Motor Circuit Calculator
Calculate motor circuit parameters with our comprehensive calculator. Estimate current, power, torque, efficiency, and other electrical parameters for AC/DC motors.
Step 1: Motor Parameters
Understanding Motor Parameters
Motor efficiency represents how effectively the motor converts electrical power to mechanical power. Power factor indicates the phase difference between voltage and current in AC circuits.
Step 2: Circuit Configuration
Circuit Considerations
For three-phase systems, power calculation includes √3 factor. Star connection provides neutral point while delta offers higher torque. Select based on your motor specifications.

Motor Current Formula
Three Phase: I = P × 1000 / (√3 × V × η × PF)
For three-phase AC motors: Current (A) = Power (kW) × 1000 / (√3 × Voltage (V) × Efficiency × Power Factor). For single-phase: I = P × 1000 / (V × η × PF). DC motors: I = P × 1000 / (V × η).
