Ratio ( i = N in / N out )
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
Backlash is measured at 2% of Nominal output torque T2N.
Applied to the ourput flange center at 100 rpm.
Max. motor weight* (kg) = (0.1 x Mb) / (motor length (m))
*with symmetrically distributed motor weight
*with horizontal and stationary mounting
