Product Structure

Working Principle

Delve into the cutting-edge technology of Sanzhi's permanent magnet frequency conversion air compressor, which ingeniously integrates a pressure sensor to instantly and accurately detect the real-time pressure and air consumption demands of your system. Utilizing the sophisticated synergy of electric control and a frequency converter, this marvel smoothly adjusts motor speed while maintaining the unwavering torque of the air compressor motor. This allows for perfect regulation of system pressure, ensuring that compressed air output aligns seamlessly with actual demand. As system air consumption decreases, the inverter air compressor intuitively reduces rotational speed, maintaining efficiency by minimizing compressed air output. Conversely, it adeptly increases motor speed to boost compressed air output, thus upholding stable system pressure effortlessly.

By harnessing the transformative power of vector control technology, Sanzhi's unit exhibits unparalleled adaptability, operating across an extensive range of speeds while ensuring minimal motor temperature rise. This revolutionary approach guarantees sufficient torque to drive the air compressor with seamless precision. Within the motor current, a harmonious blend of the torque-generating component and other vector control technology components distributes current values with impeccable accuracy. Vector control techniques offer optimal compensation in response to voltage drops at the motor end. This allows the motor to deliver maximum torque without elevating current levels, showcasing a level of efficiency and performance that is truly extraordinary.
