Dynamic Response Analysis of the Rotor Using the Jeffcott Method and Performance Improvement Using Active Magnetic Bearing [PDF]
Engineering and Technology Journal, 2023 The most common component of mechanical systems today is rotating machines. In these systems, vibration is caused by rotating components. As a result, to decrease the amplitude of vibrations created by rotating equipment, it’s required to understand the ...

Magnetic Bearing Proposal Design for a General Unbalanced Rotor System enhanced because of using sensors/actuators based in nanostructures [PDF]
E3S Web of Conferences, 2019 Rotor systems need bearings in order to keep uniformity of rotational movement transmission. However, bearingsgenerate friction and energy losses due to heating transmisssion through the friction; for this reason, mechanicak bearings are replaced by ...

Design and Unbiased Control of Nine-Pole Radial Magnetic Bearing
Actuators, 2023 Typical radial active magnetic bearings are structurally symmetric. For example, an eight-pole bearing uses two opposing pairs to control one axis by winding the pair in series.
