Radial fan simulations by computational fluid dynamics and experimental validation
(IEEE, 2014)
Fans are commonly used to refrigerate electrical machines when air forced cooling is required. They are rather simple solutions that can considerably improve the thermal performance of electrical machines, so the fan ...
Methodology to Study Demagnetization Risk in Permanent Magnet Machines by Finite Element Method
(IEEE, 2017)
Nowadays the majority of applications are demanding more and more compact, cost effective and robust solutions for their electric drives. In this context permanent magnet synchronous machines are considered as a good ...
Thermal test procedure and analytical model calibration method for electrical machines
(IEEE, 2013)
In this paper a thermal test procedure and a calibration method for lumped parameter models are presented. Analytical models provide fast thermal simulations in comparison with finite element methods (FEM) and computed ...
Analytical model to calculate magnetic flux density in permanent magnet synchronous machines with static eccentricity
(IEEE, 2016)
In this article a general analytical model for the analysis of permanent magnet synchronous machines with static eccentricity is presented. The model is a continuation of [1] and it is based on Fourier time-space series ...
Experimental test bench for testing DC microgrid control strategies
(IEEE, 2017)
During the last decades the number of microgrids and their research have increased notably, as they offer a high versatility for the integration of distributed generation (DG) units and renewable energies. Among the different ...
Comprehensive analysis of voltage balancing techniques for 5L NPC converters
(IEEE, 2013)
The reduced capability of the 5L-NPC Inverter to balance the voltages of the four DC-bus capacitors makes this converter unattractive for real power applications. This is especially true if the load demands active power. ...
Emakumearen mututasun soziala: feminitatearen eta maskulinitatearen estereotipoak
(UEU, 2017)
Most of the main gender stereotypes that nowadays are still alive can already be discovered in Ancient Greece society. In this paper we will analyze Greek symbolic though using genderperspective. We want to unveil the ...
Model driven Hardware-in-the-Loop Fault analysis of railway traction systems
(IEEE, 2017)
Classical Dependability Analysis techniques, such as Failure Mode and Effects Analysis (FMEA) and Fault Tree Analysis, have been used during the last decades to demonstrate the reliability, availability, maintainability ...
Automatic detection test of current sensor faults for induction motor drives at standstill
(IEEE, 2016)
This paper proposes an automatic detection test of gain faults in current sensors. An offline test is applied when the machine is not operating. The designed test operates at standstill without being necessary to disconnect ...
Optimising Maintenance: What are the expectations for Cyber Physical Systems
(IEEE, 2016)
The need for maintenance is based on the wear of components of machinery. If this need can be defined reliably beforehand so that no unpredicted failures take place then the maintenance actions can be carried out economically ...
