Product Structure

Working Principle

Experience the cutting-edge innovation in air compression technology with our permanent magnet frequency conversion air compressor. Featuring a state-of-the-art pressure sensor, this device instantly detects the real-time pressure and air consumption within the system. By employing precise control via an electric frequency converter, it dynamically adjusts motor speed without altering torque, thus regulating system pressure to deliver compressed air perfectly tailored to demand. When air consumption dips, the compressor intuitively reduces rotational speed, optimizing compressed air output. Conversely, it accelerates motor speed to boost air supply, ensuring a stable system pressure at all times.

Harnessing advanced vector control technology, this unit operates across a diverse speed spectrum while keeping motor temperature rise to a minimum, facilitating the perfect torque to seamlessly drive the air compressor. The motor current, comprising torque components and other vector-controlled elements, is strategically distributed to pinpoint the precise current values needed for optimal torque generation. By compensating for any voltage drops at the motor end, vector control ensures maximum torque output without increasing current, enhancing both efficiency and performance.
