“…AM has a wide range of applications and generates complex three-dimensional shapes without any restriction. Besides, the wide range of materials used for the AM method, from metal alloys, plastic, ceramics to even bioink and biomaterial, is raising its attraction and has placed this technology among the pioneers of future manufacturing approach [2], [3]. The latest statistical reports also prove that the AM market, including all the sectors in 2018, faced an 18% growth and reached a $9.3 billion market value.…”

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 INDEX TERMS Additive manufacturing (AM), cooling systems, electrical machine, manufacturing techniques, thermal management, three-dimensional (3-D) printing, traction motors.

“…smart material utilization) [3]. AM technologies have only recently been utilised in the development of parts for electrical machines (EMs) [4][5][6], which can be attributed to the lack of AM processable materials with the necessary properties for such applications [7]. Among AM build strategies, the laser powder bed fusion (LPBF) method is the most suitable for producing highly detailed metallic parts [3] and it has been extensively applied in manufacturing structural materials.…”

“…The scientific community [9,10] alongside with a number of international bodies / agencies [11][12][13], seem to agree that future electrification roadmaps can only be achieved by relying on a number of "unconventional" technology enablers including superconductivity [14], high energy density electrochemical storage devices [15], additive manufacturing etc.. Among these, metal additive manufacturing (AM) and more specifically selective laser melting (SLM), presents undoubtedly the highest technology readiness level (TRL), when applied to EM design [16][17][18].…”

“…The application of AM to EM design is still at an early stage, although various recent works have proposed 3D printed solutions for both magnetic [17,18] and nonmagnetic EM parts [16,19]. A suitable manufacturing method for 3D printing metallic part is the so-called SLM [20], which has also recently been used for processing soft magnetic materials.…”

Among the various technology enablers for modern electrical machines, additive manufacturing plays a key role. The advantage of having a precise control of the shape of ferromagnetic structures, whilst achieving good electromagnetic performance, fits well with the design requirements of rotating electrical machines. To a certain extent, some of the physical properties of the material can be "tuned", allowing for quick trade-off studies (i.e., prototyping), as opposed to conventional manufacturing techniques. Despite being considered an enabling technology, 3D printing of soft magnetic materials for electric motors is still at an embryonic stage. This work, thus, aims in providing an initial proof of concept. For the purpose, a switched reluctance machine is chosen as a case study. Its rotor core is additively manufactured through selective laser melting. Its performances are compared to those of an identical commercial motor featuring a laminated rotor core, via in-depth experimental tests. Initial results show that the 3D printed machine can actually develop the rated power, but with an efficiency reduction.
