| 摘 要： | 针对传统2-D数字阀用电-机械转换器转动惯量大、动态响应低的不足,研制了一种空心杯转子结构的低惯量旋转电磁铁.通过磁路解析讨论了电磁铁结构和运行参数对输出力矩的影响；基于Ansoft/Maxwell 3-D平台对其矩角特性进行了有限元模拟.试验结果和仿真结果基本一致,该低惯量旋转电磁铁具有较大的静力矩,其矩角特性近似于正弦波形,可用作高频2-D数字阀的电-机械转换器.

| Abstract: | Since conventional electro-mechanical converter of 2-D digital valve had limitations of large inertia and low dynamic response,a low inertia rotary electromagnet with coreless rotor structure was proposed.Based on magnetic circuit approach,the influence of key structure and operating parameters on the output torque of electromagnet was discussed firstly.Then the finite element simulation of torque-angle characteristic was performed on the platform of Ansoft/Maxwell 3-D.The experimental results were in a clo... |
