With improvement of NdFeB permanent magnetic technology in China, properties of magnetic steel are of high magnetic flux, high temperature
resistance and uneasy demagnetization. Through dozens of years of development, our enterprise has independently researched and developed
ultra-effective rare earth servo permanent magnetic variable-frequency screw air compressor, we use 0. 35mm, N42SH high-performance silicon steel
sheet matching it to meet its characteristics of small volume and magnetic permeability, shrinking volume and weight of motor by over one time,
average center height is lower than 3-5 seat numbers of original asynchronous motor. We boldly use fully stretched aluminum design for machine body.
it' s beautiful and has high strength, which overturn domestic concept of cast iron case and reaches characteristics of small volume, large energy, high
performance and high efficiency. This technology is only mastered by a minority of countries in Europe, America and Japan and other countries, while
its power range is 7. 5kW-160kW. Such complete permanent magnetic variable-frequency air compressor of the whole series fills up domestic blank
Servo energy-saving system uses self-researched and developed patented servo actuator and highly efficient rare-earth permanent magnetic servo
motor as core control system whereby the former uses high-performance dSP hardware platform to make faster response of servo control, higher
precision and more stable rotating speed. In algorithm, the most advanced voltage space vector algorithm and current rotating speed double
closed-loop PID control algorithm are used, and rotating speed control of host machine and that of motor are combined. According to pressure
transmitted by permanent magnetic air compressor control system, flow signal and feedback signal of pressure sensor, rotating speed and torque
output can be intelligently regulated, thus making real balance between supply and demand of dynamics, effectively solving loss of high-pressure
conservation is reached, comprehensive electricity-saving ratio reaches 30%-80%, and economic benefit is quite considerable ecision and high energy
throttling and realizing perfect combination of permanent magnetic motor and actuator. The goal of high efficiency, high pre
