Permanent magnet linear synchronous motor(PMLSM), which uses system resources as a permanent magnet, has a high thrust-to-weight ratio and thus is capable of high-speed and high-thrust operation in the linear motion system. Though the PMLSM has been suggested for use in the field of long-distance transport system due to this feature, it has a problem of material costs and production time increasing in proportion to the distance because of the characteristics of linear motors that the armature needs to be installed on the full length of the transport path. In order to solve this problem, an armature distribution system which has the armature installed only on acceleration and deceleration parts is proposed, to reduce the material cost and production time. However, the stationary discontinuous armatures system does not have armatures in the parts where acceleration/deceleration of the mover is not required and thus, due to its structure, there must be ends of the armatures. The armature ends significantly increases the detent force that acts as a cause of vibration and/or noise from the armature, lowering the device performance. Inspired by the shape of the double auxiliary teeth, we proposed arc-shaped auxiliary teeth that could represent the change of air-gap gradually while maintaining a simple structure of the conventional auxiliary teeth. In addition, we completed the optimal design by designating each variable for effective application of the arc-shaped auxiliary teeth.
For designing the new auxiliary teeth, Taguchi’s design of experiment was used, with which the impact of each factor on the objective function were analyzed and a model suitable for reducing the end detent force was derived. Each model was numerically analyzed using finite element method (FEM) based on 3-D numerical analysis.
