“…The sources of eddy current loss of PM are revealed with air‐gap magnetic flux harmonics and inverter time harmonics [14–16]. The rotor temperature of the high‐power high‐speed PM machine has been studied by different cooling schemes [17]. The temperature rise of PMSM is analysed by the equivalent thermal network and finite‐element software collaborative simulation [18, 19].…”

Recently, the high‐performance and high‐reliability permanent‐magnet synchronous machine (PMSM) has attached intensive attention due to development of electric vehicles (EVs). In this study, in order to improve the capability of output torque, an improved method of interior PMSM (IPMSM) for EV based on winding transformation (WT) strategy is proposed. In the proposed method, the power electronics technology, the vector control algorithm, and the multiple‐field analysis including electromagnetic field, fluid field, and temperature field are combined. Therefore, the steady‐state and dynamic performances of WT‐IPMSM are analysed comprehensively. The accuracy of the temperature field calculation is improved by the electromagnetic–thermal iterative method. Meanwhile, the influence of pulse‐width modulation time harmonics caused by inverter on the eddy current loss of PMs and related laws is summarised. Finally, the effectiveness and feasibility of the proposed method is verified by the prototype test.

“…Some induction generators are also used in high-speed operation [4][5][6]. However, the induction generator has a complicated structure, a large amount of losses on the rotor and low efficiency [7]. Therefore, the permanent magnet (PM) generator has the advantages of simple structure and high efficiency, and is more suitable for high-speed operation [8].…”

In the direct drive waste heat power system, the turbine is directly connected to high-speed permanent magnet generators (HSPMGs), and the transmission efficiency, service life and system volume can be obviously improved by removing the gearbox and screw rod. However, in the design of high-speed electrical machines, a comprehensive multiphysics analysis must be conducted in order to meet various requirements of electromagnetic, mechanical and thermal specifications simultaneously. The design of one HSPMG by the multiphysics approach for the electromagnetic and loss characteristics, rotor stress, rotor dynamics and fluid-thermal parameters, which satisfies all specified multiphysics constraints, is presented. The theoretical results are confirmed by the experimental results on a prototype in terms of electromagnetic, mechanical and thermal characteristics, such as induced voltage, load current, rotor continuous operation and temperature distribution.
