The principle of the estimation is based on least square estimation under a reasonable constraint. Method is suitable to avoid using complicated test apparatus. Torque constant  static friction coefficient  vicious friction coefficient and inertia moment can be estimated. Furthermore  copper loss  iron loss  mechanical loss and other loss can be computed from these estimation and measurement data. By the proposed method  it is demonstrated experimentally that accuracy estimation can be achieved. 2012 IEEE.   New measuring technique of steel tube roundness based on CT radiographic test 期刊论文 2010, 2010 Peng Shuai-jun; Wu Hai-feng 收藏  |  浏览/下载：4/0 Circumferential strain measurement for a concrete cylinder in uniaxial compression by a fiber optic sensor 期刊论文 2010, 2010 Qingbin Li; Ansari, F. 收藏  |  浏览/下载：2/0 Closed-loop system linearity of a comb-finger micro-accelerometer 期刊论文 2010, 2010 Wu Tianzhun; Dong Jingxin; Zhao Changde; Feng Yuxiang 收藏  |  浏览/下载：3/0 FEM analysis of tubularbell pitch characteristics 期刊论文 2010, 2010 Zhao Bonan; Zhao Haiyan; Xing Hao; Han Baoqiang 收藏  |  浏览/下载：5/0 Research of tortional tunneling magnetometer designing method 期刊论文 2010, 2010 Yan Meizhi; Dong Zhe; Ren Dahai; You Zheng 收藏  |  浏览/下载：3/0
