串励式无轴承开关磁阻发电机的悬浮力特性研究
|
摘要
串励式无轴承开关磁阻发电机(BSRG)的稳定悬浮发电取决于对各绕组电流的合理控制,而在其运行状态和负载情况相同时,电流又取决于绕组电感和悬浮力,因此二者的准确计算是设计和控制该电机的关键。建立了串励式BSRG的二维有限元模型,计算了悬浮绕组电感。结合实际控制策略,在不同磁动势组合下,研究了串励式BSRG的悬浮力特性。
The suspended operation of bearingless switched reluctance generator( BSRG) with the adjacent three excitation- windings connected in series depends on the control of currents in windings,and currents in windings rely on calculations of its inductance and radial force,so computations of radial force and inductance are the key to design and control this machine. The 2D model of the BSRG was set up,and its inductance of suspended winding was calculated. Moreover,based on its control strategy,the characteristic of radial force was studied on condition of different magnetomotive forces.
