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 ...
Mitigating noncirculating bearing currents by a correct stator magnetic circuit and winding design
(IEEE, 2020-04-06)
Different mechanisms by which bearing currents flow inside the electrical machine are well studied. In contrast, investigation and development of different techniques to mitigate these currents remain a field for improvement, ...
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. ...
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 ...
