Lunar dynamo Scientists may have solved one of the Moon's enduring mysteries: why there are magnetised rocks on the lunar surface, when the Moon has no global magnetic field.

科学家可能已解开了一个存在多时关于月亮的谜团：为什么月亮没有全球性的磁场，而月球的表面还会有磁石的存在。

With the power being DC, the current of inner winding of the magneto is AC, and the rotating part is just similar to the magnetic rotor of synchronous dynamo.

无刷直流永磁电机的电源虽是直流电，但其内部绕组中的电流仍是交流电，其旋转部分犹如同步电机的磁极转子，其结构及电磁原理与同步电机相似。
