【摘要】：针对永磁涡流联轴器调速结构复杂的问题,结合自励发电和涡流传动技术,提出一种新型自励式电磁涡流联轴器结构。通过建立自励发电和电涡流传动两部分的电磁场有限元数值模型,研究了自励式电磁涡流联轴器的发电特性和传动特性。通过对转速差、导体层和气隙长度对传动力矩影响的分析可以看出:转速差较小时,导体层选择电导率高的材料可以得到较大的力矩;铜层厚度由1mm增大到9mm时,传动力矩先增大后减小,在铜层厚度为5mm时达到最大;传动力矩随气隙长度增大而减小。
[Abstract]:Aiming at the complex speed structure of permanent magnet eddy current coupling, combined with self-excited power generation and eddy current drive technology. A new structure of self-excited electromagnetic eddy current coupling is proposed. The electromagnetic field finite element numerical model of self-excited generation and eddy current drive is established. The power generation characteristics and transmission characteristics of self-excited electromagnetic eddy current coupling are studied. Through the analysis of the effect of rotational speed difference, conductor layer and air gap length on transmission torque, it can be seen that the speed difference is small. When the conductor layer chooses the material with high conductivity, a large torque can be obtained. When the thickness of copper layer increases from 1 mm to 9 mm, the transmission torque increases first and then decreases, and reaches the maximum when the thickness of copper layer is 5 mm. The driving torque decreases with the increase of air gap length.
