Abstract:
Active
magnetic bearing (AMB) is a kind of the mechanical supporting unit, and
its working principle is based on that shafts can be suspended in the
case of the bearing depending on electrical magnetic force. When
analyzing the dynamical performances of the system, two key domains may
be considered during the first research process, these are
characteristics of AMB rotor system dynamics and the gyroscopic effect
in the system. With the second problem is dealt, and one method for
analyzing the effect in design of system is introduced, as well as its
specialty. Meanwhile, how to design the system controller is mentioned
out here and one kind of realizing scheme for that purpose presented
also. As a theoretical analysis result, two rigs of AMB system are
experimented and some answers are clear. Above can be used as a base of
design of the system.
Key words:
