Abstract
A stator coil of a slotless motor is disclosed in which the stator coil is formed in such a manner that respective both distal ends of two unit coil bodies, each unit coil body arranged to face each other, are respectively coupled to form a plurality of circular coil bodies, each circular coil body having a different inner diameter, and a circular coil body having a smaller inner diameter is sequentially inserted into an inner side of a circular coil body having a larger inner diameter, whereby a horizontal width of the plurality of unit coil bodies of U, V and W phases is equal there among to cause the strength of the magnetic field of U, V and W phases to be equal, and to allow the stator to be accurately manufactured, thereby catering to a designer's intention and markedly simplifying the assembly processes.
