Rotor Dynamic Analysis Applicable to Vertical Axis Wind Turbine

M S Patil | Tofiq I G

Abstract: Requirements and the Demands for sustainable energy have results in increased interest in wind mill or wind turbines. Thus, despite widespread economic difficulties, global installed wind power which is increased by over 20% in 2011 alone [1]. Recently the magnetic bearing technology has been proposed to improve the wind turbine performance by mitigating vibration in shaft and bearing to reducing frictional losses. While magnetic bearing has been used to reduce friction in other applications, little data has been presented to establish magnetic effect on vibration and friction in wind turbines. Accordingly, this study provides a functional method for experimentally evaluating the effect of a magnetic bearing on the vibration and efficiency characteristics of a wind mill, along with the associated results and conclusions. The magnetic bearing is used is a type of passive magnetic bearing, The design of concentric rings and it's vibrational behavior, and the dominant parts of frequency, and results of efficiency are tabulated for the bearing are to be tested in two systems in that a precision test by fixtures, and a small economical use of commercial available wind mill or wind turbines. Data of the equivalent of ball bearings are compared with magneto type, also providing a reason behind the advantage of the magnetic type of bearings with respect to their performance and efficiency [2]. There are wide range of requirements of magneto type bearings due to ease of lubricating system which needs the extra parts like pump, in hydrostatic and also the lubricating oil.
