The invention discloses a stator module for a motor and a single-phase asynchronous motor with the stator module. The stator module comprises a stator iron core, wherein the stator iron core is provided with a stator hole; a plurality of stator teeth which is arranged along the circumference of the stator hole at interval is arranged at the peripheral edge of the stator hole; a wire wrapping groove is limited between any two adjacent stator teeth; in any two imaginary lines which are located at the cross section of the stator core and which pass through the centre of the stator hole and are vertical to each other, if one imaginary line passes through and equally divides one stator tooth, the other imaginary line passes through and equally divides one wire wrapping groove; a stator winding, wherein the stator winding is arranged in the wire wrapping groove, and the slots per pole Q1/2p of the motor are odd number, wherein the Q1 represents the number of the wire wrapping groove, and 2p represents the number of poles of the motor. According to the embodiment of the invention, the number of the windings needed by generating same magnetic field with the stator module is reduced, and the electric efficiency is improved. The stator module is convenient for manufacturing and could be applied to a manufacturing method in relative technology, and the manufacturing costs will not improve.
