PURPOSE: A stator of a motor is provided to improve performance of the motor and reduce noise of the motor by forming magnetic flux distribution within a gap between a stator and a rotor as a sine wave and reduce material cost by reducing length of an end coil. CONSTITUTION: A stator of a motor comprises a core having many protruded winding parts(51A) and slots(51B) between the winding parts(51A), and coils(53) arranged around the winding parts(51A) of the core. The winding parts(51A) are formed to have their widths different from each other to make magnetic flux distribution within a gap between the stator and a rotor as a sine wave. Each coil(53) is wound around a corresponding winding part(51A) as a concentrated wound. A pattern having a thickest winding part(51A) at the center and remaining winding part(51A) of decreasing widths are repeated. The concentrated wound reduce the entire length of the coil(53) and end coils than a distributed wound case.
