does not differ much. Energy savings in this part depend mainly on losses caused by friction, or on losses caused by elastic deformations of functional elements (Chval, 2014, p. 890–896). Drive part – there are various design variants. The drive is used to transform and transport of energy between AC motor a machine side. With flywheel drive it is necessary to use clutch to disengage drive and machine side.

Typical clutch of forging press is a dry frictional clutch. Usually the clutch is a push-type clutch, i.e. the clutch is initially in disengaged position. To engage the clutch a pneumatic cylinder and compressed air are used. An example of such a press clutch is in Figure 2.
