The invention provides a distributed winding motor comprising a stator and a rotor. The pole number p of the rotor and the slot number s of the stator meet the following relational expression: p=2k and s= m*p, wherein the k and the m are positive integers; and adjacent coils of each phase are connected in series in a reversed direction to form a coil group. According to the distributed winding motor, the adjacent coils of each phase are connected in series in a reversed direction to form a coil group, so that intersection of end portions of the coils with the same phase can be avoided, the copper loss and iron loss of the motor can be reduced, and the motor efficiency can be improved. With the method of parallel winding of two strands or multiple strands of copper wires, the end portion height can be reduced, the end portion coil length can be reduced, and the motor efficiency can be improved. With a plurality of neutral point, a phenomenon that one same welding point has too many wire heads during parallel winding of the two strands or multiple strands of copper wires can be avoided, so that the difficulty of manufacturing of the motor can be reduced and a wire head welding error can be eliminated.
