Replacing Copper with New Carbon Nanomaterials in Electrical Machine Windings
(Praise Worthy Prize, 2015)
Electrical machines have significant improvement potential. Nevertheless, the field is characterized by incremental innovations. Admittedly, steady improvement has been achieved, but no breakthrough development. Radical ...
Permanent magnet synchronous generator design solution for large directdrive wind turbines: Thermal behavior of the LC DD-PMSG
Wind is one of the most compelling forms of indirect solar energy. Available now, the conversion of wind power into electricity is and will continue to be an important element of energy self-sufficiency planning. This paper ...
Inductance Calculation of Tooth-Coil Permanent-Magnet Synchronous Machines
Analytical calculation methods for all the major components of the synchronous inductance of tooth-coil permanentmagnet synchronous machines are reevaluated in this paper. The inductance estimation is different in the ...
Hysteresis Losses in Sintered NdFeB Permanent Magnets in Rotating Electrical Machines
Permanent magnet materials are nowadays widely used in the electrical machine manufacturing industry. Eddy current loss models of permanent magnets used in electrical machines are frequently discussed in research papers. ...
The high-speed induction motor: calculating the effects of solid-rotor material on machine characteristics
(the Finnish Academy of Technology, 1991)
A method for the analysis of high-speed solid-rotor induction motors in presented. The analysis is based on a new combination of the three dimensional linear method and the transfer matrix method. Both saturation and finite ...
Design of a Traction Motor With Tooth-Coil Windings and Embedded Magnets
Traction motor design significantly differs from industrial machine design. The starting point is the load cycle instead of the steady-state rated operation point. The speed of the motor varies from zero to very high speeds. ...
Toward including the effect of manufacturing processes in the pre-estimated losses of the switched reluctance motor
The estimation of losses plays a key role in the process of building any electrical machine. How to estimate those losses while designing any machine; by obtaining the characteristic of the electrical steel from the catalogue ...
Design and Drive-Cycle Based Analysis of Direct-Driven Permanent Magnet Synchronous Machine for a Small Urban Use Electric Vehicle
A direct-driven permanent magnet synchronous machine for a small urban use electric vehicle is presented. The measured performance of the machine at the test bench as well as the performance over the modified New European ...
