How do you calculate the current in a three-phase induction motor?

Question

Accepted Answer

The amount of current required for a 3-phase motor depends on its power rating and voltage supply.

The current required by a 3-phase motor can be calculated using the formula: Current (A) = Power (W) / (√3 x Voltage (V))
The power rating of the motor is usually specified by the manufacturer.
The voltage supply can vary depending on the electrical system, such as 220V, 380V, or 480V.
For example, a 10 kW 3-phase motor operating at 380V would require approximately 17.2 Amps of current.

For calculating full load current in a 3 phase system we have to use the formula W =root 3 ×VL ×IL ×cos teeta (power factor )now IL =W /1 . 732 ×VL ×P.f . Here in this formula W = power, root 3 =1.732, VL =Line voltage, IL =Line current and cos teeta= power factor.
