Simple motor calculator based on http://www.chiefdelphi.com/media/papers/2432 but rewritten in Go for cross platform use.

You can use the tool with mcalc-[os] [motor name] [amps|torque] [value]

So, for example, to compute the motor values for a CIM drawing 30A:

mcalc-osx CIM amps 30

torque(N*m) rpm amps    output(W)   heat(W) eff
