Abstract Reluctance forces are the main cause of vibration in electrical machines. The influence of magnetostriction is still the matter of controversy. In the article, program Ansys (typical for finite element method) was used to analyze stator deformation due to magnetic forces (Maxwell and magnetostriction) for the different boundaries and different methods by taking into account the windings in the mechanical model. Different parameters of numerical model are important factors affecting the level of magnetostriction deformation.

BLDC 电机磁致伸缩现象有限元建模中的新元素

摘要 磁阻是电机振动的主要原因。磁致伸缩的影响仍然是有争议的问题。在文章中，通过考虑机械模型中的绕组，使用程序 Ansys（典型的有限元方法）分析不同边界和不同方法的磁力（麦克斯韦和磁致伸缩）引起的定子变形。数值模型的不同参数是影响磁致伸缩变形程度的重要因素。
