I agree that the term mover may not be correct. But otherwise I dont think my UUT would control the speed. If it would be controlled by the UUT then the speed would be something like 4000rpm. I think the key is that now matter the speed what my UUT wants rotate at, the "mover" (or "retarder" as...
@Brian: yes its everything made out of foam then we have a bad scenario. But you wrote yourself that if I run the drive in speed mode then the right torque will be applied automatically. So - and I am only throwing numbers here - if the drive forces 100rpm then the right torque will be applied...
@crshears: I am sorry mate, this just reflects that I am not a native speaker. Forget about "prime", lets call it simply a mover. I call it mover, because in my application it forces to move the UUT at a certain speed. And yes when I said "the engine cranks" I meant "the engine fires"... the...
@crshears: let me try clarifying the terms
UUT: unit under test in this case an automotive starter motor
Prime mover: a huge DC motor which I'd like to control in a way that it reproduces the load what the engine represents on the starter without having the engine itself.
Cranking: if you check...
Thats is the link given by youtube once I click to the share button. (it shortens the link)

Thanks!
Thanks Brian.
My assumption is that
1. if I record the speed of the flywheel on a real engine while the same starter is cranking it and then force the flywheel of my "simulator bench" to follow that speed profile, then the torque experienced by the UUT will be the same as what it would...
Hello Community,
I need to build something like this: http://youtu.be/zbXRRQmf0jI
The bottomline is that I'd like my prime mover (the big electrical motor I will control) to force the unit under test to follow a certain speed profile and by this simulating the stress it receives on a real...
Folks,
first excuse me if I ask something stupid, as an excuse I would say I am rather a software guy.
So I have a stand which has a 1000A and a 50A current transducer (will refer to them as CT. Both of them are hall effect sensors). I need to measure currents up to 900A but I also need to...
