Abstract

 In recent years, the miniaturization of a linear motor has progressed by the chip mounter the miniaturization of a conveying machine, or the loading demand to a special use. There is a case where a smooth drive is required in it. It is important to take into account the influence of the Total Harmonic Distortion (THD) in the design of a linear motor. the THD of three magnet array were checked. At Halbach array which pursued high thrust density, the fundamental cause and effect relationship between the THD from fluctuating a Halbach array aspect ratio and the induction voltage was checked. At Cylinder Linear Synchronous Motor (CLSM) of small size (φ10) and high thrust density, I showed means to reduce the THD.
