Yet another Rotary canundrum: Magnetostatic engine

[ChemE]

2 microturbines should be enough to run the extractor at 1 operation per tick for all 4 stages, without switching. That's not 15 seconds per ore, but for rare ores about half a second. 2 MTs should be running your extractor about 30 times faster than you need atm.

I'm with you up until the no switching claim. Stage 1 requires 512Nm of torque so 4,194,304W at 512Nm of torque means our maximum rotational speed for stage 1 is then 8,192 rad/s.

Using the equations from: http://rotarycraft.wikia.com/wiki/Extractor

stage 1's operation time in ticks would be 900 - 60(log2(8,192) = 900 - 60(13) = 120 ticks = 6 seconds. The minimum speed required to run stage 1 at 1 operation/tick is 32,768 rad/s so we need 4x the power just to get stage 1 down to 1 op/t.

The 1op/tick speed of the stages are as follows:
Stage........Speed
1...............32,768 rad/s
2...............1,048,576 rad/s
3...............1,048,576 rad/s
4...............32,768 rad/s

Which is why it takes me 536MW to run all 4 stages at 1op/tick without switching and this is indeed the minimum required to do that.

Well with 8MW, ie: 4 microturbines, at 512Nm I get 16 rad/sec.

What I'm doing is 3-stage timing instead of the usual 2, so at stage 4 I take it down to 256Nm, so I get more speed and Stage 4 is dealt with nearly instantly.

The only stage stage that still takes an eternity compared to the other 3, is Stage 1, as with 512Nm, my speed ratios get limited.

But the other 3 are pretty much instant.

My bad again. Numbers I had gotten were minimums, not high speed.

It'll probably be a few hours before I can get ya more specifics for running it fast.

2 stages is usually the best ( 1 high torque, the other speed ). 3 or 4 stages will make their specific stages run a little faster, but running 2+ stages at the same time makes up for it.
