Exhaust brake valve driving motor and exhaust brake valve assembly

The utility model discloses an exhaust brake valve drive motor and an exhaust brake valve assembly, which comprise a drive end and an output end, a stator assembly and a rotor assembly are combined to form the drive end, and after the stator assembly is electrified, the rotor assembly is driven to move in the stator assembly to generate torque; the gear pair is composed of at least two gear sets, each gear set is of a speed reducing and torque increasing structure formed by meshing a few-tooth driving tooth and a multi-tooth driven tooth, and the gear pair is used for reducing the speed and increasing the torque; according to the gear pair, at least one driving gear is matched with the rotor assembly, at least one driven gear is matched with an output shaft of the driving motor, the output shaft outputs torque with the increased torque, and the technical problems that due to mechanical loss of the driving shaft of the exhaust valve plate, the exhaust valve is slow in adjustment response and inflexible in adju
