Abstract: Active magnetic bearing (AMB) is as an application example
of using magnetic levitates theory in mechanical domain. Its working
principle involves contactless support of the shaft by the bearings
through electrical magnetic force. So, AMB has some good features, such
as no touch friction and wear, small motion resistance, lower power
supply and long utility time. Overseas, AMB technology has reached
mature level and increasingly products, which set up with AMB, can be
found. The ways of design and process AMB rotor system are described.
Here a number of design methods of AMB are dealt with, which mainly
include the features in the systematic design, methods of design for the
system controller, rigid shaft system and flexible shaft system.Some
numeric results are presented also.
