“…It should be noted that according to the standard for aircraft power quality, the electric machine on the aircraft should be driven by sinusoidal voltage with distortion factor less than 2% [19]. Therefore, the harmonics caused by pulse‐width modulation (PWM) driver should be filtered by proper filters [20, 21], which means the experiment in this study is performed in a sinusoidal situation. The adoption of filters will inevitably lead to several disadvantages such as weight increase and efficiency decrease.…”

“…It is found that the discharge amplitude and repetition rate of PD change with ageing time can reflect the degradation severity [25]. Therefore, the PD number, apparent charge, and average PD phase interval in each sinusoidal cycle are extracted to reflect the winding insulation degradation severity [20]. Q s = i = 1 N Q ( i ) Δ φ = 1 N 1 i = 1 N ( φ i + 1 φ i ) where Q is the apparent charge of single PD, Q s is the sum of apparent charges in one cycle, N is the number of PD in one cycle, φ is the PD occurrence phase, and △ φ is the average PD phase interval in each sinusoidal cycle.…”

Barater are with Department of Engineering Enzo Ferrari, University of Modena and Reggio Emilia, Modena 41125, Italy. (e-mail: stefano.nuzzo@unimore.it; davide.barater@unimore.it ) and windings as well as higher stresses on coil insulations, thus efficiency and reliability are compromised [9], [10]. An evident example in this regard is represented by hairpin windings, whose full penetration in the transportation market is curbed by their inherently high ohmic losses at high frequency operations, where skin and proximity effects occur.…”
