This paper deals with the performance characteristics of a two-axis linear pulse motor (X-Y LPM) using air bearing. The mass, M, of the mover of X-Y LPM is 1.35 kg and the maximum static thrust, F_s, is 48.5 N with two-phase excitation at 2 A. The maximum velocity of the mover, v, is 1.4 m/s and the maximum acceleration, a, is 14.3 m/s^2 at a velocity of 1 m/s without any load. The kinetic thrust, F_k, 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, B_m, 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 X-Y LPM.
