Fem software based 2-D and 3-D construction and simulation of single and double coils active magnetic bearing

Abstract

This elaboration offers a dynamic model of an Active Magnetic Bearing (AMB) simulated in ANSYS Maxwell 17.1. This work reports simulation for two distinctive structure of AMBs that utilizations single electromagnets and double attraction type electromagnets put in 180 degrees separated from each other. At first, the theoretical model of single coil AMB and double coils AMB has been presented. It also deals with a simulation study of active magnetic bearings utilizing Finite Element Method (FEM) in two-dimensional (2-D) and three-dimensional (3-D) platform. 2-D and 3-D simulation have been compared for single and double coils AMB system. Magnetic properties such as-force, magnetic, flux pattern and flux density are performed and observed utilizing ANSYS Maxwell simulation software. This paper also includes a comparative study of an AMBs system with the variation in the gap between the actuator and the rotor and the effect of variation in inductance, flux, magnetic field and force are detected which is obligatory for hardware execution of an AMB system.
