Moment of inertia of the deflection pulleys

• Can be disregarded in most applications, though in dynamic applications it may have an im-

pact on the dimensioning.

• The moment of inertia is to be entered relative to the driving pulley and has an impact on the

dynamic torque!

• The inertial moment can be estimated by means of the inertial calculator.
