Due to the widespread use of special motors in various fields of the national economy, with the rapid development of the national economy and the power industry, motors (including small and medium-sized motors) will face broad development space.

With the adjustment and optimization of the product structure in small and medium-sized motors, special purpose motors will become the focus of the motor industry's development, and their market demand and development speed will be in a leading position in this industry. Large enterprises in the small and medium-sized motor industry produce a wide variety and series of motors, with superior comprehensive strength; Smaller enterprises focus on the production of specific types or types of motors, striving to gain an advantage in the segmented product market.

For a long time in our country, there have been few varieties of special products for small and medium-sized motors, and the product structure is unreasonable, manifested as more basic series and fewer derivative special series; There are many general varieties but few specialized varieties. According to market needs, various enterprises have also focused on the development of specialized motors. After technological transformation during the "Tenth Five Year Plan" and "Eleventh Five Year Plan", product structures have been adjusted, and special specialized motors have developed to varying degrees. It is expected that during the 12th Five Year Plan period, the ratio of standard series motors to special purpose motors in China will be about 4:6, while the ratio of ordinary standard series motors to special purpose motors in foreign countries will be 3:7. Therefore, some efficient and energy-saving motors, high-grade export motors, and electromechanical integrated special motors will have good market prospects.

Special motor is a fuzzy concept compared to traditional brushless DC motor and AC asynchronous motor. Traditionally, except for brushless DC motors and AC asynchronous motors, all motors are called special motors. Motors that are not used in special occasions are special motors.

According to the book "Special Motors and Control" (authored by Wang Tiecheng), equipment such as generators and transformers belong to special motors.
