Working Principle
Immerse yourself in the cutting-edge engineering of our permanent magnet frequency conversion air compressor. This marvel of technology utilizes an ultra-sensitive pressure sensor to monitor system pressure and air usage with remarkable precision. Leveraging the sophistication of an electric frequency converter, it seamlessly modulates the motor speed while maintaining consistent torque, ensuring that your system pressure is always balanced. This innovation delivers compressed air precisely to meet your demands. As air consumption diminishes, the system intelligently decelerates motor speed, trimming compressed air output, thereby amplifying efficiency. On the other hand, increased air consumption triggers a smart acceleration in motor speed, preserving unwavering system pressure.
Harnessing the power of advanced vector control technology, our compressor excels across a wide range of speeds, efficiently managing motor temperature rise and delivering optimal torque for flawless operation. Vector control techniques astutely divide motor current into torque and auxiliary components, ensuring a swift response to voltage fluctuations at the motor end. This dynamic management maximizes torque output without escalating current, thereby protecting your equipment and guaranteeing peak performance.
