A local seller sells this hybrid stepper and a drive for it. In the PDF I see holding torque is 86kg-cm which makes 8.45nm but no info about running torque. I asked the seller about this and he said that the running torque is double (16nm). This is the opposite I know about steppers.

What do you think?
