Permanent magnet inverter compressor is an efficient and energy-saving air compressor, which combines permanent magnet synchronous motor, inverter and air compressor intelligent inverter technology. By sensing the actual gas demand of the production line, the pressure and gas output are automatically adjusted to achieve energy saving effect. The working principle of the permanent magnet inverter compressor relies on the permanent magnet synchronous motor, which uses permanent magnets instead of excitation coils as excitation. When a three-phase alternating current of frequency f is introduced into the three-phase stator windings of a permanent magnet machine, a synchronous rotating magnetic field is generated. In the steady state, the main pole field rotates synchronously with the rotating magnetic field, so the speed of the rotor is also a synchronous speed. The main pole magnetic field formed by the permanent magnet and the stator rotating magnetic field is always relatively static and interacts to generate electromagnetic torque, drive the motor to rotate, and convert energy.
Permanent magnet inverter compressor has many advantages, such as energy saving, high efficiency, low noise, low maintenance cost and so on. Compared with traditional asynchronous motors, permanent magnet synchronous motors have the advantages of high power density, high efficiency and strong reliability. In addition, the permanent magnet inverter compressor also adopts inverter technology, which can realize smooth starting, has little impact on the power grid, and prolongs the service life of the equipment. At the same time, it can also automatically adjust according to the actual gas demand, avoiding the waste of energy.
Permanent magnet variable frequency compressors are widely used in many industries, such as iron and steel, electric power, metallurgy, shipbuilding, textile, electronics, chemical industry, petroleum, mining, light industry, machinery manufacturing, paper printing, transportation facilities, food, casting spraying, shipping terminals, military science and technology, automobile industry, aerospace, infrastructure and other fields. Especially in the need for continuous and stable gas supply occasions, such as spraying, pneumatic tools, food processing and packaging, pharmaceutical, electronics and other industries, permanent magnet inverter compressor is the preferred equipment.
