Product Structure

Working Principle

Experience the brilliance of innovation with our state-of-the-art permanent magnet frequency conversion air compressor. This marvel of engineering utilizes a highly sensitive pressure sensor to seamlessly gauge the actual use pressure and air consumption within the system. Through its exquisite electrical and frequency converter control, it masterfully adjusts the motor speed, while preserving the air compressor motor's torque, to finely tune the system pressure and deliver compressed air precisely as needed. When system air consumption wanes, and the compressor's output surpasses requirements, the smart inverter air compressor gracefully lowers the rotation speed, curtailing compressed air output. Conversely, when demand rises, it energetically amplifies motor speed to boost air delivery, ensuring unwavering system pressure stability.

Embrace the prowess of vector control technology that enables versatile operational speeds while minimizing motor temperature rise, ensuring ample torque for seamless compressor operation. This technology astutely orchestrates motor current, balancing the torque-generating component with other motor current elements. Vector control techniques adeptly counteract voltage drops at the motor end, guaranteeing maximum torque output without hiking the current, thereby enhancing efficiency and performance.
