DC series motor has been the most used solution for the traction of locomotives, trolleybuses, trams and others, characterized by a speed and torque control using additional resistances, which means a low efficiency, electromechanical contactors, high maintenance costs, dynamic braking in resistances. In this paper a novel 4 quadrant full control for DC series motor drive is presented. A prototype was designed using IGBTs and it was tested at the Metro workshop. It is a very good solution for re-visiting and improvement of old drives that uses DC motors. The proposed drive is supported by a USA patent, obtained in 2007(US 7.274.865).
