Taurin kai da taurin kai:
Tsanantawa yana nufin ikon abu ko tsari don tsayayya da lalacewar roba lokacin da aka tilasta shi, kuma halayya ce ta wahalar lalacewar roba na wani abu ko tsari. Measuredarfin kayan abu yawanci ana auna shi ne ta hanyar haɓakar elasticity E. A cikin kewayen macro na roba, taurin shine gwargwadon daidaiton nauyin ɓangaren da sauyawa, wanda shine ƙarfin da ake buƙata don haifar da ƙaura naúrar.

k = M / θ
M shine lokacin kuma θ shine kusurwar juyawa.

Menene dacewar inertia?
Dangane da Dokar Niu Er:
Tsarin da ake buƙata na tsarin ciyarwa = tsarin lokaci na rashin ƙarfi J × angular hanzari θ
Aramar saurin kusurwa θ, mafi tsayi lokaci daga mai sarrafawa zuwa ƙarshen aiwatarwar tsarin, kuma jinkirin saurin tsarin. Idan θ ya canza, amsar tsarin zai canza da sauri kuma a hankali, wanda zai shafi ingancin aikin.
Bayan an zaɓi motar sabis, matsakaicin ƙimar fitarwa ba ta canzawa. Idan kuna son canjin θ ya zama karami, to J ya zama karami kamar yadda ya yiwu.
Tsarin lokaci na rashin ƙarfi J = saurin sabis na juyawa mai saurin ƙarfin JM + motar motsi mai jujjuyawar ƙarfin ƙarfin JL.
JL inertia JL an hada shi da rashin ingancin aiki, tsayarwa, kayan aiki, dunƙule, haɗuwa da sauran layuka masu juzu'i da juyawa zuwa tubalin mashin din. JM rashin kuzari ne na na'urar komputa. Bayan an zaɓi motar sabis, wannan ƙimar ta ƙayyadadden ƙima ce, yayin da JL ke canzawa tare da canjin kayan aiki. Idan kuna son ƙarancin canjin J ya zama ƙarami, zai fi kyau ku rage girman JL karami. Gabaɗaya magana, motar mai ƙananan inertia tana da aikin taka birki mai kyau, saurin amsawa don farawa, hanzari da tsayawa, da kuma kyakkyawan saurin saurin saurin juyawa, wanda ya dace da wasu nauyin haske da lokutan saiti mai sauri. Matsakaici da manyan inertia Motors sun dace da manyan kaya da buƙatun kwanciyar hankali mai girma, kamar wasu hanyoyin motsi na madauwari da wasu masana'antun kayan aikin inji.
Don haka rashin daidaituwa na motar servo AC yayi yawa kuma tsaurin bai isa ba. Gabaɗaya, fa'idar direban sabis ɗin AC ya kamata a daidaita shi don canza tsarin amsawa. Rashin intertia yayi yawa kuma inertia din bata isa ba. Kwatancen dangi ne tsakanin canjin canjin nauyi da rashin karfin AC servo motor.
Kari akan haka, ya kamata a yi la’akari da tasirin mai reducer akan tsayayyen kaya: gearbox na iya canza yanayin rashin dacewar aiki. Gabaɗaya, lokacin da raunin rashin nauyi na motar ya wuce 5, ana ɗaukar mai ragewa don inganta dacewar inertia. Yanayin inertia ya daidaita daidai da murabba'in ragin raguwa.
