    Conversion using the Motor Current Calculation Formula

    These formulas will help you calculate the motor current needed for both single-phase and three-phase motors based on the input parameters like power, voltage, and efficiency.

    Single-Phase Motor Current Formula:

    For a single-phase motor, the formula to calculate the current is:

    I = P(KW) × 1000V × Efficiency × Power Factor

    3-Phase Motor Current Formula:

    For a three-phase motor, the formula to calculate the current is:

    I = P(KW) × 1000√3 × V × Efficiency × Power Factor
