电动机发展4（Motor development 4） Research on product analysis and technology development of micro motor industry in China Section 1 the overall development trend of Chinas micro motor industry in the past 2012-2016 years I. Analysis of industry characteristics Our country for many years because of the importance of manufacturing technology to improve and reform, especially the introduction of advanced technology and equipment, micro motor industry has initially with the characteristics of modern mass production, mainly concentrated in the household appliance with AC single-phase motor and DC motor. Generally speaking, the micro motor of our country has the following characteristics: The micro motor is a product of various specifications and wide application field according to the motor industry, products are divided into permanent magnet DC motor, brushless DC motor, stepper motor, single phase asynchronous motor, AC series motor, synchronous motor, servo motor, ultrasonic motor, linear motor, divided by use of motor the car, motor, household appliances, motor, information processing machine driven by motor, industrial automation and control of motor with audio-visual equipment. China has a vast territory, a large population, rich raw materials, the national economy and peoples living standards improved rapidly, all kinds of micro motors have good prospects for development. Chinas micro motor industry, in addition to military micro motors and components, is open to the outside world and relatively fully entered the market economy industry. After the reform and opening up, foreign micro motor industry well-known enterprises, the full investigation of the Chinese market in the micro motor, using the natural resources of our country labor intensive and rich material resources characteristics, investment and set up factories in China, the establishment of micro motor production base, the establishment of a wholly foreign-owned enterprise micro motor.
