DC Motor , Ted and small DC motor

A DC motor is a motor that converts DC power into mechanical energy. Due to its good speed regulation performance, it is widely used. The DC motor is divided into the permanent magnet, overexcitation, and self-excitation according to the excitation mode. The self-excitation is divided into three types: shunt excitation, series excitation, and re-excitation.
