SAFETY DEVICE FOR ELECTRICAL BRAKING WITH PERMANENT MAGNET MOTOR AND BRAKING TORQUE REGULATION

摘要

This safe electric braking device for an electric traction vehicle makes it possible to improve the force / speed characteristic of the vehicle and comprises a rotating permanent electromechanical machine (10) having at least one winding with electrical terminals (13, 14, 15), a device for producing a rheostatic braking torque (26), and switching means (20) for connecting the electrical terminals (13), (14), (15) of the electromechanical machine (10). the device for producing a braking torque (26). It is characterized in that at least one inductor (116), (118), (120) is electrically connected in series between the braking torque generating device (26) and the electromechanical machine (10).
