Permanent Magnet Variable Frequency Air Compressor-75KW

High Efficiency of Permanent Magnet Motors

Permanent magnet synchronous motors use rare earth permanent magnet materials to manufacture their rotors. They require no excitation current, thus eliminating losses. Their efficiency is 5%-10% higher than of conventional asynchronous motors. At a power level of 74kw, a single unit can save tens of thousands of kilowatt-hours of electricity annually.

Optimized Motor and Airend Design

Permanent magnet motors offer a compact structure and stable operation. Their rotors lack windings, resulting in low heat generation and excellent insulation performance. Their failure rate is significantly lower than that of traditional asynchronous motors, making them particularly stable in industrial environments subject to long-term continuous operation.

Screw compressor airends inherently feature a simple structure and few wearing parts. When paired with a permanent mangnet variable frequency drive, they achieve a more stable operating speed, reducing impact wear on internal airend comonents and extending their service life by over 30%.
