3D A stator for coreless motor manufactured using 3D printing and coreless motor including the stator

摘要

Disclosed are a stator for a coreless motor manufactured by using three-dimensional printing and a coreless motor including the same. According to the present invention, the stator for a coreless motor comprises: a plurality of stator units of nonmagnetic materials accommodating a rotor and having teeth formed on an outer circumferential surface thereof on which a coil is wound so as to be mutually coupled; and a back yoke having an overhang structure and coupled with the plurality of stator units coupled by the coil.
