VSD screw — permanent-magnet variable speed
The motor follows your real demand instead of running flat-out. The biggest single energy saver when air demand varies between shifts.
Overview
Permanent Magnet VSD Screw Compressor
The permanent magnet variable frequency screw air compressor adopts permanent magnet synchronous motor to drive the screw rotor and adjusts the motor speed using vector control technology. This allows the compressor's air output to be adjusted according to demand, thereby achieving constant pressure air supply, energy savings, environmental protection, and high efficiency. Compared to traditional air compressors, the permanent magnet variable frequency screw air compressor has a higher power utilization rate, significantly reducing energy consumption while effectively minimizing noise, vibration, and impact on the power grid. Adekom permanent magnet variable frequency air compressor utilizes vector control technology, ensuring that the compressor can operate smoothly across a wide speed range with minimal motor temperature rise, providing the appropriate torque to drive the compressor. Vector control technology separates the stator current into two vectors: excitation and torque, which are controlled separately before being synthesized and converted into control signals for the inverter parameters, achieving effective control of the electromagnetic torque. This allows the motor to run at lower temperatures even at low speeds. This efficient conversion technology suppresses the inevitable noise and harmful harmonics typically generated by standard inverters to the lowest possible level. By using the new generation of specialized vector frequency control, DC is converted to AC, enhancing high-temperature resistance, improving conversion efficiency, saving energy, and increasing reliability.

Product Features
State-of-the-art Compressor Airend
Optimal Energy efficiency and outstanding reliability is achieved from patented design third generation non-symmetric robust rotors, superior bearings and oil seal that help the compressor airend to operate with good dynamic balance, low vibration, low rotation speed and low noise level.
High Efficiency Air Cooler System
Big capacity models adopt double cooling fan design. The first cooling fan starts up with the compressor and the second one starts up only when the operating temperature exceeds 80℃ and it stops when goes back below 70℃ in order to save energy.
Intelligent Touch Screen Control Panel
The simple-to-use automatic electric control panel continuously monitors and displays overall system performance status with pro-active service indications, alarms for malfunctions and safety shutdowns. Advanced sequence control for multi-units installation and remote control as option.
High efficiency and energy saving inverter
Internationally renowned ABB flux vector control frequency converter - delivers high starting torque at low frequencies with minimized operating current. Energy-optimized operation: Automatically enters sleep mode and completely shuts down during low air demand, eliminating energy waste from prolonged lower limit frequency operation. Reliable load-start capability: Enables direct loaded restart without tripping when pressure falls below preset limits, leveraging the superior low-frequency starting performance of vector-controlled drives. Enhanced energy efficiency: Avoids unnecessary power consumption from extended minimum frequency operation. Intelligent cycling: Equipped with auto sleep/wake-up functions for adaptive energy management. Comprehensive protection: Incorporates multiple safeguards including over-voltage/under-voltage protection, drive overheat protection, and short-circuit protection.
High Efficiency Permanent Magnet Motor
IPM motor constructed with neodymium iron boron permanent magnet materials can prevent demagnetized even under high operating temperature up to 180℃. Services life is up to 15 years! Halo-resistance enameled cable with remarkable insulation performance is applied to stator coil for long service life. One common shaft structure design, motor without bearing structure to guarantee 100% transmission efficiency. No more greasing and replacement of bearings at regular interval. High temperature protection via PTC/PT100 is available. Wide adjustable speed range and high precision which lead to wider range of air capacity modulation. Compact size motor saves compressor foot print. Double layer housing with oil circulation that reduces noise level and realizes low vibration and stable operation. Very high efficiency: IE4 and IP65 protection class as options.
