Product Structure

Working Principle

A permanent magnet frequency conversion air compressor employs an advanced pressure sensor that instantly detects actual system pressure and air consumption. With precision control via electric and frequency converters, it adjusts motor speed while maintaining constant motor torque. This ensures system pressure regulation by delivering compressed air according to demand. When air consumption decreases, the compressor reduces rotational speed, minimizing output to avoid excess. Conversely, it increases motor speed to boost air output when consumption rises, ensuring stable system pressure.

Incorporating cutting-edge vector control technology, this unit operates efficiently across a broad speed range. It minimizes motor temperature rise while delivering ample torque for smooth compressor operation. The motor's current is expertly managed, with vector control technology balancing the current values to determine optimal torque generation. This innovative control compensates for voltage drops at the motor end, allowing for maximum torque output without increasing the current load.


Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
