Permanent magnet synchronous motor servo control features
The motor drive is generally divided into a rotary table servo drive and a linear servo drive, and the intermediate transfer error can be eliminated as much as possible, thereby achieving high-precision operation and operation. In the control part of the permanent magnet motor servo system, it is generally divided into 10 units: the rectified power supply is the power base of the motor operation, and inside it, there are current sensor, encoder, position regulator, speed regulator, current regulator, space. Vector adjustment system and coordinate conversion adjustment system. In the preset link, the program controls the current strength and the path, and the mechanical language is transmitted by the encoder to be transmitted to the motion vector regulator (displacement controller and speed controller). At this time, the current data changes, the current The regulator begins to function, transforming the mechanical language into an external space language to “monitor” and feedback the mechanical operation to achieve the entire mechanical path.
According to the analysis of market monitoring statistics, it can be found that international servo products will be updated every five years or so, and new software algorithms are also developing with each passing day, which has brought about a new trend in the development of permanent magnet motors.
1. Integration and integration
The vertical integration of permanent magnet motor and servo system has become one of the development trends of current low-power servo systems. This kind of motor that combines drive and communication is also called intelligent motor, which closely links drive and control, and integrates motor design, manufacturing and operation and maintenance. However, the combination of permanent magnet synchronous motor and servo system is difficult, and there are many technical challenges. Therefore, in actual operation, it is difficult to occupy a mainstream position in the market.
2. Increased generalization
The environment for modern engineering construction and processing operations is diverse, and the demand for machinery is also increasing. Different motor specifications have a great impact on manufacturing costs. A large number of parameters and menu execution functions can be configured in the servo system, which makes it convenient for the user to adjust and control the vector of the motor. Different types of motors can also make their own feedback to form a semi-closed loop control system or a full closed loop control system through the servo system to expand the motor. Scope of application.
3. Improve the performance of high performance indicators
Most of the modern servo control technology has the function of parameter memory and fault self-diagnosis. It can automatically identify and adjust different types of permanent magnet motor, and return the encoder to the measuring point. The automatic tracking of the electronic gear will also input the current. Timely deployment, sampling accuracy design and data bit design per million pulses per second, improved DSP analysis speed and no cogging effect, so as to achieve miniaturization and weight reduction of the internal structure of the motor, The indicators of operation and work have been improved.
Summary: Industrialization is an important symbol of the development of modern society and a direct driving force for the future development of the country. The continuous improvement of the level of informatization has made the development of modern industry appear intelligent. As a key achievement in the high-tech industry, the feedback control technology of permanent magnet synchronous motor servo system has great potential for the development of the future machinery manufacturing industry. Therefore, we must actively explore the relevant technologies of mechatronics and realize the intelligent development of China's machinery manufacturing industry as soon as possible.
The company focuses on the production of screen motor and display screen motor.
