Advanced Working Principle
Our state-of-the-art permanent magnet frequency conversion air compressor is engineered with a highly sensitive pressure sensor that instantly detects the actual pressure and air consumption within your system. Through meticulous control via an electric frequency converter, it dynamically adjusts the motor speed without altering the torque, thus regulating the system pressure flawlessly. This ensures that compressed air is provided precisely according to demand. When air consumption decreases, the system intelligently lowers the motor speed to reduce compressed air output, maintaining exceptional efficiency. Conversely, an increase in air consumption triggers a rise in motor speed, ensuring a stable system pressure at all times. Experience the pinnacle of air compression technology with Sanzhi.
Our advanced vector control technology ensures efficient operation across a wide range of speeds, minimizing motor temperature rise and guaranteeing optimal torque for seamless performance. The motor current, divided into torque and other components, is meticulously managed by cutting-edge vector control techniques. These techniques intelligently respond to voltage drops at the motor end, maximizing torque output without increasing current, thereby protecting your equipment while ensuring peak performance and durability.
