Product Structure

 

Working Principle

A permanent magnet frequency conversion air compressor ingeniously employs a highly responsive pressure sensor that precisely detects real-time system pressure and air consumption needs. With the seamless integration of electric and frequency converter controls, the motor speed is adeptly adjusted without altering the motor's torque. This smart regulation ensures that the system pressure is maintained to deliver compressed air tailored to demand. When the system's air consumption decreases, the compressor's output exceeds the demand; the innovative inverter then artfully reduces motor speed, thereby curtailing compressed air output. Conversely, by gracefully accelerating the motor, the system can increase compressed air supply to stabilize pressure, ensuring a seamless balance in the system.

Embracing cutting-edge vector control technology, these units function effortlessly across a broad range of speeds, while ensuring minimal motor temperature rise. This brilliant synergy allows for the perfect torque needed for smooth air compressor operation. The motor current split into torque and other components by vector control ensures optimal current distribution, providing the motor with maximal torque output even during voltage drops at the motor end, all while maintaining consistent current levels. This intelligent responsiveness guarantees that the motor delivers peak performance efficiently.


Advantages of Permanent Magnet Variable Frequency Screw Air Compressor

High Efficiency and Energy Saving
With frequency conversion regulation, power consumption aligns proportionately with needs, optimizing energy usage for air compression. This ensures that every watt is smartly utilized, making the operation both efficient and eco-friendly.

Cost Reducing
With permanent magnet frequency conversion technology, energy expenses plummet by over 35%, while the compressor's life cycle costs are trimmed by an average of 22%. The initial investment pays for itself within just 1 to 2 years, making it a financially sound choice.

Steady Pressure
The PID (Proportional, Integral, Derivative) control method masterfully fine-tunes the compressor to sustain unwavering system pressure, ensuring precision and stability in operation.

Life Extension
Frequency conversion start-up diminishes the impact on the power grid and machinery, effectively extending the service life of equipment by reducing wear and tear.

Top Quality
Utilizing top-tier imported bearings and the latest rotor profile advancements, these compressors boast large rotors with significant displacement operating at low speeds. This results in reduced noise, heightened efficiency, and superior production quality.
