Motor Verification

Below is a quick summary of how the motor friction values were obtained from the DS-264 motor ratings at 30 and 300 cuts.

A comparison was done against Rockwell's MPM (Medium Inertia Motor) and RDD (Rotary Direct-Drive) motors to see if our chosen motor was still indeed the optimal choice. MPL (Low-Inertia Motors) were not considered due to unrealistic inertia mis-matches. Based on a variety of selection criteria it was evident that RDD motors offered more benefits.

Finally, two realistic RDD motor choices were compared, the B21529 and B21539. The B21529 took less power than its larger B21539 counterpart at 30 cuts. However, at 300 cuts the power consumption was essentially equal.

B21529 vs. B21539

The risk for choosing the B21529 is that it may be undersized for 300 cuts, while the risk for the B21539 is over-sizing the motor and not making the machine as efficient as possible. The B21529 is the recommended choice and has been for the previous phases, because it is the smallest motor we can choose without seriously under-sizing the guide roller motors.

EE Systems Presentation

The Electrical Engineers presented separately for the systems level controls concept. The presentation was intended as a good starting point for how the controls architecture would behave in terms of cycle up/start/down, machine faults, emergency scenarios, etc.
