Electrical Engineering/Motor running at high amps

Restricting the airflow to the fan will actually reduce the load on the motor. The more air the fan is moving, the more work the motor is doing.

Actually the current draw for a motor with a squirrel cage goes down as air flow is restricted.  It is counter intuitive.

I will have to disagree. CFM and BHP(Brake Horse Power) are directly related. Simply put the more air or cfm you move the higher the amp draw on your motor.
