Amandla emoto P=220KW
I-motor input voltage U=380V
Ifomula yokubala amandla okunikezwa kwamandla kwezigaba ezintathu P=1.732*U*I*cosa
Amanani we-U kanye nami avumelekile

Ngokuvamile lapho injini iqala, i-cosa=0.8 isilinganiso samanje ngesigaba ngasinye IT(AV)=0.9*I
Isikhangiso esimaphakathi se-IT1(AV) sengxenye ngayinye =0.45*I

Isiqalo samanje sikhawulelwe izikhathi ezi-4 yenani elilinganiselwe
Isimiso sokukhetha ugesi wedivayisi VDRM/VRRM=(2-3)*1.414*U
