If I can remember the few things I've picked up along the way, I think
it is correct to say that with you motor exerting a force on your load
cell, and if it is not moving, then your output is 0 HP.

HP = torque x speed

Let's see...HP doesn't directly tell you about force.  You have to know
something about how it moves...Like the way electric motors can have
lots of torque at low speed, internal combustion engines are quite
the opposite...Auto manufacturers try to get the engines turning
as fast as they can to get that torque x speed figure as high
as possible...Today's cars have tiny high-revving engines and
five forward gears...now we're at the limit of my knowledge.
