In a series wound dc generator quizlet
WebSep 7, 2014 · The parallel arrangement of DC series generators are described below: The two DC series motors are disconnected from the supply mains and are connected in parallel to the resistors. During braking the motors continue to run due to the kinetic energy of train and act as self-excited dc series generators generating emfs. WebIn the wound-field DC machine model, the field circuit is represented by an RL circuit. It is connected between the F+ and F− ports of the DC Machine block. In the permanent magnet DC machine model, there is no field current as the magnets establish the excitation flux. KE and KT are constants.
