WebA machine that converts the DC electrical power into mechanical power is known as DC motor. Its work depends on the basic principle that when a current carrying conductor is placed in a magnetic field, then a force exerted on it, and torque develops. The DC motor is classified into two types, i.e., the self-excited motor and separately excited. WebJun 10, 2008 · dpc (Electrical) 6 Jun 08 13:57. The saturation curve is related to the iron in the stator of the motor. If the voltage applied to the motor is increased so that the motor is operating above the "knee point" of the saturation curve, the motor will start drawing excessive current since the reactance seen at the motor terminals will decrease.
