An automobile automatic transmission with a double-rotor structure, comprising an internal rotor (1), an external rotor (2), a right end cover (3), a left end cover (4), bearings (5) and collecting rings (6), wherein the internal rotor (1) is connected with an output shaft of an engine, and the external rotor (2) is connected to an input shaft of a main speed reducer. The automobile automatic transmission is characterized in that the external rotor (2) is formed by processing entity steel and can bear a large torque; two-phase excitation windings at intervals are evenly arranged on the internal rotor (1); the collecting rings (6) have four lines and are respectively connected to two full bridges of a controller for outputting, and not only can a constant magnetic field be formed on the internal rotor (1) by inputting direct currents, but also a positive and negative rotating magnetic field can be formed by inputting two-phase alternating currents with a phase difference of +/−90 degrees. The problem that the automobile automatic transmissions are high in manufacturing cost and small in speed change range is solved, and the automobile automatic transmission is suitable for various automobiles using gasoline engines and diesel engines as power.
