的保护措施现场实验（Protection）

四个风机电电风扇叶片连在共同加固受到束缚其电动机视频，比如风机及微电子插件不易影响，受到束缚电动机视频的插件被解松则风机可会自动自己加载电动机视频。（All fans have integrated protection against locked rotor condition so that there will be no damage to winding or any electronic component. Restarting is automatic as soon as any constraint component to rotation has been released。）

叶轮移动到在铅垂地理位置，使用 开关按钮“ON”或“OFF”排散热器风扇360度旋转或停机，使用正常值则描述排散热器风扇是合格证书品（As fan placed at dead angle position, and the switch of FAN was changed from off to on，Restarting was automatic normal as soon as and proved that this fan is good fan）
