Abstract
Provided is a stacking-type stator using a multilayer printed circuit board (PCB) in which torque generation can be maximized in an opposite rotor, and a single-phase motor and a cooling fan both using the same. The stacking-type stator includes: a multilayer printed circuit board (PCB) that is stacked and integrated with a penetration opening; and a coil pattern patterned on each layer of the multilayer PCB, wherein throughholes are formed to penetrate the multilayer PCB and connect the coil patterns, wherein the coil pattern comprises: inner and outer rotating direction pattern portions which are arranged in a circumferential direction at intervals along an inner circumference and an outer circumference concentrically with the penetration opening; and a radial pattern portion that interconnects the inner rotating direction pattern portion and the outer rotating direction pattern portion that are adjacent to each other and is disposed along the radial direction.
