WebSep 14, 2024 · Calculation of the starting time of a motor. Making reference to the data of the above table, here is an example of calculation of the starting time of a motor, according to the theoretical treatment previously developed. Cacc = 0.45 · ( C S + C max) – K L · C L = 0.45 · (2467 + 2981) – (1 · 1600) = 851.6 Nm. WebThe AC4 motor drive is a DTC three-phase induction motor-based drive. The DC2 motor drive is a single-phase dual-converter DC motor drive. In such a system, one drive is speed regulated while the other is torque regulated, but each drive can operate either as a motor or as a generator, as will be seen later.
