We investigated the performance of designed single coil and multi-coil actuators for the Active Magnetic Bearing (AMB) system. The attractive force differs depending on the structure and actuator design. The behavior and characteristics of particular actuators differ too. Ansys Maxwell was used to perform magnetic analyses of flux, flux density, field strength, force profile and inductance profile in 2D, and magnetic flux density, field strength, current density and inductance profile in 3D. These analyses were performed for the 10 mm air gap between the actuator and rotor for single, two, three and four coils and all the parameters were compared. The quantities were compared to provide insight into the behavior of single and multi-coil actuators.
