SAV-M Permanent Magnet Variable Frequency Screw Air Compressor

The permanent magnet motor is integrated with the main unit, eliminating gears and belts, resulting in superior transmission efficiency.

It features no high starting current, smooth linear operation, constant voltage control, and significant energy savings.

The fully enclosed variable frequency drive design ensures good operation even in harsh environments.

The upright design ensures that the lubricating oil on the end face of the permanent magnet motor and the helical rotor is fully wetted, further improving the cooling effect of the lubricating oil.

The oil-cooled permanent magnet motor adopts a fully enclosed structural design, which is waterproof and dustproof. It uses the internal lubricating oil of the air compressor for heat dissipation, eliminating excess oil cooling energy consumption, preventing demagnetization, ensuring a long service life, and guaranteeing reliable energy-saving performance.

The amount of lubricating oil injected into the bearings and compression chamber is precisely calculated, and the lubricating oil is sprayed in the direction of air compression, which significantly reduces unnecessary oil resistance during compression. Combined with Fusheng's consistently high-precision rotor, this results in outstanding efficiency.

The optimized independent air intake duct design reduces intake noise while increasing air density and improving intake efficiency.

It adopts a high-efficiency external rotor axial flow fan, without an independent fan motor, with low starting current, smooth operation and low noise.

The fan blades are designed with biomimicry, providing strong cooling performance and very low operating noise.

The system and structural layout both adhere to the principles of high reliability, high efficiency, and low noise.

It adopts trivalent blue-white environmentally friendly zinc connectors with end face sealing to prevent leakage.

Non-asbestos gaskets resistant to high temperature and pressure protect the health of operators.
From its design concept to the application of its various components, the SAV-M permanent magnet variable frequency series air compressor boasts higher efficiency and therefore a higher energy-saving rating. Its integrated design also reduces its footprint.

The ultra-high efficiency motor reduces equipment power consumption, meeting the requirements of low-carbon and energy-saving.

Combining Fusheng's high-efficiency chassis and rigorous system design, it brings customers an exceptional energy-saving experience.

It features high starting torque, low operating noise, low motor temperature rise, and can achieve an unlimited number of starts, resulting in more thorough energy-saving efficiency.

This design avoids the high failure rate and poor coaxiality of traditional motor bearings, thus improving the reliability of the rotation system.

Using permanent magnets, high-performance and high-power factor design, no copper/iron losses, motor efficiency exceeding IE4, providing stable operation and improved overall lifespan.

Permanent magnet synchronous motors can maintain good working condition even at low speeds and can output stably within the speed regulation range, which is far superior to traditional induction motors. They can also maintain high efficiency under light loads.

The design using permanent magnets wound with ground wire reduces the size and weight of the motor, reducing its volume by more than 35% compared to traditional induction motors, resulting in a highly lightweight design.
