# 3 Phase Motor Current Calculation Formula Explained

Today I am sharing with new simple and easy **3 phase motor current calculation formula** for LT motors. In this post, I am sharing with you a nameplate of 3 phase low-voltage induction motor. In the nameplate, all data are given by the manufacturing companies.

## 3 Phase Motor Current Calculation Formula Explained

In the below image, I have shown a 3-phase motor nameplate. In the motor nameplate, the company provides the motor is 15 KW 3-phase induction motor. The Eff of the motor is 0.89 and PF is 0.85. The volts of the motor are 380V and the Amps are 30.1.

So this data is provided by the company. Now first see the image and after that, we start doing the current calculation of 3 phase motor. That is how completely calculate the current of three phase motor and how 30.1 amperes are given in the nameplate.

For 3-phase low voltage motor current calculation, we need the motor volts, Eff, PF. For three-phase motor amps calculation, the below formula is used.

**P/(√3xVxPfxEff)**or

**P/(1.732xVxPfxEff)**Both are the same.

#### Message:

*3 phase motor current calculation formula*(how to calculate 3-phase motor current) helps you. And now you will be able to calculate the load of 3 phase motor by using the above load current formula. Now if you have any questions or want to give us some suggestions about our blog then you can use the below comment section.

if possible write about formula or any calculation.

how to find suitable cable for load

please publish how to perform

short circuit analysis

give us some formulae equation on amps voltage ampere if u have more give us to me pls tks

Be attaching the Circuits with videos please for better understanding.

Excellent

Thank you sir for your effort teaching us online

Please tell me about calculation of overload setting.

excellent

if p= power, pf=power factor, v=voltage, i=current, eff=?

Pls, how can we reverse single phase motor

Efficiency, which is 0.85%

Thank u sir if u describe about the magnetic contractor overload relay and mccb breaker size calculation for dol and ster delta starter I will be happy
