Note!
The losses have a relatively high constant proportion, i. e. the torque loss is almost irre-
spective of the load torque. The reason for this is the pretension of the belt, which is re-
quired if dynamic traversing with a high precision is to be carried out.
The application model thus considers the efficiency to be entered as a constant torque.
For the calculation always an efficiency at the highest load is assumed. Because of this
definite dimensioning, no additional constant torque has to be specified.
