# Electric Motor Calculator

## Calculate amps, hp and kVA

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 Reactive 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*
