FAQ

Q: Yuav ua li cas radial magnetization txawv ntawm diametral magnetization nyob rau hauv lub tog raj kheej hlau nplaum?

A: Diametral magnetization tsim ib qho chaw sib nqus sib nqus sib nqus thoob plaws tag nrho txoj kab (ncej nyob rau sab nraud ntawm sab nraud). Radial magnetization yuam cov magnetic vectors taw tes rau sab nraud los yog sab hauv raws tag nrho 360-degree vojvoog, tsim lub nplhaib symmetrical qhov tseem ceeb rau sab hauv rotor tsim.
