Robust Design Optimization of Electrical Machines: Multi-Objective Approach

IEEE transactions on energy conversion, 2021
This article presents a new method for multi-objective robust design optimization of electrical machines and provides a detailed comparison with so far introduced techniques. First, two robust design approaches, worst-case design and design for six-sigma,

Hybrid Model for Electromagnetic Vibration Synthesis of Electrical Machines Considering Tooth Modulation and Tangential Effects

IEEE transactions on industrial electronics (1982. Print), 2021
With the development of vibration mechanism research on electrical machines, the tooth modulation effect was found recently. Besides, the tangential effect, which contains both the air-gap tangential force's effect and the influence of tangential ...

PWM-Induced Losses in Electrical Machines: An Impedance-Based Estimation Method

International Conference on Electrical Machines and Systems, 2021
The continuous development of electrical machines and power electronic converters is increasingly demanding for higher efficiency targets, especially in those application fields where a limited amount of stored energy is available (e.g., electric ...

Superconducting electrical machines [PDF]

open access: possiblePhysics Bulletin, 1971
The phenomenon whereby some substances lose all measurable electrical resistance has been known for more than half a century. Yet it is only during the last decade that superconductivity, as it is known, has emerged from the realms of pure physics to become the basis of a new technology.

Toward Additively Manufactured Electrical Machines: Opportunities and Challenges

IEEE transactions on industry applications, 2020
With the growing interest in electrification and as hybrid and pure electric powertrains are adopted in more applications, electrical machine design is facing challenges in terms of meeting very demanding performance metrics, for example, high specific ...

Miniaturisation of electrical machines [PDF]

open access: possibleCOMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2011
PurposeApproaches for a miniaturisation of electrical machines that are based on an electromagnetic principle have to overcome numerous challenges. Some of these are only a result of the rules of growth (or shrinkage), some are a result of the micro technological fabrication processes. This paper aims to give an overview of the current state of the art

Ferrite Permanent Magnets in Electrical Machines: Opportunities and Challenges of a Non-Rare-Earth Alternative

IEEE transactions on magnetics, 2020
Rare-earth permanent magnets (RE-PMs) are widely used in high-efficiency and high-torque density electrical machines. However, in recent years, the exclusive and unstable supply of rare-earth elements (REEs) is a major concern to substitute RE-based ...

INTRODUCTION TO ELECTRICAL MACHINES

2007
This chapter considers the basic working principles of the so-called classical set of machines. This set of machines represents the asynchronous (induction), synchronous , DC machines, and variable reluctance machines. The latter will be discussed in detail, in the book “Advanced Electrical Drives” by the same authors.
