Working Principle
Our permanent magnet frequency conversion air compressor employs a sophisticated pressure sensor to instantly detect the real-time system pressure and air consumption. Through precise control via an electric and frequency converter, it modulates the motor speed without altering the motor's torque, thereby stabilizing the system pressure and delivering compressed air based on actual demand. As system air consumption decreases, the compressor's output surpasses usage, prompting the inverter to reduce speed, thus cutting down compressed air production. Conversely, increased air consumption triggers higher motor speeds, ensuring a stable pressure by meeting air demand.
Featuring advanced vector control technology, our unit operates efficiently across a wide speed range while minimizing motor temperature rise. This ensures the motor delivers optimal and sufficient torque for seamless air compressor operation. Vector control technology intricately manages motor current, distributing it to balance torque generation and other current components. This cutting-edge technique compensates for voltage drops at the motor end, maximizing torque output without increased current, ensuring peak performance.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Saving
Our frequency conversion regulation significantly reduces the actual power consumption of the compressor, ensuring that energy is effectively utilized for air compression.
Cost Reducing
Leveraging permanent magnet frequency conversion technology, our compressors achieve over 35% energy cost reduction, and the lifecycle cost can drop by an average of 22%. The initial investment is typically recouped within 1 to 2 years.
Steady Pressure
