原料（铁，钢，磁铁，稀土，铜等）

Motion control and motor components are made from a wide variety of materials. In their raw, unfinished form, these materials often include iron, copper, steel, rare earths, and magnets.

Iron, copper, and steel are used in a wide variety of automation devices. Rare earths and magnets are as well, but they are used most often in motors, which require permanent magnets and electromagnets.

永磁体在没有任何外部影响的物体上施加力。一些永久磁铁自然地发生，例如铁矿石磁铁矿，而其他永磁体可以通过使某些材料进行磁力来制造。当除去力时，这些材料保留了它们自己的磁性。

Electromagnets are made by surrounding certain materials with a coil of wire. When an electric current is passed through the coil, these materials exert a magnetic force. When the current is shut off, the magnetic force of these materials drops to nearly zero.

Rare earths are mined elements used to create small but powerful permanent magnets and electromagnets. These rare earth magnets are in high demand as they possess a stronger magnetic pull than other magnetic resources and enable greater performance in a lighter, more compact design.
