The smaller interval is the larger power output is . so in order to be the largest power output , the structure should be as small as possible . as far as the instantaneous heating electromagnetism vortex water heater is concerned , the power which the excitation device outputs is too small , so we adopt two e 又由于对于即热型电磁涡流热器来说，单个励磁装置输出的功率过小，达不到加热的目的，因而木电磁涡流热水器采用两套励磁装置，进行双面加热，每块涡流加热扳的两表面均有水流过，即整体上采用双面加热，四面过流的结构方式。

The analysis and research of the starting and running of the synchromotors iii many large pumping stations and the working condition of excitation system have indicated that the causes leading to damage to the motor or difficulties in starting are relevant to the poor technical characteristics of the equipped excitation system , especially resulting from the frequent restarting after failure to start the motors and the failure to protect or protect the synchromotors improperly in the fall - out 通过对大泵站同步电机起动、运行及励磁装置工作状况的分析和研究，结果表明：导致同步电机损坏及起动困难的原因与电机所配励磁装置保护技术性能不完善有关；特别是先期起动失败后再多次频繁起动及运行失步时未起保护作用或保护不到位造成。
Thus , it is difficult to find the voltage reference for the harmonic analysis . since acem are always operated near to the synchronous speed , the frequency of the excited voltage is very low , even to zero . therefore , this is the power harmonic suppression study of a complicated power supply system , in which the about harmonic general theories and methods are all inapplicable 现代交流励磁电机( acem )采用电力电子变流器作为励磁装置，其励磁电压谐波含量丰富，难于获得谐波分析所需的电压基准，同时交流励磁电机经常工作在同步转速附近，致使励磁电压频率极低甚至为直流，通常的谐波检测方法和理论都无法适用，因而这是一种目前尚未深入探讨过的复杂供用电系统电力谐波抑制问题的研究。
