Abstract
Inventia se refera la o metoda si o siguranta electronica de suprasarcina pentru controlul curentului efectiv la masini de curent continuu, care consta în scaderea patratului curentului nominal din patratul curentului real si folosirea marimii obtinute în urma integrarii în timp ca etalon pentru sarcina dispozitivului de actionare si pentru controlul sarcinii, siguranta fiind realizata din circuite consacrate pentru realizarea acestor operatii.
