introduction： There are two main control methods of DC motor：One is armature voltage control，That is, when the stator magnetic field is unchanged，The speed and output torque of the motor are controlled by controlling the voltage signal applied at both ends of the armature winding；The other is excitation field control，That is, the stator magnetic field strength can be changed by changing the excitation current，Thus control the motor speed and output torque。 When using armature voltage control mode，Because the stator magnetic field remains unchanged，Its armature current can reach the rated value，The corresponding output torque can also reach the rated value，Therefore, this method is also called constant torque speed regulation mode。
