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

Permitted Radial And Axial Loads

If radial force F2r is not exerted on the center of the ouput shaft X < ½ x L or X > ½ x L, the permitted radial and axial loads can be calculated by the position load factor Kb on the above diagram.

Permitted radial load F2r on center of output shaft X = ½ x L for various output speeds.
