摘要:

通过有限元法对一种混合式单边型结构的直线步进电机的若干关键参数进行优化分析.采用有限元法研究了该结构电机在体积一定条件下绕组控制电流和气隙大小对电机切向力、法向力的影响,得到了相应的关系曲线;在动子、定子齿宽齿距比一致与不一致的两种情况下,计算不同齿宽齿距比时电机的切向力和单边法向力大小,并具体分析了电机静态切向力的谐波状况,得到两种情况下最大保持力和最大基波推力所对应的齿宽齿距比.结果表明:当动、定子齿宽齿距比在0.33~0.38时可使切向力及其基波分量较大且法向力较小,其中在0.36左右时,电机的基波推力最大.

Abstract:

Some key parameters of a single-sided hybrid linear stepping motor (HLSM) were analyzed for optimization by finite element method (FEM). The influence of the winding current on the normal force and the tangential force was studied by FEM with a certain machine volume, as well as that of the distance of the air-gap between mover and stator, and the relationship curves were given respectively. The characteristics of force-displacement with different tooth width/tooth pitch ratios were calculated to find out the optimum ratio for the maximum thrust and a lower normal force. The harmonic waves of the tangential thrust were analyzed by FFT in different ratios of tooth width/tooth pitch, which were conducted when the ratio of the forcer and that of the stator were equal and unequal respectively. The result shows that the range between 0.33 and 0.38 is preferable for the ratio of tooth width/tooth pitch to increase the thrust and its fundamental part while suppress the normal force, the favorable ratio of tooth width/tooth pitch is about 0.36 to obtain the maximum static thrust.
