Active Magnetic Bearings (amb)
A magnetic bearing is a bearing which supports a load using magnetic levitation. Magnetic bearings support moving machinery without physical contact, for example, they can levitate a rotating shaft and permit relative motion without friction or wear. In active magnetic bearings (AMB) a stable equilibrium is achieved by means of one or more control loops. The use of control loop for maintaining ...
متن کامل“Null-E” Magnetic Bearings
Using electromagnetic forces to suspend rotating objects (rotors) without mechanical contact is often an appealing technical solution. However, in real life magnetic suspensions have to satisfy many engineering performance requirements beyond the simple compensation for the rotor weight. These typically include adequate load capacity and stiffness, low rotational loss, low price, high reliabili...
متن کاملActuators for Active Magnetic Bearings
The literature of active magnetic bearing (AMB) technology dates back to at least 1937 when the earliest work that clearly describes an active magnetic bearing system was published by Jesse Beams [1]. Progress on the technology was modest until the late 1970s, when commercial development began to emerge as, for instance, described by Haberman and Liard in 1977 [2]. The state of the art in 1988 ...
متن کاملModeling and control of rotating shaft with magnetic bearings
The paper presents control system for positioning of rotating shaft ends with magnetic bearings. Problem of identification and modelling is presented as well as control algorithms. The main difficulty of the control are disturbances caused by rotation (controlled by push-pull drivers) of the shaft. Weighted minimumvariance controller has been applied and compared with built-in PD controllers. T...
