(1) Ratio ( i = N in / N out)
(2) These values are measured by gearbox with ratio 100 (2-stage) at 3,000 rpm no loading.
(3) Backlash is measured at 2% of Nominal Output Torque T_2N
(4) Applied to the output shaft center at 100 rpm.
(5) These values are measured by gearbox with ratio 10 (1-stage) or ratio 100 (2-stage) at 3,000 rpm no loading.
By lower ratio and/or higher RPM, the noise level could be 3 to 5 dB higher.
