制作简易电动机是“电磁联系”中一个重要的实践操作活动。虽然教材给出了直观的模型,但是实际制作起来却有一定的难度。通过合理利用器材,可以提高制作的成功率,快速、高效地完成制作,并能保证装置稳定地运行,现象明显,效果良好。 Making a simple motor is an important practice in Electromagnetic Contact. Although the textbook gives an intuitive model, it is somewhat difficult to actually produce. Through the rational use of equipment, can improve the success rate of production, quickly and efficiently to complete the production, and to ensure stable operation of the device, the phenomenon was obvious, the effect is good.
