Recently, the discontinuous armature PM-LSM is proposed as the driving source of transportation systems. We have proposed and examined a constant load angle control without position feedback, to suppress the velocity ripple which occurs at the re-acceleration portion with the aim of achieving smooth drive of the discontinuous armature PM-LSM. This paper presents the effectiveness of a constant load angle control without position feedback in the re-acceleration portion. We also examined the re-acceleration using constant load angle control with velocity feedback, and the results were compared.
