【摘要】 利用COMSOL软件,模拟了将矩形铝盘插入电磁铁(EM)与圆形铝盘(CAD)之间情形下圆形铝盘中的感应电流分布。仿真结果表明,原型的驱动转矩来自于两个安培力的转矩差。如果矩形铝盘未插入电磁铁和圆形铝盘之间,则圆形铝盘中对称涡旋电流是导致其垂直运动的原因。更多还原

【Abstract】 With help of COMSOL software the induced current distribution in circular aluminum disc is simulated when the rectangular aluminum disc is inserted between the electromagnet(EM) and circular aluminum disc(CAD).The simulated results show that the driving rotation torque of the prototype originates from the torque difference of two Ampere forces.If the rectangular aluminum disc is not inserted between the electromagnet and the circular aluminum disc,the simulated symmetric eddy currents of circular aluminum disc are responsible for its vertical movement.更多还原
