Permanent-magnet linear synchronous motor (PMLS-M) exist the problem of normal force fluctuation, especially in the servo feeding system of high-precision CNC machine tools, the normal force fluctuation can cause the feeding table in vibration and produce resonance with other moving components of the servo feeding system .Analysis shows that detent force fluctuation is the predominant factor. Adopt the methods of end-teeth optimization combine with skew or V-skew can effectively reduce the detent force fluctuation. By using the Fourier regression analysis and limited enumeration method to calculate the optimal parameters, and applying the layered finite element analysis for simulation. The results of simulation prove that with the precondition of the thrust force loss slightly, adopt those optimization methods can reduce the normal force fluctuation significantly.

In order to minimize the detent force of permanent magnet linear synchronous motor (PMLSM) caused by end effect, a novel auxiliary poles one-piece structure is proposed. Two auxiliary poles are extended directly from two ends of the armature core. And magnetic isolation bridges are set between auxiliary pole and armature core. Compared with the conventional discrete auxiliary poles, the one-piece structure will reduce the manufacture difficulty of PMLSM with auxiliary poles and improve the reliability of linear motor.

This paper investigates the detent force modeling of a slotted iron core type vertical permanent magnet linear synchronous motor (PMLSM) for ropeless elevator applications. Variable network non-linear magnetic equivalent circuit model is established to predict the detent force of PMLSM. The topology structure of equivalent magnetic circuit is developed and the permeances are derived and calculated. The end effect of two end teeth is essential for analysis of detent force and it is focused in the modeling. Magnetic saturation of primary iron-core also be taken into account. In final some 3-D finite-element numerical calculation results are used to validate the feasibility of the proposed method.

Linear Synchronous Motor

The permanent magnet linear synchronous motor (PMLSM) has a good application prospect due to many significant advantages such as high speed, high precision, high thrust force density, simple structure, energy saving and reliable operation etc., so the research and development are of great importance. This paper mainly focuses on the key design points of a double-sided water-cooled PMLSM. According to the required thrust force, the design is given out including the basic structure parameters, winding connection methods and water cooling system. Based on the erected finite-element model, the performances such as back-EMF, thrust force, normal force, power factor and efficiency are predicted. By comparing with a single-sided PMLSM with the same specifications, it is proved that this double-sided PMLSM has lower thrust force ripple and higher thrust force density. Moreover, the net normal force of its mover is almost zero. Finally, the predicted back-EMF is verified by measurement.
