Compressor core host

■ early history and continuous improvement every 3-5 years, pursuing:

● less leakage and higher energy efficiency

● higher stability and durability

■ Atlas Copco mainframe

● new profile and vent structure

● optimize internal clearances

■ speed regulation range design for wide range of permanent magnet

electric machinery

■ permanent magnet synchronous motor

● the group independently designs and customizes permanent magnet motors

● IP55 protection grade motor

● high grade magnetic steel: 180 ° demagnetization temperature

● motor efficiency: 96%

● power factor: 0.95

● the performance is more than 20% higher than that of asynchronous motor at low speed

● independent motor cooling

1: 1 direct drive

■ real full speed regulation under full range and full speed

■ split drive chain, more mature design and simpler maintenance

■ driven by elastic coupling

● select German brand KTR high speed coupling

● after resonance simulation experiments at different frequencies, frequency hopping is not allowed
