The influence of the leading Angle (lagging Angle) of the current reference signal the parameters and drive mode of the system to the dynamic characteristics are analyzed.

With the measured ratio and lagging Angle, in the process of field balancing for high speed grinding, the rotor system can attain quick balance just adding balancing mass one time.

In the condition of eliminating the lagging strain of Angle iron, the magnitude of pre-stress putting on the Angle iron has litter impact on the ultimate bearing capacity of structure.
