Motor Load Calculator

Bowl Horsepower
Power Loss due to Shafting
Power Loss through Thrust Bearing
Result (Motor Load)

Motor Load :

  • Motor load refers to the current drawn by an electric motor.
  • It depends on the mechanical load connected to the motor shaft.
  • Motor load can be estimated using power, current, or motor speed.
  • Most motors operate efficiently between 50% and 100% of rated load.
  • Both AC and DC motors are commonly used in industrial applications.

Uses :

  • Used to determine the total power requirement of a motor.
  • Helps in motor selection and efficiency analysis.

Formula :

  • Motor Load = Bowl Horsepower + Power Loss due to Shafting + Power Loss through Thrust Bearing
