Za kuwerengera liwiro la geared stepper motor

Mfundo yofunika.

Liwiro la astepper motaimayendetsedwa ndi dalaivala, ndipo jenereta ya chizindikiro mu wolamulira imapanga chizindikiro cha pulse. Poyang'anira mafupipafupi a chiwombankhanga chomwe chimatumizidwa, pamene galimotoyo imasuntha sitepe imodzi mutalandira chizindikiro cha pulse (timangoganizira zoyendetsa masitepe onse), liwiro la galimoto likhoza kuwongoleredwa.

Kuthamanga kwa stepper motor kumatsimikiziridwa ndi kuchuluka kwa dalaivala, masitepe a steppestepper motor ndi gearbox.

pafupipafupi: kuchuluka kwa ma pulse omwe jenereta ya siginecha imatha kupanga pa second

Gawo la pafupipafupi: PPS

Chiwerengero cha kugunda kwa sekondi iliyonse

Chitsanzo: Ngati ma frequency ndi 1000 PPS, zikutanthauza kuti mota imatenga masitepe 1000 pamphindikati.

Liwiro lastepper mota.

Lingaliro la liwiro lozungulira: liwiro lozungulira ndi kuchuluka kwa masinthidwe omwe injini imapanga mugawo la nthawi.

Gawo la liwiro lozungulira: RPS (zosintha pa sekondi iliyonse)

Chiwerengero cha zosinthika Sekondi iliyonse

Gawo la liwiro lozungulira: RPM (kusintha pamphindi)

Chiwerengero cha zosinthika pamphindi

Ndi RPM iti yomwe timati "kuzungulira", kutembenuka kwa 1000 kumatanthauza kutembenuka kwa 1000 pamphindi.

1RPS = 60RPM

 

Ngongole yapagawo: ngodya yozungulira ya mota pagawo lililonse lathunthu.

Ngodya yokhota imodzi ndi 360 °

Mwachitsanzo: mbali ya ma stepper motor yathu yomwe imagwiritsidwa ntchito kwambiri ndi 18 °, zomwe zikutanthauza kuti kuchuluka kwa masitepe ofunikira kuti injini ipitirire kumodzi ndi

360°/20 = 18°

Chitsanzo: Ngati pafupipafupi ndi 1000 PPS, ndi sitepe ngodya ndi 18 °, ndiye

Zikutanthauza kuti injini imatembenuza 1000/20=50 RPS revolutions pamphindikati

RPM pamphindi = 50 RPS * 60 = 3000 RPM pamphindi, zomwe timatcha "3000 RPM"

 

Pankhani ya bokosi la gear: liwiro lotulutsa = liwiro lagalimoto / chiŵerengero chochepetsera bokosi la gear

Chitsanzo: Ngati ma frequency ndi 1000 PPS, masitepe ngodya ndi 18 °, ndipo 100: 1 gearbox amawonjezedwa.

Liwiro lagalimoto pamwambapa litha kutengedwa ku: 50 RPS = 3000 RPM

Ngati 100: 1 gearbox yawonjezedwa, ndiye kuti RPS (zosintha pamphindikati).

50RPS/100=0.5RPS, kutembenuka kwa 0.5 pamphindikati

Ndiye RPM (zosintha pamphindi).

0.5RPS*60 = 30 RPM 30 kuzungulira mphindi

 

Kugwirizana pakati pa RPM ndi pafupipafupi.

s=f*A*60/360° [s: Liwiro lozungulira (gawo: RPM); f: pafupipafupi (gawo: PPS); A: Step angle (gawo: °)]

RPS=RPM/60 [RPS: kuzungulira pamphindi; RPM: kuzungulira pamphindi]
