Abstract

DEBNATH, S.  and  BISWAS, P. K.. Study and analysis on some design aspects in single and multi-axis active magnetic bearings (AMB). J. appl. res. technol [online]. 2021, vol.19, n.5, pp.448-471.  Epub Mar 25, 2022. ISSN 2448-6736.  https://doi.org/10.22201/icat.24486736e.2021.19.5.1211.

Active magnetic bearing (AMB) is a substitute for conventional bearing, which provides electromagnetic force to support the rotating part respecting the stator. The utilization of electromagnetic force makes this bearing “active”. The attraction force of an AMB system can be controlled by manipulating the input so that the rotor can levitate at the required position. As there is lot of limitation in passive magnetic bearings, the AMB is very useful for modern applications. Because of the frictionless nature of the magnetic bearing and the lack of necessity of lubricants, currently, AMB is taking place as the alternative for any other bearing in multiple applications of the growing industry. Adequate knowledge of essential components is necessary for the successful implementation of any active magnetic bearing design. Therefore, in this paper, a magnetic analysis has been done for the different types of single and multi-axis AMBs using ANSYS Maxwell with extensively reviewed components.

Keywords : Actuator; AMB; current controller; power amplifier; position sensor; ANSYS Maxwell.
