Advantage for fixed speed type: Self-learning function,intelligent start/stop Detect the ambient temperature to prevent the ambient temperature from being too high temperature to cause high temperature failure. Detect tge terminal pressure of the post-treatment equipment to effectively prevent the compressed air pressure different from being too high to waste electric energy Detect the motor’s temperature to protect it. Constant pressure control:high precision constant pressure control with a pressure fluctuation range within 0.01mpa. Variable frequency soft start: remove peak current during starting,avoid the power grid impact,prevent the current impact through gradual speed regulation and improve flexibility. No idling:prevent idling of the compressor during running and reduce invalid energy consumption.the permanent magnet motor adopts a high efficiency rare earth magnet,without loss of excitation at 180,providing a long service life and saving about 6%-7% .more energy than an ordinary variable frequency motor,obtain the maximum efficiency within a wider range to make the air compressor more energy efficient High performance vector control:low-frequency starting provides a large torque and a low running current,ensuring to get a reasonable torque to drive the air compressor to run stably with the minimum temperature rise of the motor with a wide speed range.
