【技术实现步骤摘要】

技术介绍
现有的电机系统,尤其是离心设备系统调节流量和压力的方式主要有以下几种 风门挡板、阀门、液力耦合器、变频器、内反馈斩波调速。风门挡板、阀门是传统方式,可以有 效调节流量或压力,但弊端也显而易见不节能,易引起系统内的冲击。液力耦合器虽然可 以起到调节转速的作用并可以一定程度节能,但效率较低,且不够稳定。变频器和内反馈斩 波调速则是用直接改变电机转速的方式来调节系统和负载,效率较高,节能效果也不错,但 因为电器元件多,故障点多,对环境要求高,寿命周期较短,且有电磁干扰。在这种情况下,永磁调速器在电机调速领域是一个新型的理想选择;但普通的平 板转盘式的永磁调速器耦合面为平面,面积小,扭矩较小,且轴向力较大,对轴承的要求高, 易于损坏。
