Motor control safety redundancy mechanism for trains

The invention discloses a motor control safety redundancy mechanism for trains, including a motor body. Air intake hoods are installed on a side of the motor body. Filter screens are installed on a side of the motor body near the air intake hoods. Air exhaust holes are installed in a side of the motor body away from the air intake hoods. Ventilation openings are evenly and equidistantly arranged in the side of a stator core. A bearing is installed on a side of the motor body. A driving shaft is rotationally installed inside the bearing. A first gear is installed outside the driving shaft. An electromagnet is installed on the inner wall of a shell. A second gear is adsorbed below the electromagnet. A third gear is rotationally installed on the side of the shell through a rotating shaft. Airintake is realized through the air intake hoods. The heat inside the motor body is dissipated through the ventilation openings and the air exhaust holes. The second gear is adsorbed through the electromagnet to realize braki
