Magawo ovotera awa motsatana akuyimira mphamvu zosiyanasiyana za injini.

Mu dzina lachinthu cha injini, magawo angapo ofunikira monga mphamvu yovotera, magetsi ovotera, magetsi ovotera ndi kuchuluka kwa injini kudzafotokozedwa. Pakati pa magawo angapo ovotera, ndi magawo oyambira kutengera mphamvu yovotera ngati chimango choyambira; pa mphamvu yamagetsi Mota, pamene magetsi ovotera, magetsi ovotera ndi kuchuluka kwa injini zikukwaniritsa zofunikira, mota imatha kugwira ntchito bwino. Pansi pa mkhalidwe wovotera wofanana, mota imatha kutulutsa mphamvu yovotera, yomwe imawonetsedwa makamaka mu kuthekera kwa mota kukoka katundu. Pa ma mota ovotera osiyanasiyana, chifukwa cha kusintha kwa mawonekedwe a mphamvu yolowera, njira yonse yogwirira ntchito ya mota imayendetsedwa pansi pa mphamvu yovotera komanso nthawi yovotera kuti zitsimikizire chitetezo cha ntchito ya mota. Mwa kungofotokoza mwachidule magawo ovotera awa a mota, amatha kugawidwa m'magawo awiri: chitetezo chamakina ndi chitetezo chamagetsi.

Chitetezo cha makina a injini chimadziwika ndi mphamvu yoyesedwa. Kukula kwa mphamvu ya injini kumakhudza mwachindunji momwe makina operekera mphamvu amagwirira ntchito komanso shaft yozungulira. Mwachitsanzo, pa mota yolemera, iyenera kufananizidwa ndi ma bearing omwe amatha kunyamula katundu wokulirapo; mphamvu ya injiniyo ikakhala yayikulu, idzakhala ndi zotsatirapo zoyipa pa khalidwe la makina operekera mphamvu; nthawi yomweyo, kuwonjezera pa khalidwe la makina operekera mphamvu, mphamvu yayikulu ingayambitse kuti shaft itembenuke kapena kusweka, makamaka pa ma shaft olumikizidwa, kuchuluka kwa zotsatirapo zoyipa kudzakhala kwakukulu.

Chitetezo cha magetsi cha mota chimadziwika ndi magetsi ovoteledwa ndi magetsi ovoteledwa. Pamene magetsi ovoteledwa ali akulu, magetsi ovoteledwa pakati pa kuzungulira amawonjezeka, zomwe zimapangitsa kuti kutsekeka kwa magetsi ovoteledwa pakati pa kuzungulira kusadalire; pamene magetsi ovoteledwa ndi okwera kwambiri, kuzungulira kumakhudza mwachindunji kuchuluka kwa magetsi chifukwa cha mphamvu yaikulu yamagetsi, ndipo kuchuluka kwa magetsi ovoteledwa kungayambitse kutentha kwambiri. Woyendetsa galimoto amatentha kwambiri, ndipo zotsatira zake zomaliza ndi kutentha kwambiri, komwe kumawopsezanso kudalirika kwa magetsi a mota.

Chifukwa chake, kaya ndi mota ya frequency yogulitsa kapena mota ya frequency yosinthasintha, chitetezo cha ntchito yake chimadalira chitetezo cha makina ndi chitetezo chamagetsi. Kupatuka kulikonse kuchokera ku mikhalidwe yoyesedwa kudzakhala ndi zotsatirapo zoyipa pa mota.
