本发明系以「高亮度LED灯」代替「电动机线圈」的创新概念，制造一个「LED电动机模型教具」。利用LED发光的颜色，显示电动机线圈通电后，所产生磁场的极性与方向。再以电路控制LED灯的亮灭，产生类似广告灯的旋转视觉效果，藉由LED色彩的变化可吸引学生注意，提高学动机。本发明利用「手动操作」的模式，将旋转电机「连续」快速的动作方式，分解成「离散」步阶的手动操作模式。使学生由一步一步手动的操作过程，观察LED灯颜色的亮灭变化，体会出电动机建立旋转磁场的工作原理。 The invention will create a “new design LED motor teaching device” based on the innovative concept of substituting LED for coil inside the motor. The color of LED lights indicates the pole and direction of the magnetic field. With a control circuit to manipulate the LED lights, we can create visual effects that simulate the spinning motion of electromagnetic fields inside a motor. The colorful blinking LED light, resembles the neon sign, can attract students' attention easily and boost their learning motivation. This device will break down the “continuous” rapid action of rotating electrical machinery, into a “discrete”
