A 50kW linear permanent magnet generator with a novel topology has been designed and built. The main significance of the generator topology is that there is no attractive force between the stator and permanent magnet translator. The magnetic force between the magnets is reacted within a self supporting structure. The lack of magnetic forces closing the airgap and the modular nature of the generator topology makes the manufacture and assembly of the generator easier than a conventional iron-cored permanent magnet linear generator. Photos of the manufacturing process are included in this paper. The modeling techniques used to design the generator are described and a summary of the design is presented.

Magnetic and Structural Analysis of a Transverse Flux Claw Pole Linear Machine Keysan, Ozan; Mueller, Markus A. (2013-01-01) This paper details the design and testing of a novel transverse flux claw pole linear machine suitable for large superconducting generators. The machine utilises a modular claw pole transducer design with a stationary field winding which eliminates the need for cryogenic couplers and electrical brushes for a superconducting machine. The results from this prototype will enable a better understanding of the electromagnetic and mechanical structures before embarking on a more costly super-conducting design. Th...
Integrated design and optimization of a direct drive axial flux permanent magnet generator for a tidal turbine Keysan, Ozan; Mueller, M. (2010-04-01) The C-GEN is a novel topology of direct drive air-core permanent magnet generator being developed at University of Edinburgh [1]. The topology has many benefits such as; absence of cogging torque, reduced mass and ease of manufacturing. A 20 kW prototype test rig and 15kW machine for a wind turbine has been manufactured and tested previously. Initial sizing studies for wind turbines indicate that the C-GEN concept will be up to 50% lighter than conventional iron cored PM direct drive generators [1]. In addi...
Axial flux permanent magnet machine with novel flat winding made of conductor sheet Çakal, Gökhan; Keysan, Ozan; Department of Electrical and Electronics Engineering (2020-10-13) This thesis proposes a novel winding topology, called flat winding, as an alternative to the conventional windings with stranded round wires for electric machines. It is made of a thin conductor sheet by industrial automation tools such as stamping press, laser, or water jet. Since these tools are widely used in the production of electric machines, the flat winding topology enjoys the advantage of the ease of manufacturing without significant modification on the production line. Superior current ratings, sh...
Magnetic Resonance - Electrical Impedance Tomography (MR-EIT) Research at METU Eyüboğlu, Behçet Murat (2006-09-01) Following development of magnetic resonance current density imaging (MRCDI), magnetic resonance - electrical impedance tomography (MR-EIT) has emerged as a promising approach to produce high resolution conductivity images. Electric current applied to a conductor results in a potential field and a magnetic flux density distribution. Using a magnetic resonance imaging (MRI) system, the magnetic flux density distribution can be reconstructed as in MRCDI. The flux density is related to the current density distr...
Design of Double Sided Linear Motor with Easy to Manufacture Hairpin Plate Winding Çakal, Gökhan; Keysan, Ozan (2019-01-01) This paper presents a double sided permanent magnet linear synchronous motor (DSPMLSM) with novel V-shaped hairpin plate windings and diagonally placed square magnets. Unlike the conventional stranded round wires, proposed winding type offers easy manufacturing and high current densities. Air cored structure eliminates problems related to cogging torque. In order to obtain fast results, analytical magnetic field model of the motor is derived using magnetic scalar potential and verified with finite element a...
