Mochini oa EDM oa boleng bo holimo hammoho le tlhokomelo e nepahetseng o fana ka ts'ebetso e tsitsitseng ea ho sebetsa ka mochini le litšenyehelo tse tlase tsa beng ba ona.
Qetello
Mathata a mangata a ho sebetsa ka mechine ea EDM a ka thibeloa ka khetho e nepahetseng ea liparamente, tlhokomelo e tloaelehileng, le ts'ebetso e nepahetseng ea mochini.
Hore na o sebetsana le qetello e mpe ea bokaholimo, ho senyeha ho feteletseng ha li-electrode, ho phatloha ho sa tsitsang ha li-spring, kapa lebelo le liehang la ho sebetsa, ho tseba sesosa sa mantlha ke mohato oa pele o lebisang tharollong e sebetsang.
Haeba o batla mochini o tšepahalang oa EDM kapa o hloka likeletso tsa tekheniki bakeng sa ts'ebeliso ea hau, sehlopha sa rona se nang le boiphihlelo se ikemiselitse ho thusa. Ikopanye le rona bakeng sa likhothaletso tsa mochini, tšehetso ea ho rarolla mathata, le litharollo tsa EDM tse ikhethileng bakeng sa ho etsa hlobo le tlhahiso e nepahetseng.
