Abstract
The described technology relates to a stator of a planar type motor and a planar type motor using the same, which are easy to manufacture and are capable of reducing core losses, thereby maximizing motor performance. First cores that are difficult to form by stacking electrical steel plates are formed of soft magnetic powders, and second cores that are formed by stacking electrical steel plates having the same size are arranged in a region where a vortex is concentrated, thereby allowing easy manufacture and being capable of maximizing the performance of the planar type motor.
