Stationary torque

The stationary part of the torque consists of different individual forces:

[7-131] Equation 2: Stationary torque

[7-132] Equation 3: Friction force

[7-133] Equation 4: Lifting force

If the transported material drives against a limit stop (e. g. adjustment of the material), the force

add

is generated:

[7-134] Equation 5: Additional force

The friction of the rolls is taken into consideration by the friction force F

aux

[7-135] Equation 6: Friction force by run via rolls

The mass of the payload is calculated by the line load:

[7-136] Equation 7: Mass of the payload

Torque of the application

[7-137] Equation 8: Torque of the application
