A magnetic suspension guiding direct-driven transportation system comprises at least one set of double-sided hybrid excitation linear motor. Each set of the double-sided hybrid excitation linear motor is provided with an electromagnetic drive guiding device used for adjusting an air gap between a double-sided stator and a rotor, the electromagnetic drive guiding device comprises a deviator acquisition circuit, a winding current detection circuit, an air gap adjusting unit and a driving control unit, and controls the air gap adjusting unit according to obtained offset and exciting current value, and therefore the air gap adjusting unit satisfies following conditions that the arithmetic product of each DC exciting current value and the number of turns of excitation coils, namely the excitation magnetic potential is identical or approximately identical, due to the directions of two exciting currents and the winding directions of coils, when the excitation field and the normal force at one side are enhanced, the excitation field and the normal force at the other side are decreased, and the total electromagnetic force is identical or approximately identical before and after the exciting currents are introduced. By employing the scheme provided by the invention, the left and right, and back and forth postures of the rotor are adjusted dynamically in balance, and the rotor can operate in a contactless manner.
