摘要
运用有限元法,对同轴圆筒式磁力耦合器的涡流特性进行了分析。模拟出涡电流对磁场的影响,这种影响主要体现在:减弱了磁力耦合器的磁场强度,并使磁耦合力矩减小了,从而造成了功率损失;针对此现象提出了减小涡流功率损失的具体方案。
The eddy characteristics of the coaxial cylindrical magnetic coupler is analyzed by using the finite element method,and the impact of eddy currents on magnetic field is simulated.These effects mainly reflected in weakening the magnetic coupling of the magnetic field intensity and reducing the magnetic coupling torque.In addition,the eddy current power loss is calculated,and specific programs to reduce the eddy current power loss is proposed.
