English-Chinese/Electric machine

In electrical engineering, electric machine is a general term for machines using electromagnetic forces, such as electric motors, electric generators, and others. They are electromechanical energy converters: an electric motor converts electricity to mechanical power while an electric generator converts mechanical power to electricity. The moving parts in a machine can be rotating (rotating machines) or linear (linear machines). Besides motors and generators, a third category often included is transformers, which although they do not have any moving parts are also energy converters, changing the voltage level of an alternating current.

在 电气工程中，电机 是 使用 电磁力的 机器 的 总称，例如 电动机，发电机 等. 它们 是 机电能量转换器：电动机 将 电能 转换为 机械能，而 发电机 则 将 机械能 转换为 电能. 机器中的 运动部件 可以 是 旋转的（旋转机器）或 线性的（线性机器）. 除了 电动机 和 发电机，第三类 通常 包括 变压器，虽然 它们 没有 任何 运动部件，但 也是 能量转换器，改变 交流电压.
