magnet winding meaning in Chinese

电磁绕组
电磁铁绕组
电磁铁线圈

These direct current ( dc ) permanent - magnet wound field servomotors range from 3 , 000 revolutions per minute ( rpm ) to less than 1 rpm without stalling
这些直流永磁铁将使补助马达间接变速装置从每分3000转降低到每分1转，并无延迟。
Today , mw wind generators substitute 600kw generators gradually and become the popular units of international market of wind power generation . the trends of units are variable speed constant frequency and large - scale and pitch control . there are many different generators which are variable speed constant frequency generator . in this paper the unit is fully - fed magnet wind turbine generator . the magnet wind turbine generator grid - connected inverter is the key component of connected system . the main function of this component is inverting the dc to three - level volage and connecting the electric net
实现变速恒频发电的方法众多,本文研究的是较常用的一种方案。该方案采用直驱永磁风力发电机通过变频器直接连接到电网。永磁风力发电机并网逆变器是并网发电系统的核心部分,其主要功能是将经过整流、斩波升压后的直流电逆变成三相交流电,并送入电网,实现并网。
