“…Such arrangement allows to tailor heat removal required for healthy operation of the motor as a function of driving cycle/operating regime. The theoretical findings showed clear energy consumption benefits of the hybrid solution as compared with more common (liquid-cooled housing) alternative [23].…”

Thermal management of power electronics, electrical machines and drives has become one of the key enabling factors in delivering of the future high-specific-output solutions for low-/zero-emission electrified propulsion. This paper reviews heat-pipe technology in application to electrical machines with focus on opportunities and challenges associated with successful deployment of such heat transfer/removal approach. Although, the use of heat pipes in electrical machines has been explored by numerous authors over decades of research, continuous developments in the materials and manufacturing techniques have opened new design avenues, with the high-rate heat transfer, low-added-weight, high-level of integration and reliability being some of the benefits of heat-pipe enabled cooling solutions. In this paper, underpinning fundamentals of the heat pipes construction and operation are discussed, with emphasis on the new/emerging solutions allowing for a more measured integration of heat-pipe-based or assisted thermal management systems in electrical machines. A number of examples of employing heat pipes in commercial and research applications are provided from the available literature together with the authors forecasts of the possible future technology advancement.

“…The thermal conductivity of heat pipes can be up to several potencies higher compared with a geometrically similar, metallic conductor [10]. Such approaches can be found in [100][101][102][103][104][105][106][107]. In [105], a concept with 36 heat pipes in the stator of a conventional IM is analyzed.…”

Thermally induced loads in motor spindles can cause a number of undesired effects. As a result, the process capability of spindles, and thus, the productivity of a process can decrease. Future motor spindles will be exposed to higher mechanical and especially thermal loads due to trends aiming to increase power densities and maximum speeds. These trends are amplified by increasingly powerful drive concepts and developments in bearing technology. Therefore, researchers assume that it will not be possible to raise the performance potential of spindles due to insufficient cooling of its heat sources. A series of different cooling concepts have been researched and developed in recent decades. These developments have been made for different purposes. They also differ considerably in terms of their cooling principles and cooling performance. In this article, these cooling approaches and the motivations for their development are described. Firstly, the causes of heat development in motor spindles are described in a historical context. Subsequently, the effects of heat development on the manufacturing-relevant properties of motor spindles are revealed. Finally, current deficits in the area of spindle cooling and the need for the development and transfer into industrial practice of more efficient and cost-effective cooling concepts to overcome future challenges are discussed.

“…One of the aspects regarding the EV integrated chassis development that needs to be covered by the XiL environment is a thermal management system (TMS) of the powertrain. The important role of this system is emphasized by a substantial number of published research including the works [12][13][14][15], which describe the approaches used in designing TMSs for both conventional and electric vehicles. The work presented by this article, being a part of the mentioned joint project, is aimed to elaborate an experimental design of the TMS intended for the considered four-wheel-drive electric vehicle.…”

The article describes an elaboration of the X-in-the-loop (XiL) testing environment for a thermal management system (TMS) intended for the traction electric drive of an electric vehicle, which has each of its wheels driven by an in-wheel motor. The TMS features the individual thermal regulation of each electric drive using a hydraulic layout with parallel pipelines and electrohydraulic pumps embedded into them. The XiL system is intended as a tool for studying and developing the TMS design and controls. It consists of the virtual part and the physical part. The former simulates the vehicle operating in a driving cycle with the heat power dissipated by the electric drive components, which entails the change in their temperature regimes. The physical part includes the TMS itself consisting of a radiator, pipelines, and pumps. The physical part also features devices intended for simulation of the electric drive components in terms of their thermal and hydraulic behaviors, as well as devices that simulate airflow induced by the vehicle motion. Bilateral, real-time interactions are established between the two said parts combining them into a cohesive system, which models the studied electric vehicle and its components. The article gives a description of a laboratory setup, which implements the XiL environment including the mathematical models, hardware devices, as well as the control loops that establish the interaction of those components. An example of using this system in a driving cycle test shows the interaction between its parts and operation of the TMS in conditions simulated in both virtual and physical domains. The results constitute calculated and measured quantities including vehicle speed, operating parameters of the electric drives, coolant and air flow rates, and temperatures of the system components.
