Lorentz formula is applied here to calculate the electromagnetic forces acting on the stator end windings of a turbogenerator within the first several periods after it is suddenly short circuited, based on the magnetic field computed by the transient quasi-3D method (TQM). The principle of TQM and its essence-processing of winding currents-have been disussed. In the example, the forces acting on the stator end windings of a 35MW turbogenerator have been computed, when it is under no-load three phase, no-load line-to-line and noload line-to-neutral sudden short circuit conditions. Some useful results are obtained. © 1956 IEEE. (EN)
