The present invention relates to a double stator and a motor comprising same, which enables devising a stator having high-output, high-speed, high-efficiency, and a slim structure by configuring a hybrid-type stator core to combine in a way that supplements the disadvantages and accentuates the advantages of a stackable core and a compressed powder integrated core. The double stator comprises: a stator core; a bobbin surrounding the outer circumferential surface of the stator core; and a first coil wound on one side of the stator core and a second coil wound on the other side of the stator core, wherein the stator core comprises a stackable core portion, which is formed by stacking a plurality of iron pieces, and forming a first indentation groove on the outer surface and a second indentation groove on the inner surface, a first integrated core portion which is fixed to the first indentation groove on the stackable core portion, is integrally formed by means of a metal powder, and on which the first coil is wound, and a second integrated core portion which is fixed to the second indentation groove on the stackable core portion, is integrally formed by means of a metal powder, and on which the second coil is wound. |
