*Amps At Load, No Load??

Greetings;

This question concerns the amperage rating for a DC motor. Is this to
say that a motor rated at 10 amps will draw this current under no load
or, is this the amperage draw when this motor is cruising under a
"normal" load or, is this the maximum the motor can sustain under load
before going ballistic?

Rated current is normally the spec for the current the motor will pass
when it is operating at rated torque and speed. Since the product of
torque and speed is power, it can also be said that the rated current
is passes when the motor is producing rated shaft power. At lighter
torque load, the motor will run faster and draw less current.
