Isn't that what I said?! Also, I was referring to the draw (i don't know exactly how to express it). However, I think it should have been understood by the context.

I could not understand what you said.
Please do research before you post. If you don't know something, then research and ask questions rather than risk posting false information as fact.
DC motors current draw is inversely proportional to speed. When speed is zero (i.e. stall), current draw will be greatest. When speed is greatest (i.e. free speed), current draw will be least. In the case of CIM, it will draw 133 amps at stall, and 2.7 amps at free speed. It doesn't draw 67 amps per hour, nor 67 amp*hours. Take a look at motor curves. This Instructable explains it well.
