W-1. Drive train for the winder

Design drive train for the winder with the following data:

• empty drum diameter 0.2 m
• full drum diameter 0.3 m
• linear speed at which the cable is to be reeled on the drum - 5 m/s
• force/tension on the cable 10 kN
• grid voltage 400 V
• no overloads

Design the drive system for lowest cost. Consider topologies with gearbox and direct drive.
