Fokotsa tlhahiso ea mocheso, ke ho fokotsa tahlehelo ea koporo le tahlehelo ea tšepe. Fokotsa tahlehelo ea koporo ka litsela tse peli, fokotsa ho hanyetsa le hona joale, e leng se hlokang khetho ea khanyetso e nyenyane le e lekantsoeng ea hona joale e nyenyane ka hohle kamoo ho ka khonehang ha motlakase, motlakase oa mekhahlelo e 'meli, o ka sebelisa mochine ka letoto ntle le parallel motor. Empa hangata sena se hanana le litlhoko tsa torque le lebelo le phahameng. Bakeng sa enjene e khethiloeng, ts'ebetso ea ho laola halofo ea hajoale ea koloi le ts'ebetso e kantle ho marang-rang e lokela ho sebelisoa ka botlalo, ea pele e fokotsa hona joale ha enjene e phomotse, 'me ea morao-rao e khaola ea hona joale. Ho phaella moo, koloi ea karohano, hobane waveform ea hona joale e haufi le sinusoidal, e fokolang ea harmonics, mocheso oa motlakase le oona o tla fokotseha. Ho na le mekhoa e fokolang ea ho fokotsa tahlehelo ea tšepe, 'me boemo ba motlakase bo amana le eona. Le hoja motlakase o tsamaisoang ke motlakase o phahameng o tla tlisa keketseho ea litšobotsi tse phahameng, e boetse e tlisa keketseho ea tlhahiso ea mocheso. Kahoo o lokela ho khetha boemo bo nepahetseng ba motlakase oa koloi, ho nahanoa ka lebelo le phahameng, boreleli le mocheso, lerata le matšoao a mang.

Bakeng sa mefuta eohle ea li-motors tsa stepper, bokahare bo entsoe ka mokokotlo oa tšepe le khoele e matsoelintsoeke. Maqhubu a na le ho hanyetsa, a matlafalitsoeng a tla hlahisa tahlehelo, boholo ba tahlehelo bo lekana le lisekoere tsa ho hanyetsa le hona joale, tseo hangata li bitsoang meteor ea koporo, haeba hona joale e se e tloaelehileng ea DC kapa sine wave, empa hape le tahlehelo ea harmonic; core e na le phello ea hona joale ea hysteresis eddy, sebakeng se fapaneng sa matla a khoheli le sona se tla hlahisa tahlehelo, boholo ba thepa, hona joale, frequency, voltage, e bitsoang tahlehelo ea tšepe.
