Pfungwa yesimba ibasa rinoitwa panguva yeyuniti.Pasi pemamiriro erimwe simba, iyo yakakwirira kumhanya, inodzika torque, uye zvinopesana.Semuenzaniso, iyo yakafanana 1.5kw mota, iyo inobuda torque yechitanhatu nhanho yakakwira kupfuura yechina.Iyo formula M=9550P/n inogona zvakare kushandiswa kuita rough calculation.
Kune AC motors: yakayerwa torque = 9550 * yakayerwa simba / yakayerwa kumhanya;yeDC mota, zvinonetsa nekuti kune marudzi akawandisa.Pamwe kumhanya kwekutenderera kunoenzana neiyo armature voltage uye inversely proportional kune excitation voltage.Torque yakaenzana nemunda flux uye armature ikozvino.
- Kugadzirisa iyo armature voltage muDC yekumhanyisa mutemo ndeyekugara torque kumhanya mutemo (iyo inobuda torque yemota haina kuchinjika)
- Kana uchigadzirisa magetsi ekusimudzira, ndeye anogara achimhanyisa simba regulation (simba rekubuda remota harina kuchinjika)
T = 9.55 * P/N, T inobuda torque, P simba, N kumhanya, mutoro wemota wakakamurwa kuita simba risingaperi uye torque inochinjika, torque inogara iripo, T inoramba isina kuchinjika, ipapo P uye N zvakaenzana.Mutoro isimba rinogara riripo, ipapo T neN zvine mwero wakasiyana.
Torque = 9550 * simba rekubuda / kubuda nekukurumidza
Simba (Watts) = Kumhanya (Rad/sec) x Torque (Nm)
Muchokwadi, hapana chekukurukura, pane formula P = Tn/9.75.Iyo unit yeT ikg·cm, uye torque = 9550* simba rekubuda/kubuda nekukurumidza.
Simba nderechokwadi, kumhanya kunokurumidza, uye torque idiki.Kazhinji, kana torque yakakura ichidikanwa, kuwedzera kune mota ine simba rakakura, imwe inoderedza inodiwa.Inogona kunzwisiswa nenzira iyi kuti kana simba P rikaramba risina kuchinjwa, iyo yakakwirira kumhanya, idiki inobuda torque.
Tinogona kuzviverenga seizvi: kana iwe uchiziva torque kuramba T2 yemidziyo, iyo yakatemerwa kumhanya n1 yemota, kumhanya n2 yekubuda shaft, uye dhiraivha dhizaini system f1 (iyi f1 inogona kutsanangurwa zvinoenderana neiyo chaiyo. Mamiriro ekushanda panzvimbo, mazhinji edzimba ari pamusoro pe1.5) uye iyo simba factor m yemota (ndiko kuti, chiyero chesimba rinoshanda kune simba rose, iro rinogona kunzwisiswa seyakazara chiyero mumhepo inotenderera, kazhinji. pa 0.85), isu tinoverenga yayo mota simba P1N.P1N>=(T2*n1)*f1/(9550*(n1/n2)*m) kuti uwane simba remota yaunoda kusarudza panguva ino.
Semuenzaniso: torque inodiwa nemidziyo inotyairwa ndeye: 500N.M, basa iri maawa matanhatu / zuva, uye inotyairwa yemidziyo coefficient f1 = 1 inogona kusarudzwa nemutoro wakafanana, chinoderedza chinoda kuisirwa flange, uye kumhanya kwekubuda. n2=1.9r/min Zvadaro chiyero:
