Advantages of brushless motor speed regulation
The application of automation equipment, load speed regulation is a common topic. The traditional applications for speed adjustment with high precision occasions, usually achieved by AC servo motors. In some situations with low speed, use the stepper motor speed is also a good option.
However, with the development of Brushless DC motor, brushless motor speed control has become an alternative to the servo motor and stepper motor speed control, the main reasons are as follows:
1 brushless DC motor without encoder, only three Holzer as feedback, but with the development of FOC control technology, brushless DC motor can reach a level of less than 0.5% with load under speed variation, in speed regulation precision, servo motor has been close to the level.
2 brushless DC motor + brushless DC motor drive speed control unit, only half of the cost of the servo motor, has a natural cost advantage
3 with the development of control technology, brushless motor speed control system, the servo motor than the more control function, so that customers in the application of the technology to support more, and lower costs
Compared with the traditional 4 AC frequency control, brushless motor speed control unit has the advantages of small size, high precision, control, simulation, frequency, pulse width modulation, multi bus control, while the combination ratio range is much higher than that of AC motor and inverter, is only the scope of the current brushless speed is limited to small power, the main reason is the brushless DC motor with small power production is still dominated, several thousand more than W DC brushless motor has been regarded as very large. At least the current domestic situation.
Shenzhen Haibo electromechanical technology has accumulated many years of experience in brushless motor, brushless motor speed control in the high-end domestic leading level, the production of SD, SA series brushless motor speed controller, the performance is close to the same level of Japanese Oriental motor products, while the price is closer to the needs of domestic users, will form a strong the price advantage in the market.
