Dc motor is a motor that converts DC electric energy into mechanical energy. Because of its good speed control performance, it is widely used in electric drive. Dc motor according to the excitation mode is divided into permanent magnet, he excited and self-excited 3 categories, which self-excited is also divided into shunt, series and compound excitation 3.
When the DC power supply supplies power to the armature winding through the brush, the N-pole lower conductor on the armature surface can flow current in the same direction, and the conductor will be subjected to counterclockwise torque action according to the left hand rule. Part of the conductor under the S pole on the armature surface also flows through the same direction of current, and the conductor will also be subjected to counterclockwise torque according to the left hand rule. In THIS WAY, THE WHOLE ARMATURE winding, the rotor, will rotate counterclockwise, and the input DC energy will be converted into the mechanical energy output on the rotor shaft. It is composed of stator and rotor. Stator: base, main magnetic pole, commutator pole, brush device, etc. Rotor (armature) : armature core, armature winding, commutator, shaft and fan, etc.
