Zokhudza kuwerengera liwiro la mota yoyendera ma stepper

Mfundo.

Liwiro lamota ya stepperimayendetsedwa ndi dalaivala, ndipo jenereta ya chizindikiro mu chowongolera imapanga chizindikiro cha pulse. Mwa kulamulira kuchuluka kwa chizindikiro cha pulse chomwe chimatumizidwa, pamene mota ikuyenda sitepe imodzi mutalandira chizindikiro cha pulse (timangoganizira za step drive yonse), liwiro la mota likhoza kulamulidwa.

Liwiro la mota yoyendera limatsimikiziridwa ndi kuchuluka kwa dalaivala, ngodya ya sitepe yamota ya stepper ndi gearbox.

Kuchuluka kwa ma pulses: kuchuluka kwa ma pulses omwe jenereta ya chizindikiro imatha kupanga pa sekondi iliyonsend

Gawo la pafupipafupi: PPS

Chiwerengero cha kugunda kwa mtima pa sekondi iliyonse

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

Liwiro lamota ya stepper.

Lingaliro la liwiro lozungulira: liwiro lozungulira ndi chiwerengero cha ma revolutions omwe injini imapanga mu unit of time.

Gawo la liwiro lozungulira: RPS (kusintha kwa sekondi imodzi)

Chiwerengero cha ma revolutions Pa sekondi iliyonse

Gawo la liwiro lozungulira: RPM (kusintha kwa mphindi imodzi)

Chiwerengero cha kusintha kwa mphindi imodzi

Ndi RPM iti yomwe nthawi zambiri timati "kuzungulira", ma revolutions 1000 amatanthauza ma revolutions 1000 pamphindi.

1RPS=60RPM

 

Ngodya ya sitepe: ngodya ya kuzungulira kwa mota pa sitepe iliyonse yathunthu.

Ngodya ya kutembenuka kamodzi ndi 360 °

Mwachitsanzo: ngodya ya sitepe ya mota yathu yoyendera yomwe imagwiritsidwa ntchito kwambiri ndi 18°, zomwe zikutanthauza kuti chiwerengero cha masitepe ofunikira kuti mota ipite kuzungulira kamodzi ndi

360° / 20 = 18°

Chitsanzo: Ngati ma frequency ndi 1000 PPS, ndipo ngodya ya sitepe ndi 18°, ndiye kuti

Zimatanthauza kuti mota imasinthasintha 1000/20 = 50 RPS pa sekondi iliyonse

RPM pamphindi = 50 RPS * 60 = 3000 RPM pamphindi, chomwe timachitcha "3000 RPM"

 

Pankhani ya bokosi la gearbox: liwiro lotuluka = ​​liwiro la injini/chiŵerengero chochepetsera giya

Chitsanzo: Ngati ma frequency ndi 1000 PPS, ngodya ya sitepe ndi 18°, ndipo bokosi la gearbox la 100:1 limawonjezedwa.

Liwiro la injini pamwambapa likhoza kupezeka kuchokera ku: 50 RPS = 3000 RPM

Ngati bokosi la gearbox la 100:1 lawonjezeredwa, ndiye kuti RPS (ma revolutions pa sekondi) ndi

50RPS/100=0.5RPS, ma revolutions 0.5 pa sekondi

Kenako RPM (ma revolutions pa mphindi).

0.5RPS*60 = 30 RPM 30 revolutions pa mphindi

 

Ubale pakati pa RPM ndi ma frequency.

s=f*A*60/360° [s: Liwiro lozungulira (gawo: RPM); f: Mafupipafupi (gawo: PPS); A: Ngodya ya sitepe (gawo: °)]

RPS=RPM/60 [RPS: ma revolutions pa sekondi; RPM: ma revolutions pa mphindi]
