COIL STRUCTURE FOR A CORELESS MOTOR

摘要

A coil structure for a coreless motor includes a plurality of first conductive traces and a plurality of second conductive traces. The first conductive traces are disposed in succession relative to one another, and are each arranged into a planar spiral configuration having a substantially polygonal shape. At least one adjacent pair of the first conductive traces cooperate to define a space therebetween. Each of the second conductive traces is disposed in the space defined by a corresponding adjacent pair of the first conductive traces, and is arranged into a planar spiral configuration that has one of a substantially triangular shape and a substantially rhombic shape so as to substantially fill the space.
