WIPO Patent Application WO/2020/184860

A3

Disclosed are a coil assembly of a slotless motor, a housing, and a slotless motor including same. According to the present invention, provided is a coil assembly of a slotless motor, the coil assembly comprising: a plurality of first coil assemblies facing each other with a first space therebetween, wherein each of the first coil assemblies has a cross-section having two sector-shaped first coil sides in the width direction, and has a first end turn curved in a first direction from at least one longitudinal end of the two first coil sides; and a plurality of second coil assemblies facing each other with a second space therebetween, wherein each of the second coil assemblies has a cross-section having two sector-shaped second coil sides in the width direction, and has a second end turn curved in a second direction from at least one longitudinal end of the two second coil sides. The plurality of first coil assemblies and the plurality of second coil assemblies are coupled to each other, thus forming a circular stator winding structure.
