The invention discloses a shellless shaftless high-pressure high-speed starting power generation device for aero-engines. The shellless shaftless high-pressure high-speed starting power generation device comprises a shellless stator assembly 3, a shaftless rotor assembly 2 and a rotating speed sensor assembly. The shellless stator assembly is arranged on a dedicated inner wall between an engine case 1 or an air compressor outlet and a combustion chamber. The shaftless rotor assembly 2 is free of a bearing, and is arranged on an engine shaft 5, the shaftless rotor assembly 2 is powered by an externally provided power source to generate electromagnetic torque to drive the engine shaft 5 to rotate during starting, when the given rotating speed is reached during starting, the state is converted to a power generation state through a controller, and the engine shaft 5 drives the shaftless rotor assembly 2 to rotate to generate power. The power generation quality is adjusted through the controller, and a monitoring
