Motor current calculator tool with formula for 3-phase motor or 1-phase motor.
| Motor Current based on operating data: |
This tool helps to calculate the full load current of the AC (Alternating Current) induction motor.
Let’s first understand the important parameters required for the calculation.
Voltage (V): The phase-to-phase voltage for a 3-phase supply, or the phase-to-neutral voltage for a single-phase power supply
Phase: Whether it’s a 3-phase or single-phase voltage supply. Please select from the dropdown menu.
Motor power (P): The motor power in kw or hp.
Power factor (cosΦ): The rated power factor of the motor. Usually around 0.86. Please refer to the motor specification sheet or contact the manufacturer.
Efficiency (η): The efficiency of the motor. Usually around 93%. Please refer to the motor specification sheet or contact the manufacturer.
How to calculate the motor current for a 3-phase electric motor.
A 3-phase induction motor is very common in industrial applications. By referring following formula, you can easily calculate motor current by yourself.
How to calculate the motor current for a single-phase electric motor.
Note: The motor-rated full load current is specified on the motor nameplate and datasheet by the manufacturer. We suggest referring to the manufacturer data, However; this online motor current calculator tool can be used when only the motor power is available.
