Default RPM of variable speed DC Motors

^^^^^^^^^^^^^^^^
I've never heard of anyone calculating amps per RPM, and I think that is
because it is meaningless. First question: How do you know that both
motors are developing 1 HP? Are the figures you listed measured or read off
the nameplates? Of course, you get more torque at lower speed for a given
horsepower. If the figures are accurate, then motor A is slightly more
efficient than motor B.
