dc.description.abstractApplications for the proposed linear machine include vertical ropeless elevators, maglev trains, conveyor belts, elevator doors, pick-and-place applications, tidal or wave power generation, refrigeration and others. Applications for the proposed rotary machine are in wind power generation, ship propulsion, hybrid vehicles, robotic arms, electro-mechanical actuators, pumps and compressors.
dc.description.abstractOver the years, industries have looked to replace hydraulics with electrical machines due to significant advantages that electrical machines offer. They are more efficient, cleaner and easy to maintain and have excellent fault-tolerant capabilities that is most desirable in safety-critical applications such as aerospace and naval.
dc.description.abstractFault-tolerant capability of electric machines has been a subject of intense scrutiny in the past few years. Several design and control approaches have been proposed to address this issue. In this work, a novel design of a flux-switching permanent magnet machine with fault-tolerant capabilities has been proposed. The design concept can be applied to both linear and rotary type machines. In the proposed design, primary of the machine contains both magnets and windings. This allows the secondary of the machine to be simply made of iron making the machine very rugged. 2D and 3D finite-element simulations have been used to analyze as well as optimize the proposed design. A magnetic-circuit based modeling technique has also been developed to analyze the machine. An experimental prototype has been built to validate the simulations. Fault-tolerant control of the proposed machine under open-circuit and short-circuit faults has also been explored in this work.
