Products details:

Hengchaowin permanent magnet variable frequency screw air compressor(PM VSD SCRW TYPE AIR COMPRESSOR) is a combination of permanent magnet rare earth synchronous motor (PM motor) and high-efficiency inverter to achieve 20-30% energy saving than ordinary screw air compressors

The permanent magnet motor uses high-performance neodymium iron boron permanent magnets, no loss of magnetism at 200 ℃, and a service life of up to 15 years.

In addition, the screw air end and the PM motor share the same main shaft. The motor has no bearings. The rotor with permanent magnets is directly mounted on the extended shaft of the male rotor, and the transmission efficiency is 100%. This structure eliminates the fault points of the traditional motor bearing and realizes the maintenance-free motor.

The power from 7.5kw(10hp) to 315kw(355hp)
