Product Structure

Working Principle

The permanent magnet frequency conversion air compressor is designed with precision and innovation. It employs a pressure sensor to accurately detect real-time pressure and air consumption within the system. By utilizing a precise electric and frequency converter control, it dynamically adjusts the motor speed while maintaining the air compressor motor's torque constant. This enables seamless regulation of system pressure, ensuring the output of compressed air is perfectly aligned with demand. When air consumption decreases, the compressor provides more air than needed. The inverter then reduces rotational speed, decreasing output accordingly. Conversely, if more air is required, it increases motor speed to meet demand, thereby maintaining stable system pressure.

Incorporating advanced vector control technology, this unit offers versatility with a wide operational speed range, ensuring minimal motor temperature rise while delivering the adequate torque necessary for smooth air compressor function. The motor current is composed of a torque-generating component, with vector control technology assigning current values to optimize torque generation without increasing overall current. It expertly compensates for voltage drops at the motor's end, allowing for maximum torque output without additional power consumption.


Advantages of Permanent Magnet Variable Frequency Screw Air Compressor

High Efficiency and Energy Saving
The frequency conversion regulation expertly reduces power consumption in direct proportion to demand, ensuring that the energy is effectively harnessed for air compression. This leads to significant energy savings and optimized performance.

Cost Reducing
With more than a 35% reduction in energy costs, the permanent magnet frequency conversion technology drastically cuts the life cycle costs of compressors by an average of 22%. The initial investment can be recouped within 1 to 2 years, making it a cost-effective choice.

Steady Pressure
Using the PID (proportional, differential, integral) control method, this exclusive compressor offers precise adjustments to maintain unwavering system pressure stability. This leads to consistent performance and reliability.

Life Extension
The frequency conversion start significantly reduces the mechanical and power grid impact, thereby extending the service life of the machinery. This contributes to long-term durability and reliability.

Top Quality
By employing top-quality imported bearings and the latest rotor profile developments, including a large rotor with large displacement at low speed, this product ensures low noise levels and improved efficiency. This guarantees superior production quality and performance.
