Magneto-Thermal Analysis of an Axial-Flux Permanent-Magnet-Assisted Eddy-Current Brake at High-Temperature Working Conditions
(IEEE, 2020-05-07)
This paper proposes an analytic coupled magneto-thermal analysis of an axial-flux (AF) permanent-magnet-assisted (PMA) eddy-current brake (ECB) at high-temperature working conditions. In the topology investigated, permanent ...
Mitigation of inverter-induced noncirculating bearing currents by introducing grounded electrodes into stator slot openings
(IEEE, 2020-12-23)
Modern converter-supplied AC motors are exposed to bearing currents. Despite extensive research and development, the industry still does not have a final solution with acceptable cost and high efficiency. This paper focuses ...
Measurement Accuracy Requirements for the Efficiency Classification of Converters and Motors
(IEEE, 2019-11-28)

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 ...
Design of a Traction Motor With Tooth-Coil Windings and Embedded Magnets
(IEEE, 2014)
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. ...
