Introduction: Luogang brand permanent magnet variable frequency screw air compressor uses a permanent magnet variable frequency synchronous motor. Combined with intelligent frequency conversion technology, the permanent magnet variable frequency air compressor is more energy-saving than ordinary power frequency air compressors.

The servo permanent magnet variable frequency synchronous motor has a high rated working efficiency, which is 15-30% higher on average than a three-phase asynchronous motor with the same power and IE2 energy efficiency level.

Servo permanent magnet variable frequency synchronous motor. The motor stator adopts high magnetic permeability and low loss silicon steel sheets and special high-frequency windings. The rotor adopts high-performance neodymium iron boron magnets. The motor structure has small size, low inertia, high rigidity, high efficiency and low cost. Noise, fast response, smooth operation, precise control, strong overload capability and other advantages.

Features of servo permanent magnet variable frequency synchronous motor:

1. High power factor and high efficiency. The power factor of the motor is as high as above 0.95, and some are close to 1. It can save considerable electric energy in continuous fixed operating loads. The power saving effect is particularly significant in continuous periodic loads, saving about 30% of power than traditional motors. It can achieve the purpose of energy saving and emission reduction, and create benefits for enterprises.

2. Simple structure and reliable operation . Due to the inherent characteristics of permanent magnet materials, it no longer requires external energy to establish a strong permanent magnetic field in the space around it. This can simplify the motor structure, improve efficiency, save energy, and is a good energy-saving motor.

3. Unique design and durability. It generates very little heat and adopts a fully enclosed design, which perfectly solves the problem of iron-containing dust entering the motor and causing motor coil failure. At the same time, the heat resistance of the motor material is up to 180°C. Permanent magnet variable frequency screw air compressor

Product features:
1. More energy-saving than ordinary variable frequency screw air compressors.
2. Adopting the internationally advanced host machine and the best profile design, it has large exhaust volume, low noise and high stability.
3. Permanent magnet synchronous motor eliminates unloading loss, IP54 protection level, safer, more efficient and more energy-saving.
