This work presents the development of a simplified mathematical model, to analyze the acting of the electric motors in machines of improvement of agricultural products. The mathematical model was developed with base in the data of catalogs supplied by the manufacturers of motors. The verification of the acting of a motor, it is made being used only your operational current, measures in your terminals. With the value of this current and of the characteristic curves obtained through the mathematical model, it is possible to determine the necessary greatness to evaluate the acting of the motor, among them, revenue and potency factor, being also possible, to obtain the necessary greatness to evaluate the global acting of a machine of improvement of agricultural products, among them the active potencies and it reactivates and look, the potency factor, which are fundamental for studies related with the electric power rationalization. The model was applied her/it a machine of improvement of rice, and the results obtained through simulations in computer, they allowed to verify the acting and the shipment of each motor of the machine.
