The normal forces of a single sided high temperature superconducting linear synchronous motor (SLSM) have been investigated at 77 K. The SLSM consisted of a superconducting coil made of YBCO coated conductor as the excitation system and a conventional three phase copper wound armature as the stator with a gap of 10 mm in between. Alternating current up to 7.5 A at 10.5 Hz was applied to the armature...
