Electric Motor Calculator
Calculate amps, hp and kVA for electrical motors.
The calculators below can be used to calculate electric motor amps, horsepower and 3-phase kVa.
Calculate Current (amps)
horsepower (hp)
efficiency (%)
Power Factor - PF - three phase motors (0 - 1)
volts (V)
Calculate Power (horsepower)
Amps (A)
efficiency (%)
Power Factor - PF - three phase motors (0 - 1)
volts (V)
Calculate 3 Phase Apparent Power (kVA)
horsepower (hp)
efficiency (%)
Power Factor - PF - three phase motors (0 - 1)
- RLA - "Running Load Amps" - current drawn during normal operation of electric motor.
- FLA - "Full Load Amps" - amount of current drawn when full-load torque and horsepower is reached for the motor. FLA is usually determined in laboratory tests. Note! - in the calculator above FLA is RLA + 25%.
- 1 hp = 0.745 kW
