Background

A dc motor is a motor that converts dc electric energy into mechanical energy. And the motor is widely applied to electric dragging due to the good speed regulation performance. The direct current motor is divided into 3 types of permanent magnet, separate excitation and self excitation according to an excitation mode, wherein the self excitation is divided into 3 types of shunt excitation, series excitation and compound excitation, when a direct current power supply supplies power to an armature winding through an electric brush, current in the same direction can flow through an N pole lower conductor on the surface of the armature, and the conductor is subjected to the action of a moment in the anticlockwise direction according to a left-hand rule; the lower S pole portion of the armature surface will also flow current in the same direction and the conductor will also be subjected to a counter-clockwise moment according to the left hand rule. Thus, the whole armature winding, i.e. the rotor, will rotate in a counter-clockwise direction, and the input dc power is converted into mechanical power which is output on the rotor shaft. Consists of a stator and a rotor, wherein the stator comprises: base, main pole, commutating pole, brush device, etc.; rotor (armature): armature core, armature winding, commutator, rotating shaft, fan, etc.
