Industrial Motor Power Calculator

Calculate motor power, torque, efficiency, and current. Essential for motor selection, sizing, and performance analysis in industrial applications.

Formulas

Power from Voltage and Current

P (W) = V (V) × I (A) × PF

For AC motors. For DC motors, PF = 1.

Power from Torque and RPM

P (kW) = (T (Nm) × RPM) / 9549

Or: P (W) = T (Nm) × ω (rad/s), where ω = 2π × RPM / 60

Torque from Power and RPM

T (Nm) = (P (W) × 9549) / RPM

Apparent and Reactive Power

S (VA) = P (W) / PF

Q (VAR) = √(S² - P²)
