Stator for synchronous motor

Abstract

A stator for a motor that includes an armature coil that generates an N-pole and an S-pole by applying a current and forty-eight slots radially formed at which the coil is disposed and in which the armature coil alternately implements N-poles and S-poles by arranging six slots as a single unit as the current is applied to the coil. The slot includes a plurality of phase drawing out slots, and when the order of the phase drawing out slots is determined in a clockwise direction by setting one phase drawing out slot as a first phase drawing out slot, at least two methods of winding the armature coil to turn around the slot may be used to decrease a distance from the first phase drawing out slot to the last phase drawing out slot to a minimum value by setting a cell between neighboring slots as a unit.
