How can I calculate the coefficient of torsional viscous ,
May 06, 2017· 1) Can I just divide friction torque by nominal speed to get the coefficient of torsional viscous damping? Which would be 127 x 10^-4 Nms/rad (the same units)? 2) I'm also wondering how torsional viscous damping from a load would be reflected back to the motor shaft through a reduction gearbox?
