Owing to the fact that AFPM machines possess a relatively large air gap volume and quite often have multi-gaps, the general perception is that AFPM machines have better ventilation capacity than their radial field counterparts [52, 106].作者: pericardium 時(shí)間: 2025-3-25 07:02 作者: 因無茶而冷淡 時(shí)間: 2025-3-25 08:09
AFPM Machines Without Stator Cores,ated eddy current and hysteresis core losses. Because of the absence of core losses, a coreless stator AFPM machine can operate at higher efficiency than conventional machines. On the other hand, owing to the increased nonmagnetic air gap, such a machine uses more PM material than an equivalent machine with a ferromagnetic stator core.作者: 經(jīng)典 時(shí)間: 2025-3-25 14:42 作者: entail 時(shí)間: 2025-3-25 17:38 作者: lattice 時(shí)間: 2025-3-25 23:11 作者: 饑荒 時(shí)間: 2025-3-26 03:50 作者: recede 時(shí)間: 2025-3-26 06:31
