Abstract
Procedure for the automatic protection of a DC machine against a mechanical overload, particularly of a machine provided with an automatic regulation system of the excitation in relation to the resistant torque, characterized by the fact that it is subtracted at every moment, a tension proportional to the acceleration or deceleration of the machine of a voltage proportional to the current of the armature, comparing the voltage representing the difference of these two voltages, on the one hand with a first voltage corresponding to the supported torque allowed at a desired speed of the machine, and on the other hand, with a second voltage corresponding to the maximum resistive torque admitted at the nominal speed, also being characterized by the inactivity of the automatic regulation system of the excitation, when the voltage representing the difference is greater than the aforementioned first tension and why is it in terrumpe the feeding of the machine when it is greater than the referred second tension.
