The invention belongs to the technical field of helicopter motor reducer integrated design, and particularly relates to a motor coaxial reducer integrated structure. Comprising a motor, a coaxial speed reducer, a motor controller, a lubricating oil pump, a radiator and a bolt assembly, the coaxial speed reducer drives an upper rotor shaft and a lower rotor shaft to coaxially rotate reversely at a constant speed through a one-to-two bevel gear, and the coaxial speed reducer is supported by a main case and a lower case; the upper bevel gear wheel, the lower bevel gear wheel and the tapered roller bearing are compressed and fixed on the upper rotor shaft and the lower rotor shaft through a locking nut and a lock washer; the main case input side flange is connected with the motor shell through a bolt and nut assembly and provides support for the motor stator and the shell, and the bearing supporting cover plate is connected with the motor shell through the bolt and nut assembly. The lubricating oil pump supplies oil to the speed reducer, the motor stator winding and the motor controller for lubrication and heat dissipation; a lubricating oil pool is arranged at the bottom of the lower casing; the motor controller is attached to the bearing supporting end cover on the right side of the motor in the circumferential direction, and the radiator is attached to the motor controller.
