Abstract

Purpose The aim of this paper is to introduce an accurate asymmetric fault index for the diagnosis of the faulty linear permanent magnet Vernier machine (LPMVM). Design/methodology/approach Three-dimensional finite element method is applied to model the LPMVM. The geometrical and physical properties of the machine, the effect of stator and translator teeth, magnetic saturation of core and nonuniform air gap due to asymmetric fault are taken into account in the simulation. The air gap asymmetric fault is proposed. This analytical method estimates the air gap flux density of an LPMVM. Findings This paper presents an analytical method to predict the performance of a healthy and faulty LPMVM. The introduced index is based on the frequency patterns of the stator current. Besides, the robustness of the index in different loads and fault severity is addressed. Originality/value Introducing index for air gap asymmetry fault diagnosis of LPMVM.

线性永磁游标机的非对称气隙故障检测

目的为线性永磁游标机(LPMVM)的故障诊断引入一种准确的非对称故障指标。设计/方法/方法采用三维有限元法对LPMVM进行建模。仿真考虑了电机的几何和物理特性、定子和平移齿的影响、铁心磁饱和和非对称故障引起的不均匀气隙等因素。提出了气隙不对称故障。这种分析方法估计了LPMVM的气隙磁通密度。本文提出了一种预测健康和故障LPMVM性能的分析方法。引入的指标是基于定子电流的频率模式。此外，还研究了该指标在不同负荷和故障严重程度下的鲁棒性。引入LPMVM气隙不对称故障诊断指标。

期刊介绍： COMPEL exists for the discussion and dissemination of computational and analytical methods in electrical and electronic engineering. The main emphasis of papers should be on methods and new techniques, or the application of existing techniques in a novel way. Whilst papers with immediate application to particular engineering problems are welcome, so too are papers that form a basis for further development in the area of study. A double-blind review process ensures the content''s validity and relevance.
