Ubale pakati pa mphamvu zamagalimoto, liwiro ndi torque

Lingaliro la mphamvu ndi ntchito yochitidwa pa nthawi ya unit.Pansi pa chikhalidwe cha mphamvu inayake, kuthamanga kwapamwamba, kutsika kwa torque, ndi mosemphanitsa.Mwachitsanzo, yemweyo 1.5kw galimoto, makokedwe linanena bungwe la siteji 6 ndi apamwamba kuposa siteji 4.Fomula M=9550P/n itha kugwiritsidwanso ntchito powerengera movutikira.

Kwa ma motors a AC: ovotera makokedwe = 9550 * ovotera mphamvu / liwiro; kwa ma DC motors, ndizovuta kwambiri chifukwa pali mitundu yambiri.Mwinamwake liwiro lozungulira ndilofanana ndi voteji ya armature ndipo mosagwirizana ndi voteji yosangalatsa.Torque imayenderana ndi kusinthasintha kwa m'munda ndi zida zamagetsi.

• Kusintha mphamvu yamagetsi mu kayendetsedwe ka liwiro la DC ndikwanthawi zonse kuthamanga kwa torque (makokedwe amoto sasintha)
• Mukakonza voteji yachisangalalo, imakhala yanthawi zonse kuthamanga kwamagetsi (mphamvu yotulutsa yagalimoto imakhala yosasinthika)

T = 9.55 * P / N, T linanena bungwe, P mphamvu, N liwiro, galimoto katundu amagawidwa mu mphamvu yosalekeza ndi makokedwe zopingasa, torque nthawi zonse, T amakhalabe zosasintha, ndiye P ndi N ndi ofanana.Katunduyo ndi mphamvu yosalekeza, ndiye T ndi N ndizosiyana mosiyanasiyana.

Torque = 9550 * mphamvu zotulutsa / liwiro lotulutsa

Mphamvu (Watts) = Liwiro (Rad/sec) x Torque (Nm)

M'malo mwake, palibe chokambirana, pali chilinganizo P=Tn/9.75.Chigawo cha T ndi kg·cm, ndi torque=9550* mphamvu yotulutsa/liwiro lotulutsa.

Mphamvu ndi yotsimikizika, liwiro liri mwachangu, ndipo torque ndi yaying'ono. Nthawi zambiri, pakafunika torque yayikulu, kuwonjezera pa mota yokhala ndi mphamvu yayikulu, chotsitsa chowonjezera chimafunika.Zitha kumveka motere kuti mphamvu P ikadali yosasinthika, kuthamanga kwambiri, kumachepetsa torque.

Titha kuwerengera motere: ngati mukudziwa kukana kwa torque T2 ya zida, liwiro lovotera n1 la mota, liwiro la n2 la shaft yotulutsa, ndi zida zoyendetsa f1 (f1 iyi imatha kufotokozedwa molingana ndi zenizeni. Zomwe zikuchitika pamalowa, zoweta zambiri zimakhala pamwamba pa 1.5) ndi mphamvu yamagetsi m'galimoto (ndiko kuti, chiŵerengero cha mphamvu yogwira ntchito ku mphamvu zonse, zomwe zimamveka ngati kagawo kakang'ono kameneka kameneka kameneka kameneka kameneka, kawirikawiri pa 0.85), timawerengera mphamvu yake yamagalimoto P1N.P1N>=(T2*n1)*f1/(9550*(n1/n2)*m) kuti mupeze mphamvu ya mota yomwe mukufuna kusankha panthawiyi.
Mwachitsanzo: makokedwe ofunikira ndi zida zoyendetsedwa ndi: 500N.M, ntchitoyo ndi maola 6/tsiku, ndipo zida zoyendetsedwa ndi f1 = 1 zitha kusankhidwa ndi katundu wofananira, chochepetsera chimafunikira kuyika kwa flange, ndi liwiro lotulutsa. n2=1.9r/mphindi Kenako chiŵerengero:
