The invention discloses efficient electromechanical integrated equipment which comprises an electromechanical shell, a generator set, a motor set, a rotary shaft, a flywheel and a flywheel guard. Theelectromechanical shell is externally provided with a cylindrical shell and internally provided with the generator set and the motor set in sequence. The rotary shaft is arranged in the middle of theelectromechanical shell in a penetrating mode and provided with the generator set and the motor set. The left side of the rotary shaft is connected with the flywheel, and the outer side of the flywheel is provided with the flywheel guard in a covered mode. The flywheel guard is equal to the electromechanical shell in diameter. The efficient electromechanical integrated equipment has the beneficialeffects that the structure is simple, use is convenient, the generator set and the motor set are arranged, on the one hand, power can be provided for mechanical movement, and electric energy is converted into kinetic energy; on the other hand, the electric energy can be reserved, the electric energy is converted into mechanical energy, mutual conversion of the kinetic energy and the mechanical energy is achieved, and the efficiency is improved; and meanwhile, a cooling device is arranged, the temperature is decreased, and the service life is prolonged.
