Cooperative control of an active magnetic bearing and sensorless drive system
(North-West University (South Africa). Potchefstroom Campus, 2019)
This thesis presents the cooperative control of an active magnetic bearing (AMB) and sensorless drive system. Traditionally, these two systems are considered as independent modular components within a larger system. The ...
Condition monitoring of active magnetic bearing systems
(North-West University, 2007)
In this thesis, the author contextualises condition monitoring of active magnetic bearing (AMB) systems and proposes the real-time condition monitoring of AMB systems. Three real-time fault detection, diagnosis, correction ...
An improved model for self-sensing heteropolar active magnetic bearings
(North-West University, 2007)
Active magnetic bearings (AMBs) use position feedback to actively control the forces generated by electromagnetic transducers, in order to realise stable suspension of a levitated object. The AMB concept is not new and ...
A communication sub–system for an active magnetic bearing and drive electronic system
(North-West University, 2009)
The McTronX research group has conducted extensive research concerning Active Magnetic Bearings (AMBs). This research involved the establishment of an advanced AMB laboratory to aid in assisting industries that implement ...
The development of an axial active magnetic bearing
(North-West University, 2004)
In this dissertation, the author presents the operation and development of active magnetic bearings (AMBs) , with specific focus on axial AMBs . The project objective is the development of an axial AMB system. The ...
Mechanical design and manufacturing of a high speed induction machine rotor
(North-West University, 2010)
The McTronX research group at the North–West University designs and develops Active Magnetic Bearings (AMBs). The group’s focus shifted to the design and development of AMB supported drive systems. This includes the ...
Self-sensing algorithms for active magnetic bearings
(North-West University, 2008)
Active magnetic bearings (AMBs) have become a key technology in industrial applications with a continued drive for cost reduction and an increase in reliability. AMBs require position feedback to suspend the rotor. ...
A low cost eddy current displacement sensor for active magnetic bearings
(North-West University, 2008)
The McTronX research group of the North-West University is involved in active magnetic bearing (AMB) research. An AMB is a mechatronic system that levitates a rotating axis with electromagnetic forces. The group has ...
An integrated controller for an active magnetic bearing system
(North-West University, 2007)
An active magnetic bearing (AMB) involves the suspension of a rotor by means of electromagnetic actuators. An AMB system comprises actuators, position sensors, a controller and power amplifiers. Conventional position sensors ...
Single board computer based control of an active magnetic bearing
(North-West University, 2008)
The McTronX Research group at the North-West University is currently conducting research in the use of active magnetic bearings (AMBs) for a flywheel energy storage system (FESS). Together with this, the aim of this project ...
