摘要
法拉第电动机使用电刷改变流经转子线圈中电流的方向,若无电刷的情况下法拉第电动机似乎不能维持转动.事实上无电刷法拉第模型电动机在人为给转子线圈初始角动量的情况下却可以不停地转动.提出了转子线圈转轴跳动假设,给出无电刷法拉第模型电动机转动的动力学解释,并得到实验验证.
The Faraday motor,in which brush was used to change the direction of the current in the windings,seemed unable to rotate without brush.However,the brushless motor could rotate and give continuous power output if an initial push was given.We presented a hypothesis of pulsation of the motor＇s rotor shaft to explain the dynamics of brushless Faraday motor,which was verified by experiments.
