Product Structure

 

Working Principle

Discover the brilliance of our permanent magnet frequency conversion air compressor, a marvel of modern engineering. This sophisticated machine is equipped with a cutting-edge pressure sensor that seamlessly detects the actual usage pressure and air consumption within your system. By employing precise electric and frequency converter control, it adeptly adjusts the motor speed without altering the torque of the compressor motor. This smart regulation ensures the system pressure is perfectly aligned with demand, providing an optimal output of compressed air. As system air consumption decreases, the compressor deftly reduces its rotational speed, minimizing compressed air output to match the system's needs. Conversely, it accelerates the motor when demand rises, guaranteeing a stable system pressure at all times.

Our state-of-the-art unit leverages vector control technology, enabling operation across a wide range of speeds while ensuring minimal motor temperature rise. This sophisticated approach ensures you get the precise torque needed to drive your air compressor effortlessly. The motor's current is a harmonious blend of torque-generating components and other vector control elements, which are skillfully distributed to optimize current values. Vector control techniques are exceptional in compensating for voltage drops at the motor's end, thus allowing the motor to deliver maximum torque without an increase in current.
