Vector SVPWM AC Air Compressor VFD Variable Frequency Drive Motor Control

KY900E Series High Power Air Compressor Dedicated Variable Frequency Drive

High Power Air Compressor Dedicated Variable Frequency Drive is a variable frequency control device designed for large industrial air compressors. It achieves high efficiency, energy saving, precise gas supply, and equipment protection by adjusting the motor speed.

FEATURES

• High power adaptation
  The power range covers 15kW to several hundred kilowatts, suitable for large air compressors such as screw and centrifugal compressors.
  Support parallel drive of multiple motors to meet the requirements of complex industrial scenarios.
• Efficient and energy-saving
  Using space vector pulse width modulation (SVPWM) or direct torque control (DTC) technology, dynamically adjust the motor speed to match the actual gas demand.
  The energy-saving effect is significant, and compared with traditional power frequency drive, it can reduce energy consumption by 30% -50%.
• Precise control
  Built in pressure closed-loop control system, with real-time feedback from pressure sensors, automatically adjusts motor speed, and maintains a constant gas supply pressure (error ≤± 0.01MPa).
  Supporting PID regulation, it can achieve fast response and stable control.
• Comprehensive protection function
  Integrate multiple protection mechanisms such as overload, overvoltage, undervoltage, overcurrent, overheating, and grounding faults to extend equipment lifespan.
  Support motor soft start/soft stop to reduce mechanical impact.

Product Advantages

• High reliability
  Using industrial grade components, it can adapt to a wide temperature working environment of -20 ℃ to 60 ℃, and its dustproof and waterproof rating can reach IP55/IP65.
  Strong anti-interference ability, compatible with above 380V wide voltage input.
• Intelligent management
  Supports industrial communication protocols such as Modbus, Profibus, EtherCAT, etc., making it easy to integrate with upper computers or PLCs.
  Provide remote monitoring and fault diagnosis functions to reduce maintenance costs.
• Modular design
  Support power module expansion and flexible configuration according to needs.

Application

• Industrial sector
  Gas supply systems for large-scale pneumatic equipment in industries such as steel, chemical, and power.
  Pneumatic tools and ventilation systems in mining, tunnel and other engineering projects.
