• Kwiimagnethi zeringi, iPC iqhutywa kakhulu ngumlinganiselo wobukhulu / (OD‑ID)

• I-Pc ephezulu → i-magnet isebenza phezulu kwi-B‑H curve → imveliso yokwenyani ye-flux isondele kwi-Br

• Ikhompyutha esezantsi → umngcipheko ophezulu wokuzilawula ngokwawo → ukujikeleza kombane okufikiswayo kuphantsi kakhulu kune-Br yethiyori

Oku kuchaza isizathu sokuba "ukubhitya kungasoloko kungcono". Iimagnethi zeringi ezibhityileyo kakhulu zithwala amaxabiso aphantsi eePC; nezinto ezikumgangatho ophezulu zinokuhambisa ulwelo olungalindelekanga. Xa kuyilwa iisekethe zemagnethi, iziqwenga zeepali kunye nezinye izinto zentsimbi zinokuphakamisa iPC iyonke.

I-BL Factor — I-Metric Ephambili yeeNjineli zoYilo lweeMoto

I-BL factor = i-magnetic flux density (B) × ubude be-coil conductor esebenzayo (L). Le parameter yoyilo lwe-motor olusisiseko ibeka ngokuthe ngqo i-motor torque constant.

• I-BL-factor ephezulu → amandla amakhulu okukhupha amandla anikiweyo → i-motor torque ephezulu

• BL factor = Br × Ag × N × Lg / g (Ag = indawo yesithuba somoya; N = inani leepali; Lg = ubude bekhoyili esebenzayo; g = ububanzi besithuba somoya)

• Ijiyometri yemagnethi yeringi inika i-BL factor ephezulu nge-15-22% xa ithelekiswa ne-disc equivalents ezimile okwe-flux ngenxa yokusetyenziswa kwayo okuphezulu.
