Product Structure

Working Principle

Discover the cutting-edge technology behind our permanent magnet frequency conversion air compressor. Utilizing a sophisticated pressure sensor, it precisely monitors real-time system pressure and air consumption. Seamlessly, it adjusts the motor speed with the precision of an electric and frequency converter while maintaining constant torque. This innovation ensures optimal regulation of system pressure, allowing compressed air to be delivered exactly as required. Experience dynamic adaptability: when air demand drops, the compressor intelligently reduces rotational speed to diminish compressed air output, and conversely, amplifies motor speed to boost air supply, guaranteeing unwavering system pressure stability.

Leveraging the brilliance of vector control technology, our unit operates across an expansive speed spectrum, minimizing motor temperature rise to provide the ideal torque for smooth air compressor operation. The system expertly balances the motor's current, discerning between torque-generating components and auxiliary current aspects. This advanced technique compensates for voltage drops at the motor's endpoint, empowering the motor to unleash peak torque potential without escalating current levels, ensuring optimal performance and reliability.
