## Motor full load current calculator

Full Load Current is the maximum allowable current that is tolerated by the motor insulation. The input current to the machine exceeds the full load current means, the electrical machine may get damaged. Due to the excess current flow, the machine produces additional heat (Because of heat /loss =I^{2} R)., This may lead to damages to the insulation or winding of the electrical motor. Hence, Operating a machine below full load current increases the life span of the electrical motor. This Motor full load current calculator provides a full load current of the motor by selecting rated voltage and load (hp/kW)

## Formula used in Motor full load current calculator

**Single Phase AC Motor FLA (Amperes) = (P [kW] × 1000) / (V × cos ϕ)**

**Single Phase AC Motor FLA (Amperes) = (P [HP] × 746) / (V × cos ϕ × η)**

**Three Phase AC Motor FLA (Amperes) = (P [kW] × 1000) / (V × 1.732 × cos ϕ)**

**Three Phase AC Motor FLA (Amperes) = (P [HP] × 746) / (V × 1.732 × cos ϕ × η)**

*Where:*

**P [HP] , P [kW]** = Motor power rating (HP or kW),

**V** = Motor rated voltage (Volts),

**η** = Motor efficiency in decimal form,

**cos ϕ** = Motor power factor,

**1000** = Conversion factor to convert kW to W,

**746** = Conversion factor to convert HP to W.

Major thanks for the article post.Really looking forward to read more. Cool.
