Motor Full load current calculation

formula used in calculator are :

For single-phase AC motors

For single-phase motors, when kW is known:

\[ F.L.C =\frac{P_k_W \times 1000}{Voltage \times cos \phi \times \eta} \]

For single-phase motors, when HP is known:

\[ F.L.C =\frac{P_h_p \times 746}{Voltage \times cos \phi \times \eta} \]

For Three-phase AC motors

For three phase motors, when kW is known:

\[ F.L.C =\frac{P_k_W \times 1000}{\surd3 \times Voltage \times cos \phi \times \eta} \]

For three phase motors, when HP is known:

\[ F.L.C =\frac{P_h_p \times 746}{\surd3 \times Voltage \times cos \phi \times \eta} \]

Where,

  • Voltage: The phase-to-phase voltage for a 3-phase supply.
  • Rating: The power rating of the motor in kW.
  • Power factor (cosΦ): The rated power factor of the motor.
  • Efficiency (η): The efficiency of the motor.
