Development Trends of Micro DC Motor Industry

Mechatronics integration

With the development and application of power electronics technology, computer technology, microelectronics technology, and control theory, the application field of micro DC motors is becoming increasingly widespread. Behind the continuous improvement of automation and intelligence levels in various machinery and equipment is a large number of micro DC motors that are connected to computers, motor controllers, power converters, sensors, and other aspects under various working conditions, while also integrating with the subsequent actuators or loads. In such a work scenario, the motor is no longer a single discrete component, but a complete electromechanical integration module that can achieve predetermined functions together with the starting device, control device, and subsequent mechanism.

Permanent magnetization

Replacing the excitation coil with permanent magnet materials can reduce the volume and simplify the structure of the motor. The development of motors towards miniaturization and electronicization is inevitable, and the application of permanent magnet materials in micro DC motors is a trend.

digitization

The emergence of various new structures and principles of motors, as well as the improvement of control accuracy requirements for traditional motors, have put forward new requirements for micro DC motor control systems. The use of analog circuits to control motors is currently exiting the historical stage. The use of general-purpose computers, DSP controllers, FPGA and other programmable controllers to achieve motor control has rapidly developed. Correspondingly, the level of intelligence in modern motor control systems is rapidly improving, constantly advancing towards high-precision, high-performance, networked, information-based, and system chip based directions.
