| 摘 要： | 永磁直线电机能够满足电磁弹射系统短距内高加速与快制动的应用要求,但是永磁直线电机的快速运动可能引入明显的涡流效应,在电机加速度段,涡流效应引入涡流阻力,削弱了系统的弹射能力,另一方面,在电机的制动段,涡流效应引入的阻力可以帮助系统实现快速制动.针对电磁弹射系统所采用的定子开槽、集中绕组、动磁式永磁直线电机,仿真分析了动...

| Abstract: | Permanent magnet linear motors are fit for the application of quick acceleration and braking within short distance in electromagnetic aircraft launch systems,but eddy current is likely to be induced by its quick moving.In the acceleration stage,the resistance force deduced by the eddy current can reduce the launch ability of system.On the other side,the force deduced by the eddy current can improve the braking ability in brake stage.This study analyzed the eddy current force in a kind of linear motor with o... |
