LV 11368 Izgudrojuma formula 1. Vēja agregāts, kas satur uz torņa novietotu pagriežamu pamatni, uz kuras novietoti lāpstiņu vējrati, kas tieši savienoti ar divrotoru elektroģeneratoru, atšķiras ar to, ka, nolūkā paaugstināt drošību, nesamazinot īpatnējo jaudu, ģeneratora rotori ir divpakešu bez tinumiem, kas viens pret otru vērsti ar savām zobvirsmām, enkurtinums ir gredzenveida un novietots nekustīgi uz ģeneratora korpusa starp ārējā rotora paketēm, kas atdalītas no korpusa un enkurtinuma ar nefunkcionējošām gaisa spraugām, ierosmes tinums ir gredzenveida,kas novietots uz viena no sānu vairogiem uz vienas ass ar rotoru, pie tam vējrati uzstādīti ģeneratoram vienā pusē attiecīgi uz iekšējā un ārējā rotora vārpstām, pie kam lielākā diametra vējrata lāpstiņas ir novietotas aiz mazākā diametra vējrata lāpstiņām.
2. Vēja agregāts pēc 1.p., kas atšķiras ar to, ka, lai paaugstinātu tā drošumu un nodrošinātu vienmērīgu vējrata orientēšanos pa vējam, vējratu griešanās ātrums ir apgriezti proporcionāls to inerces momentiem.
3. Vēja agregāts pēc p.l.vai 2., kas atšķiras ar to, ka, nolūkā mazināt trokšņu līmeni un nepieļaut ekoloģiski kaitīgas frekvences, vējratu lāpstiņu skaits ir savstarpēji pirmskaitļi, piemēram, divas lāpstiņas mazākā diametra vējratam un trīs - lielākā diametra vējratam.
