High-efficiency rare earth permanent magnet synchronous motor is directly connected.and uses large rotors and low speeds to ensure high-performance operation of themachine. Adopt an efficient oil and gas separation system to ensure that the oilcontent in compressed air is below 3ppm.The cooling area of the oil cooler is increased by more than 30% to ensure normaloperation in summer and no overtemperature is achieved.Independently designed host, internal pressure ratio ensures optimal power ratioIt truly achieves 0-100% continuously variable speed, minimizing the loss of uselesswork to the greatest extent.
