Transmission Efficiency

This is the efficiency of connecting a gearhead to the motor to amplify the torque. It is displayed in % (percent). This is determined by the bearings used in the gearhead, the friction of the gears, and the resistance of the lubricant. Taking the case of a GN gearhead as an example, the transmission efficiency is 90 % per gearhead gear stage, and 81 % for a 2-stage gearhead, which has the fewest gear stages. As the gear ratio increases, the number of gear stages increases and decreases to 73 % and 66 %.
