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 ...
Hysteresis Losses in Sintered NdFeB Permanent Magnets in Rotating Electrical Machines
(2015)
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. ...
Toward including the effect of manufacturing processes in the pre-estimated losses of the switched reluctance motor
(Elsevier, 2015)
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 Analysis of a Self-Holding Three-Position Electric Tubular Actuator
(IEEE, 2020-08-07)
A self-holding three-position electric tubular actuator (SHTPETA) is described in the paper. The proposed linear actuator can be applied in a clutch system, where it is necessary to change certain mover positions over time. ...
Permanent magnet synchronous generator design solution for large directdrive wind turbines: Thermal behavior of the LC DD-PMSG
(2014)
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 ...
Evaluation of the Efficiency of Line-Start Permanent-Magnet Machines as a Function of the Operating Temperature
(IEEE, 2014)
The standard squirrel-cage induction machine has nearly reached its maximum efficiency. In order to further increase the energy efficiency of electrical machines, the use of permanent magnets in combination with the robust ...
Heat-transfer improvements in an axial-flux permanent-magnet synchronous machine
(Pergamon Press, 2014)
Axial-flux machines tend to have cooling difficulties since it is difficult to arrange continuous heat path between the stator stack and the frame. One important reason for this is that no shrink fitting of the stator is ...
Design and verification of a hermetic high-speed turbogenerator concept for biomass and waste heat recovery applications
(Elsevier, 2020-09-11)
Many waste heat recovery and biomass applications offer opportunities for small-scale steam turbines to produce electricity and to improve systems’ energy efficiency. However, the currently used axial turbine-based technology ...
Comparison of Commercial and Open-Source FEM Software: A Case Study
(IEEE, 2020-08-11)
5 kW high-efficiency induction motor is analyzed using 2D open-source platform and the results are compared with commercial software and measurements. The importance of equivalent circuit parameters in 2D analyses is ...
