Micro motor can be divided into various categories, DC motor, AC motor, since the state angle motor, stepping motor, rotary transformer, encoder, AC and DC motor, speed generator, inductosyn, linear motor, piezoelectric motor, motor and other special motor group and other 13 categories.

Micro motor refers to the motor rated power less than 160mm in diameter or less than 750W or with special properties, special purpose. Micro motor comprehensive high-tech industry discipline of motor, power electronics, microelectronics, computer, automatic control, precision machinery, new materials, especially the application of electronic technology and new materials to promote the technological progress of micro motor.

Many varieties of micro motor (more than 5000), specifications, market applications is very broad, covering all aspects of the national economy, defense equipment, human life, those who need to see the situation of electric drive motor.

Micro motor manufacturing process, involving precision machinery, fine chemical, micro machining, magnetic materials processing, manufacturing, processing and winding insulation technology, process equipment, need a large number of high precision, in order to ensure the quality of the products also need a series of sophisticated testing equipment, is a strong industry investment.

In short, micro motor industry is a high-tech industry labor-intensive and technology intensive.
