Companies devote themselves to the field of Brushless DC motor. Dedicated to the production of low cost brushless DC motor, brushless conventional series, no brush equipped with planetary series, no brush with a series of gears, brushless controller series and brushless non custom products series. Enterprises through ISO9001 certification, products through high and low pressure CE certification. There are four national invention patents and fifteen utility model patents. And you share the future together. For motors, we have endless passion, which is the driving force of our services, and encourage us to help customers succeed in the global scope. In the last thirty years, the research of frequency conversion speed regulation of asynchronous motor is in the final analysis, it is the method to find the torque of asynchronous motor. The rare earth permanent magnet brushless DC motor will be characterized by its wide speed regulation, small size, high efficiency and stable speed error and so on. Brushless DC motor because of the characteristics of the DC brushless motor, but also the frequency of the device, it is also known as DC inverter, the international general term. Brushless DC motor operation efficiency, low speed torque, speed accuracy, etc. are better than any control technology, so it is worth the attention of the industry.
