Motor Current (I) in Amps
This motor current calculator allows you to calculate the full load current of an AC Single or Three phase electric induction motor.Kindly enter the motor power, voltage, efficiency and power factor into the calculator to calculate the full load current of an electric motor.
The following formula is used to calculate the current of a 3-phase electric motor:
For a 3-phase supply with power rating in kilowatt (kW):
I = P . 1000 / √3 . V . cos(φ) . η
For a 1-phase supply with power rating in kilowatt (kW):
I = P .1000 / V . cos(φ) . η
Please note that this calculator is provided for information purposes only and typically motor full load current is specified on the OEM data sheet and shown on the motor name plate. However, this calculator is usefulwhen no documents/name plate available for the motor and only the motor rating is available & an estimate of the current is required.
