The invention relates to a forced ventilation system in DC electric traction motors of locomotives. According to the invention, the system is mounted between the ventilation air pipe system (1) and the power supply (9) of the locomotive and it comprises ventilation motors (2) supplied from a system of converters and inverters (3) with variable voltage and frequency depending on the data supplied by a programmable logic controller (4), load current sensors (5) and ambient temperature sensors (6), a data display device (7) mounted in the locomotive driving cabin and a memory card (8) for recording the operating parameters of the ventilation, of the sensors and the electric traction motors. Invenţia se referă la o instalaţie de ventilaţie forţată a motoarelor electrice de tracţiune de curent continuu ale locomotivelor. Instalaţia, conform invenţiei, este montată între sistemul de canale de aer de ventilaţie (1) şi sursa de curent (9) a locomotivei şi cuprinde motoare de ventilaţie (2) alimentate de la un sistem de convertoare şi invertoare (3) cu tensiune şi frecvenţă variabile pe baza datelor furnizate de un automat programabil (4), de nişte senzori de curent de sarcină (5) şi nişte senzori de temperatură a mediului (6), un display (7) de afişare a datelor montat în cabina de conducere a locomotivei şi un card de memorie (8) pentru înregistrarea parametrilor de funcţionare ai ventilaţiei, senzorilor şi motoarelor electrice de tracţiune.
