Working Principle
A permanent magnet frequency conversion air compressor employs a sophisticated pressure sensor to instantly detect the actual pressure and air consumption within the system. Through precise electric and frequency converter controls, it adjusts the motor speed without altering the motor's torque. This regulation ensures the system pressure is optimized to meet the compressed air demand. When air consumption diminishes, the compressor's rotational speed decreases, reducing air output accordingly. Conversely, an increase in air demand prompts the motor to speed up, maintaining a stable system pressure.
Utilizing advanced vector control technology, our unit operates seamlessly across a wide range of speeds while minimizing motor temperature rise. This ensures ample torque to drive the air compressor efficiently. Vector control technology distributes motor current values to distinguish between torque-generating components and other components. It optimally compensates for voltage drops, enabling the motor to deliver maximum torque without increasing current, ensuring smooth and efficient operation.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Saving
Frequency conversion regulation significantly reduces power consumption, making energy utilization highly effective for air compression.
Cost Reducing
Permanent magnet frequency conversion technology slashes energy costs by over 35%, reducing the compressor's life cycle cost by an average of 22%. The initial extra cost can be recovered within 1 to 2 years.
Steady Pressure
Employing the PID (proportional, differential, integral) method, our compressor precisely adjusts to maintain stable system pressure.
Life Extension
Frequency conversion start reduces the impact on the power grid and machinery, significantly prolonging the service life of the compressor.
Top Quality
Featuring top-quality imported bearings and the latest rotor profile technology, our compressor boasts a large rotor, high displacement, low speed, and low noise, enhancing efficiency and production quality.
