Impact of Non-Uniform Flux Density on Core Losses: A Case Study on Standard Core Geometries
(IEEE, 2024)
The non-uniform flux density distribution inside magnetic cores leads to increased overall losses when compared to the commonly used uniform flux density assumption. This effect is amplified if rectangular based core shapes ...
Comparison of impedance spectroscopy and partial discharge analysis as insulation health diagnosis techniques
(IEEE, 2024)
The ageing of insulation systems in electric machines can compromise partial discharge-free designs. Regularly monitoring insulation health is crucial to prevent unexpected failures. Several authors have proposed health ...
Alternative Approach Based on Bézier Curves to Model Core Losses With the Composite iGSE Method
(IEEE, 2024)
This work addresses limitations of the composite improved generalized Steinmetz equation for core loss calculation and presents a more robust definition of the losses. First, the limitations due to extrapolation of the ...
Intuitive Degradation Mode Estimation Tool: ModEst
(IEEE, 2024)
Battery ageing is one of the main concerns in most battery applications. To reduce this degradation rate, it is key to understand how batteries age. However, the diagnosis of battery ageing is very challenging due to the ...
Experimental-Based model for Turn-to-Turn PDIV Prediction Dependent on Temperature
(IEEE, 2024)
Turn-to-turn insulation partial discharge inception voltage (PDIV) plays a crucial role in the design of the insulation system of inverter-fed motors for the automotive sector. This paper presents a turn-to-turn PDIV ...
Analysis of Multiphase Permanent Magnet Motors via Space-Harmonic Model
(IEEE, 2024)
Multiphase permanent magnet motors are gaining popularity thanks to their advantages, which include reduced torque ripple, enhanced torque capability, and fault tolerance. However, their modelling and control is more ...

Contact model for toroidal type continuously variable transmissions
(2020)
Toroidal type Continuously Variable Transmissions (T-CVT) are mechanical transmission systems where torque is transferred by means of traction forces. This transmission type holds, slip and high contact pressures that ...
Sliding performance of toroidal type CVT transmissions
(Ecole Centrale de Lyon, 2022)
Toroidal Continuously Variable Transmissions (T-CVT) are mechanisms where torque is transferred through traction forces over heavily loaded lubricated elliptical contacts [1]. Lubricated traction is governed by the shear ...
Combining experimental and FEM approaches to determine the influence of workpiece temperature on fundamental variables in the machining process
(Materials Research Forum LLC, 2024)
In machining it is common practice to use lubricants to enhance machinability, resulting in improved part quality and reduced tool wear. However, emerging efforts are centered on mitigating the environmental impact of ...
