The utility model discloses a 2/6 pole duplex winding double-speed three-phase asynchronous motor, comprising two sets of stator windings corresponding to a 2 pole and a 6 pole. The 2 pole stator winding uses a Y-type connection, and the 6 pole stator winding uses a Y-type connection or a [delta]-type connection. The number of parallel paths of the 6 pole stator winding is one path or two paths. A pole phase group of a motor is arranged in a sequence of U, -W, V, -U, W, and -V. When the [delta]-type connection is used for the 6 pole stator winding and the number of parallel paths is two, for any phase of windings in the 6 pole stator winding, three anode coil groups are connected in series to form a branch circuit, and three cathode coil groups are connected in series to form a branch circuit. Through correct connection of the coil groups, the 2 pole stator winding and the 6 pole stator winding totally have eight connections to be selected, respectively are Y/Y, Y/[delta], Y/2Y, Y/2[delta], 2Y/Y, 2Y/[delta],
