C-1. Design for constrained space
Design drive system for the conveyor situated in a narrow passage. L = 120 cm (see the sketch).
Fig.1. Explanation for the task.
Available information:
- One drum to be driven
- No overloads, duty cycle – 100%
- Dusty environment, abundant heat removal capability, wet floor
- Grid 400 V
- Distance between the driven drum of the conveyor and the FC (cable length) – 30 m
- Rated torque 10 kNm
- Speeds: min – 200 rpm, max - 250 rpm
- Cooling water available
Design for: (A) Design system for lowest cost. (B) Design system for highest efficiency
