Micro DC Motor Development History

It is the earliest device that can convert electrical energy into mechanical energy, and it can be traced back to the disc motor invented by Faraday. By 1880, it had become the main electrical to mechanical energy conversion device, but since the use of alternating current has become more popular, and the invention of the induction motor and the synchronous motor, the importance of the DC motor has also decreased. Until about 1960, due to the invention of SCR, the improvement of magnet materials, carbon brushes, insulating materials, and the increasing demand for variable speed control, coupled with the development of industrial automation, the DC motor drive system was once again developed. The opportunity, by 1980 The DC servo drive system has become the key technology in the automation industry and precision machining.
