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. ...
Unequal Teeth Widths for Torque Ripple Reduction in Permanent Magnet Synchronous Machines With Fractional-Slot Non-Overlapping Windings
(Institute of Electrical and Electronics Engineers, 2015)
Permanent magnet synchronous machines with
fractional-slot non-overlapping windings (FSPMSM), also known
as tooth-coil winding permanent magnet synchronous machines
(TCW PMSM), have been under intensive research during ...
