This paper deals with the performance characteristics of a two-axis linear pulse motor (<i>X-Y</i> LPM) using air bearing. The mass, <i>M</i>, of the mover of <i>X-Y</i> LPM is 1.35 kg and the maximum static thrust, <i>F</i><sub>s</sub>, is 48.5 N with two-phase excitation at 2 A. The maximum velocity of the mover, <i>v</i>, is 1.4 m/s and the maximum acceleration, <i>a</i>, is 14.3 m/s<sup>2</sup> at a velocity of 1 m/s without any load. The kinetic thrust, Fk, is 19.3 N. A non-oriented magnetic steel sheet, 50A350, is used as the core in the mover, and rolled steel for general structures, SS400, is used as the stator. The maximum flux densities, <i>B</i><sub>m</sub>, of 50A350 and SS400 are 1.45 T and 0.123 T, respectively, in a magnetic field with a maximum intensity of 1 kA/m and at a frequency of 1 kHz. The material of the stator must have a high magnetic flux density at the driving frequency to achieve high velocity and high-thrust driving of the <i>X-Y</i> LPM.
