C-5. Design for long and short cables

Design drive system for the conveyor with two drums to be driven. Load sharing 50/50%. You are free to choose where the drive and the transformer (if any) will be located. Also free to choose voltage level.

Note: only one possible variant is shown on the sketch in Fig.1. Fig.1. Explanation of the task.

Available information:

• Rated torque 60 kNm (for the total conveyor)
• Operational speeds 40 - 200 rpm
• 20% overloads
• Duty cycle – 100%
• Choose between two power houses with 6000 V and 690 V voltage sources
• Power houses: constrained space (try to minimize footprint)

Design the system for lowest cost.
