how to calculate load torque
Full-load (Rated) Torque or Braking Torque. The Full-load Torque is the torque required to produce the rated power of an electrical motor at full-load speed. In imperial units the Full-load Torque can be expressed as. T = 5252 Php / nr (1) where. T = full-load torque (lb ft) Php = rated horsepower. nr = rated rotational speed (rev/min, rpm)
