Total moment of inertia

[7-121] Equation 4: Total moment of inertia

Stationary torque

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

[7-122] Equation 5: Stationary torque

[7-123] Equation 6: Friction force

[7-124] Equation 7: Lifting force

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

add

is generated:

[7-125] Equation 8: Friction force

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

[7-126] Equation 9: Mass of the payload

Required torque of the application (without losses)

In order to take the efficiency of the application by the transmission of the movement via chains

into consideration, first the required torque of the application has to be determined:
