“…The principal design of the change-step structure is depicted in Figure 1. The long stator motor sections at both sides of the guideway are installed in a staggered manner [9,14]. The overlap length must be longer than one train in length V for minimizing the thrust losses due to a stator section change.…”

The propulsion technology of long stator linear synchronous motors is used to drive high-speed maglev trains. The linear synchronous motor stator is divided into sections placed on guideway. The electric power supplies to stator sections in which the train just passes in change-step mode for long-distance operation. However, a thrust drop will be caused by change-step machinery for driving magnetic vehicle. According to the train speed and vehicle data, the change-step mode has three types of operation, namely premature commutation, simultaneous commutation, and late commutation. Each type of operation has a different thrust drop which can be affected by several parameters such as jerk, running speed, motor section length, and vehicle data. This paper focuses on determining the thrust drop of the change-step mode. The study results of this paper can be used to improve the operation system of high-speed maglev trains.

“…Typical examples are the Transrapid series in Germany [1][2][3][4] and the MLX series in Japan [5][6][7]. Both propulsion systems operate with long stator linear synchronous motors [8][9][10][11]. Although the maglev system in Germany can already go into commercial operation, the improvement of propulsion technology is still ongoing.…”

“…However, the PMLSM has been more widely used in the factory automation (FA) field such as transportation system than the existing system which uses rotation machine, and has been also used in various kinds of transportation applications for its relative high power density and efficiency [1]. According to these situations, the importance of the long-distance heavy load transportation system in PMLSM is also steadily increasing, and lots of research results are shown [2][3][4].…”

-In recent years, a permanent magnet linear synchronous motor (PMLSM) hasbeen used in various kinds of transportation applications for its relative high power density and efficiency. The general transportation system arranges the armature on the full length of transportation lines. However, when this method is applied to long distance transportation system, it causes increase of material cost and manufacturing time. Thus, in order to resolve this problem, we suggested stationary discontinuous armature PMLSM. However, the stationary discontinuous armature PMLSM contains the edges which always exist as a result of the discontinuous arrangement of the armature. These edges become a problem because the cogging force that they exert bad influences the controllability of the motor. Therefore, in this paper we proposed the combination of skewed magnets and stair shape auxiliary teeth to reduce the force by edge effect. Moreover, we analyzed the influence of the design factors by using a 3-D finite element method (FEM) simulation tool.

“…However, in order to apply PMLSM to about 200M of longdistance transportation system, armature should be placed in the full length of the transportation path. Such system is mainly applied to short distance transportation system, because initial installation cost and manufacturing time are greatly increased compared to linear induction motor [3][4][5]. Therefore, by proposing stationary discontinuous armature system that installs armature only at the region of accelerating or decelerating mover, we improved the problem of installation costs.…”

Although Permanent Magnet Linear Synchronous Motor enables high-speed and high thrust compared to rotary machine, its application to the long-distance transportation system has been delayed due to high installation costs. Thus, by proposing stationary discontinuous armature system that installs armature only at the part accelerating and decelerating mover, we improved the problem of installation costs in this paper. Also, we proposed new shape of auxiliary teeth for the armature end edge of this system to reduce the detent force causing noise and vibration of equipment and showed detent force reduction effect which was more improved than existing auxiliary teeth based on optimal design using the design of experiment.
