AC Variabilis Frequency Drive Drawworks
• Partes principales ducum sunt AC variabilis frequentiae motor, calces reductor, discus hydraulicus confregit, machinam winch, tympanum stipes conventus et terebra automataria etc., magna cum efficientia transmissionis calces altae.
• Calces oleum tenue lubricum est.
• Drawwork est tympani unius spiculi structura et tympanum sulcata. Comparata similibus operibus, multorum meritorum est, ut structura simplex, volumen parvum, et leve pondus.
• Est AC variabilis frequentia motoria coegi ac sine gressus regulatio in toto cursu, cum magna potentia et lato velocitate range aptabilis.
• Praecipua fregit adhoc discus hydrau- lis fregit, et discus fractus est aqua vel aer refrigeratus.
• Fregit auxiliaris est braking dynamica motoria.
• cum automatis motoriis independentibus instructus exercendis rationibus.
