摘 要:针对电机故障诊断的特点,提出一种基于遗传神经网络(BP)进行异步电机故障检测的新方法。针对神经网络易陷入局部最小点的固有缺点,采用遗传算法(Genetic Algorithm,简称GA)对神经网络初始权值进行全局优化。实践证明该方法可以有效地实现对异步电机的故障诊断,且易于实现,有一定实用价值。 关键词:神经网络;遗传算法;故障诊断;感应电机;实验
Abstract: High-speed PM brushless DC motors have been extensively developed and employed in industry applications,due to high efficiency and high power density.Based on a developed 2.3 kW, 150 000 r/min high-speed PM brushless DC motor,studied influence of parallel and radial magnetizations on the performance of a high-speed PM brushless DC motor comparatively.It shows that parallel magnetization is better than radial magnetization.
