“…Designed active magnetic bearing shape consists of graphical primitives like lines, arcs with fixed properties. Gazo [2]is proposed an effective control law for the stable operation in levitation mode because these devices in nature are need to unstable. In stabilizing controller has to generate the appropriate value of electromagnetic force to holding an object.…”

High speed machining technology is an important trend of advanced manufacturing engineering because of its accuracy. Spindle used in high speed machinery are capable of operating at high speed. As the spindle rotates at high speed, heat is generated in the contact area between the bearings and spindle. This heat generation leads thermal deformation and results in inaccuracy during machining. To avoid the heat generation non-contact bearing like active magnetic bearing (AMB) has been used. The main limitation in active magnetic bearing is its large size. In view of this, an attempt has been made to design and analysis of active magnetic bearing to reduce size complexity. In this paper we have mainly focused on the leg geometry effect and size of the active magnetic bearing. ANSYS workbench tool is used to analyse the flux density in pole area and calculate the maximum load carrying capacity of the bearing.
