The Effect of PWM on Rotor Eddy-Current Losses in High-Speed Permanent Magnet Machines
High-speed permanent magnet machines, supplied by pulsewidth modulation (PWM) voltage source inverters, operate with distorted stator currents. Harmonics present in these stator currents deteriorateExpand
3-D Analytical Model of Helical Winding PM Machines Including Rotor Eddy Currents
Helical windings (or zigzag windings) are used in a number of applications, however, in electrical machines, mainly employed in low-power, high-speed permanent magnet (PM) brushless dc machines dueExpand
Electrical and Magnetic Model Coupling of Permanent Magnet Machines Based on the Harmonic Analysis
A widely used method for the magnetic field calculation in permanent magnet (PM) machines is the harmonic modeling (HM) method. Despite its many advantages, the application of this method is limitedExpand
Slotless PM Machines With Skewed Winding Shapes: 3-D Electromagnetic Semianalytical Model
TLDR
The specific focus of this paper is to provide the reader with the complete implementation and assumptions details of such a 3-D semianalytical approach, which allows model validations with relatively short calculation times. Expand
Toroidally-wound permanent magnet machines in high-speed applications
TLDR
The paper demonstrates the importance of having a flawless winding process in order to avoid excessive core losses and illustrates both merits and weaknesses of toroidally-wound machines that have not been addressed in literature. Expand
Analysis of rotor eddy current losses in slotless high-speed permanent magnet machines
Rotor eddy current losses are one of the main reasons of permanent magnet demagnetization in high-speed permanent magnet machines. In this paper the rotor eddy current losses of high-speed permanentExpand
Electrical and magnetic model coupling of permanent magnet machines based on harmonic analysis
This paper presents a new hybrid analytical approach for obtaining a complete solution of the coupled electro-magnetic model for permanent magnet machines. The main advantage of this approach inExpand
High-speed Slotless Permanent Magnet Machines: modelling and design frameworks
TLDR
The developed models for generic design framework are able to evaluate slotless PM machines’ topologies with a wide range of 3D slotless windings, and can be also used for future design optimization routines. Expand
Slotless PM machines with skewed winding shapes
• A submitted manuscript is the version of the article upon submission and before peer-review. There can be important differences between the submitted version and the official published version ofExpand
Design and Comparison of High-Frequency Resonant and Non-Resonant Rotating Transformers
This paper concerns the design and comparison of resonant and non-resonant high-frequency rotating transformers. The transformers are modeled and designed using coupled magnetic, electrical, andExpand
