Abstract: This invention relates to a motor stator device comprising a stator, a plurality of coils, and a rotor. The stator includes a plurality of serrate portions, and a positioning slot disposed between two serrate portions at an internal wall of the stator, and each positioning slot having a tooth; each coil being wound around each serrate portion in the stator and disposed inside the rotor for producing an electromagnetic attraction when the coil on the stator is connected electrically, so as to drive the rotor to rotate, and enhance the area occupying percentage and the performance of the conducting wire and lower the detention torque without affecting the rigidity of the motor.
