It is important to understand that the armature draws just enough current that is required to develop torque to meet the load torque at the steady running speed. A 100-hp rated motor does not always deliver full 100 hp regardless of the shaft load. The motor delivers what is needed to drive the load and draws power from the source equal to what it delivers to the load plus the internal losses. Thus, the power drawn from the source may be less or more than the rated load depending on the mechanical load on the shaft. However, if continuously overloaded without added cooling, the motor would heat up and burn.
