同步电机的主要励磁方式：
（1）直流励磁机励磁 其组成为：直流副励磁机+直流主励磁机+主发电机 其特点为：需要的电刷、换向器或集电环的组数较多，现多用于中、小容量的发 电机。
（2）静止整流器励磁 其组成为：交流副励磁机+交流主励磁机+主发电机 其特点为：仍然需要一定数目的电刷和集电环，现应用范围较广。
（3）旋转整流器励磁 其组成为：交流副励磁机+交流主励磁机（转枢式）+主发电机 其特点为：不需要电刷和集电环，是一种比较新颖的励磁方式。
（4）自励 其组成为：没有励磁机，主发电机发出的电的一部分经整流后给自己励磁。 其特点为：结构简单，常用于小型同步发电机系统。

装入前，轴(轴套)、压盖应无毛刺，轴承状况良好;密封件、轴、密封腔、压盖都应该清洗干净。为减少摩擦阻力，轴上安装机械密封的部位要薄薄地涂上一层油，以进行润滑，考虑到橡胶O形圈的相溶性，若不宜用油，可涂肥皂水。浮装式静环不带防转销的结构，不宜涂油，应干式装入压盖。先将静环与压盖一起装在轴上，注意不要与轴相碰，然后将动环组件装入。弹簧座或传动座的紧定螺钉应分几次均匀拧紧。在未固定压盖之前，用手推补偿环作轴向压缩，松开后补偿环能自动弹回无卡滞现象，然后将压盖螺拴均匀地锁紧。

对于表面锈蚀，耦合效果极差的在役设备、管道等可通过砂、磨、挫等方法对表面进行处理，降低粗糙度，同时也可以将氧化物及油漆层去掉，露出金属光泽，使与被检物通过耦合剂能达到很好的耦合效果。工件曲率半径太小，尤其是小径管测厚时，因常用表面为平面，与曲面接触为点接触或线接触，声强透射率低(耦合不好)。可选用小管径专用(6mm),能较的测量管道等曲面材料。检测面与底面不平行，声波遇到底面产生散射，无法接受到底波信号。
