  • 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
