Rotating electric machine

Japanese: 回転電気機械 - かいてんでんききかい（英語表記）rotating electric machine

Electrical machines are divided into those that convert mechanical energy into electrical energy and those that convert electrical energy into mechanical energy, and those that pass electrical energy through. Depending on the form of energy conversion, they are further divided into those that have rotating parts and those that do not. Those that have rotating parts, such as generators and motors, are called rotating electrical machines.

電気機械は機械的エネルギーを電気エネルギーに，電気エネルギーを機械的エネルギーに変換するものと，電気エネルギーを通過させるものに分れる。さらにエネルギー変換の形態により回転部分をもつものと，もたないものとに2分される。発電機や電動機のように，回転部分をもつものを回転電気機械と呼ぶ。
