Abstract
The additive manufacturing approach is considered a new manufacturing technology method and is evolving dynamically in recent years. It is advancing and achieving as the key enabling technology in a wide range of applications, from medical sciences to the aerospace and automotive industries. This novel approach opens a new path to overcome the conventional manufacturing problems and challenges by providing more design freedom, new ranges of materials, lightweight and complex geometries. According to demands metrics such as lightweight and high power density motors. This offers clear motivation to develop the advanced thermal management method with new materials and a novel additive manufacturing (AM) approach. The paper aims to provide a comprehensive review of all the attempts in various electrical machines' thermal management methods using AM method. It considers the opportunities and challenges that designers are facing while implementing these approaches. Finally, the authors make some comments/forecasts on how the AM could improve the performance and manufacturability of the future thermal management system of electrical machines.
Highlights
The fundamental design procedure of the electrical machine has been developed over decades
As the main objective of this paper is to introduce the capability of the AM method in the advanced thermal management design of electrical machines; More information about the other subjects of additive manufacturing techniques in electrical machines can be found following literatures and references [1], [2], [6], [13]–[22]
The research studies present the different steps of growth and maturity for various thermal management approaches
Summary
The fundamental design procedure of the electrical machine has been developed over decades. The conventional manufacturing techniques of electrical machines already reach their desired level, and it seems there is less possibility to do the research and development of these techniques. The new design methods and manufacturing techniques are required to provide outstanding and profound impacts. In other words, requiring advanced modern techniques allow the electrical machine manufacturers to design the novel electrical machine with whatever complex shapes, structures, and advanced materials by implementing the modern computational electromagnetic, thermal, and material approaches. The demands for clean energy technologies for different applications, for instance, wind power, electric vehicle, and electric powertrain, are rising rapidly [1]. The demands metrics are mainly concentrated on high power density, high efficiency, and lightweight electrical machines [1]
