Working Principle
Experience the groundbreaking innovation of our permanent magnet frequency conversion air compressor system. Outfitted with cutting-edge pressure sensors, it astutely tracks real-time usage pressure and air consumption throughout the ecosystem. Through sophisticated electronic and frequency converter controls, this advanced system meticulously adjusts the motor speed while unwaveringly preserving the motor's torque. This ensures seamless regulation of system pressure, precisely matching the necessary compressed air output. In instances where air consumption decreases and the compressor's output surpasses demand, the intelligent inverter air compressor elegantly reduces its speed, thereby conserving energy by minimizing the compressed air output. Conversely, as demand crescendos, the system boosts the motor speed, augmenting the compressed air supply and guaranteeing unyielding stability in system pressure.
Unlock the potential of state-of-the-art vector control technology with our sophisticated unit. It delivers exceptional efficiency across a diverse range of speeds while simultaneously restraining motor temperature increase. This assures optimal torque, facilitating the smooth operation of the air compressor. The motor's current, a blend of torque and other values, is astutely enhanced via vector control technology. Vector control techniques adeptly resolve voltage variations at the motor's end, enabling maximum torque output without raising current levels, ensuring peak performance and steadfast reliability.
