The windingloss model of central-tapped transformer in SMPS is different from that of the non-tapped transformer because the two secondary windings work in different time intervals.
中间抽头变压器由于两个副边线圈是分时工作，其线圈损耗模型不同于无抽头原副边线圈同时工作的变压器。

Active parts of slotless motor winding directly cut off air - gap field, it could produced eddy-current loss.
无槽电机绕组的有效部分直接切割气隙磁场，在其中引起涡流损耗。
