Rated current of the three-phase ac motor is calculated

Rated current In = Pn/(1.732 * cos phi n * Un acmotortrading.blogspot.com eta).Type of Pn for the nominal power rating,the Un as the rated voltage,cos phi n as the rated power factor,eta rated electric motors 12 volt operating efficiency.Note that the power refers to the output shaft power,Pn/eta is the electrical power input.3 power rating =),rated voltage,rated current,efficiency,5kw permanent magnet generator power factor,the apparent power = rated voltage,rated current,apparent power is equal to mini electric motor the vector and active power and reactive power,power rating is refers to the mechanical output at rated power.
