Constant torque and constant power zone in DC motors Drive.Easy tricks for understand.

Constant torque and constant power zone in DC motor Drive.

Basically motor has adopted two speed control method,one is Below base speed and another is above base speed.

Achieving of below base speed is by variation of voltage and above base speed by variation of flux and current.

So this is a simple trick for understand to find constant power and constant torque zone in DC motor drives.
