Force Analysis of Single Axis Actuator Used in Active Magnetic Bearing (AMB)

Abstract

This paper presented the force analysis of single coil actuator for Active Magnetic Bearing (AMB) system. Actuator is the most important segment of AMB system. In the bearing system rotor should be levitate before rotation. For the levitation required force is generated by actuator. For the specific structure attractive force is different. These force analysis is done in this manuscript. Depending upon the force appropriate structure can be used for design a perfect AMB system. Here force analysis is performed in ANSYS Maxwell software and characteristics graphs are presented in 2D and three dimensional plots are constructed using MATLAB for the better observation.
