Micro DC motor is the earliest invention converts electrical energy into mechanical energy equipment, disc type motor which can be traced back to Faraday's invention of the. In 1880 has become the main electrical energy into mechanical energy conversion device, but after the alternating current use has become increasingly popular, and the invention of the induction motor and synchronous motor, DC motoralso decreased importance. Until about 1960, due to the invention of SCR, magnetic materials, carbon brush, insulation material improvement, and control the speed of increasing demand, coupled with the development of industrial automation, DC motor drive system was once again the opportunity of development, to the DC servo drivesystem in 1980 has become a key technology in industrial automation and precision machining.

The characteristics of DC micro motor

1 micro DC motor has a characteristic is the motor according to the load size,automatic speed reduction, to achieve maximum starting torque. The point of AC motor is difficult. In addition, the DC motor is easier to absorb the size of the loadmutation, the rotating speed of the motor can automatically adapt to the size of the load.

The efficiency of the motor 2 micro DC motor is generally higher than other types, soto achieve the same output power, DC motor is generally relatively small. Theinstallation position is limited, micro DC motor is relatively appropriate.
