  • the internal generated AC voltage to DC voltage; thereby the operating characteristics of DC generators are still importance, because most concept can be applied to all others electrical machine.
  • A mathematical model and a simulating computer were developed for a particular 0.375 kW d-c machine under both healthy and faulty conditions. The model was based on the coupled-coil theory, with a set of first order differential equations that were solved in the time domain.
  • Should an overhauling load condition persist, the drive may turn itself off, because the dc bus voltage exceeds allowable limits. Reasons for using regenerative AFCs There are several key reasons
  • DC machines have rotating parts and parts which may be live even at rest, and possibly hot surfaces. All operations serving transport, connection, commissioning and periodic maintenance must be carried out by skilled, responsible technical personnel (note EN 60034; EN 50110-1/VDE 0105). Improper handling can cause serious 2 Intended use injury and damage to property. The applicable national
