Abstract:
Provided is a stacking-type stator including: a multi-layered substrate; coil patterns formed in a helical shape to form a plurality of turns on respective substrates of the multi-layered substrate and interconnected through conductive throughholes; a Hall sensor disposed in the multi-layered substrate and disposed at a position deviated from an interface of a magnetic pole of a rotor; and a dead point prevention yoke for setting the position of the rotor such that the Hall sensor is positioned at a position deviated from the interface of the magnetic pole of the rotor. The helical shape coil patterns include: radial direction pattern portions each disposed along a radial direction to generate a torque to rotate the rotor; and inner and outer connection pattern portions that interconnect the radial direction pattern portions and the coil patterns form a stator coil for a single phase motor.
