The excitation current of shunt DC motor is in parallel with that of the rotor winding, and the excitation currents are more constant, the starting torque is proportional to the armature current, and the starting current is about 2.5 times times of the rated current. The rotational speed decreases slightly with the increase of current and torque, and the torque of overload is 1.5 times times of the rated torque. The speed change rate is small, it is 5%~15%. The speed can be adjusted by weakening the constant power of the magnetic field. The starting torque can reach the rated torque of more than 5 times times, short time overload torque can reach the rated torque of more than 4 times times, the speed change rate is large, no-load speed is very high (generally not allowed to operate under no-load).
