayo ekuguqukeni okukodwa kwe-motor yile:
64 X 200 = 12800
Ubude be-pulse ehanjiwe buyi:
10mm / 12800 = 0.00078 mm
Inani lama-pulses adingekayo ukuze ahambe 400 mm:
400 / 0.00078 = 512000 ama-pulses
Ukuze ufinyelele isivinini esingu-600 rpm, imvamisa yama-pulses okufanele ithunyelwe yikhompyutha engumsingathi yile:
( 600 / 60 ) X 12800 = 128000
Okusho ukuthi: 128K
