Development of Children and Adolescents machine is very well suited for this duty; it is, in fact, the only one that could be used at a power level of, possibly, several hundred MW. Problems with large synchronous motors operating on a constant frequency supply may be caused by the inherent oscillatory response and the required start-upTHE 发表于 2025-3-27 14:41:03
Vertrauen, Misstrauen und Medienfor linearisation. Once the torque loop with the equivalent lag . is closed, there is little difference between a DC and an AC drive. By limiting the torque reference, protection of the power converter and the mechanical load is achieved. Torque control is mandatory on high performance drives, excepCarcinoma 发表于 2025-3-27 20:03:35

These conversions constitute the advantages of the control scheme (separate electrical circuits, decoupling by rotating masses) as well as its drawbacks (cost of machines, foundations, power losses, servicing, limited speed of response).
