Permanent magnet type linear synchronous motor (PM-LSM) that is utilized for the discontinuous primary has been proposed to satisfy the requirements include the speeding up the transportation system and simplifying the maintenance as a result, synchronization and a positioning method are established. However, velocity pulsation of the secondary occurs when the secondary mover overlaps with the primary section. This paper describes the examination of constant load angle control without position feedback with the aim to suppress the velocity pulsation, which happens in the re-acceleration part.
