How to Get the Most Realistic Efficiency Calculation for Gearboxes. J. Langhart. Introduction. In recent years the estimation of gearbox power loss is attracting more interest — especially in the wind turbine and automotive gearbox industry — but also in industrial gearboxes where heat dissipation is a consideration as well.
The thermal efficiency, ηth, represents the fraction of heat, QH, that is converted to work. It is a dimensionless performance measure of a heat engine that uses thermal energy, such as a steam turbine, an internal combustion engine, or a refrigerator. For a refrigeration or heat pumps, thermal efficiency indicates the extent to which the ...
If a pump is operating at 86% hydraulic efficiency and the motor is operating at 95% efficiency, the OPE will be .86 x .95 or .81% before we add in our losses. Losses typically will be 5-6 % in a properly designed system and even more in a poorly designed system.

Most electric motors are designed to run at 50% to of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor 's efficiency tends to decrease dramatically below about 50% load.
efficiency of the motor is the mechanical power output divided by the electrical power input. Once again, a sample table for motor 1624E009S is shown in Table 1. and a sample curve in Graph 1. Maximum efficiency occurs at about 10% of the motor stall torque. Table 1.
