2.交流发电机的工作原理交流发电机产生交流电的基本原理就是电磁感应原理。当转子转动时,定子绕组与转子绕组之间作相对运动,使其磁力线切割定子线圈,在线圈内产生交变感应电动势。若转子不停地旋转,则感应电动势和负载中电流的方向和大小将随时间作周期性变化,于是 2. The working principle of alternator Alternator AC generator to generate the basic principle is the principle of electromagnetic induction. When the rotor rotates, the relative movement between the stator windings and the rotor windings causes the lines of magnetic force to cut the stator windings, generating alternating induced electromotive forces in the windings. If the rotor is constantly rotating, the direction and magnitude of the induced electromotive force and the current in the load will periodically change over time, so
