Motor Full Load Current (FLC) Calculator

Motor Phase Type Single Phase Three Phase

Motor Power

kW HP

Rated Voltage 230 V 400 V 415 V

Power Factor (PF)

Efficiency (%)

Calculation Results

Full Load Current (A): -

Converted Motor Power: -

Power Factor: -

Efficiency: -

Phase Type: -

Formula Used

Single Phase Motor:

I = P / (V × PF × Efficiency)

Three Phase Motor:

I = P / (√3 × V × PF × Efficiency)

Where:

P = Input power (converted to watts)

V = Voltage (V)

PF = Power Factor

Efficiency = Efficiency as decimal (e.g., 85% = 0.85)

Practical Notes

• Actual motor current may vary based on load and manufacturer data.
• Use this value for breaker and cable sizing reference.
• Always consult motor nameplate data for most accurate current ratings.
• This calculator uses standard formulas and typical values for estimation purposes only.
