Ac motor 110KW how much current
Consider the line current, according to the formula of three phases power: P = 1.732 * 380 * I * 0.75 According to the 110 kw to calculate: 110kW = 1.732 * 380 * I * 0.75 I = 110kW/(1.732 * 380 * 0.75) = 110 kw / 493.62 = 223 A The starting current of the motor is greater than the rated working current, which is four to seven times the rated current
But it's very short, so it's usually 1.3 to 1.7 times, and that's 1.5 times. You also have to think about the coefficient of use, and you take one of the motors. 223 * 1.5 * 0.9 = 301 A
If 380V motors, the rated current is 220A and a kilowatt is about 2 amperes. For other voltage grade, if you use power divided by the voltage (KV), the divided by the square root of 3, divided by the motor power factor, is the rated current of the motor. You look at
