Abstract: One embodiment relates to a stator unit and a motor comprising same, the stator unit comprising: a stator core; a coil wound around the stator core; and an insulator disposed between the stator core and the coil, wherein the stator core comprises a support part, and a coil winding part disposed on both side surfaces of the support part so as to protrude therefrom, wherein the support part and the coil winding part are disposed so as to form a cross shape. Accordingly, a coil space factor may be increased by using the cross-shaped stator core.
