Abstract :
Summary form only given. This paper introduces the design and development of an axial-gap spindle motor using printed circuit boards (PCBs) and dual air gaps, which meet the mechanical rigidity, high efficiency and zero cogging torque required in a computer hard disk drive. Performance of the developed motor is experimentally compared with the conventional radial-gap spindle motor. Experimental results show the possibility that the developed motor can be used effectively for various disk drives with manufacturing flexibility.
