Characteristics and Deficiencies of the Permanent Magnet Variable Frequency Air Compressor

Click here to get more information.

Features of Permanent Magnet Variable Frequency Air Compressor:

1. Stable Air Pressure

The permanent magnet variable frequency air compressor features stable air pressure due to the stepless speed regulation inherent in the frequency converter. It can quickly adjust to large gas fluctuations and offers exponentially improved air pressure stability compared to power frequency operation.

2. Starts Without Impact

The frequency converter includes a soft starter function, which means the starting current is only 1-2 times larger than the rated current, significantly less than the more than 6 times current experienced during power frequency starts. This feature reduces detrimental effects on the grid and the mechanical system.

3. Variable Flow Control

Unlike traditional compressors that work in one displacement, variable frequency compressors operate over a broader range of displacements. The frequency converter adjusts the motor speed in real-time according to actual gas consumption, allowing the air compressor to automatically sleep during low gas usage, thereby reducing energy loss.

4. Good Voltage Adaptability

Thanks to overmodulation technology, the frequency converter can output sufficient torque under slightly low AC power voltage conditions, and it prevents high voltage from being sent to the motor when the voltage is slightly high. This feature is particularly advantageous for self-generating applications and low grid voltage scenarios.

5. Low Noise

The majority of variable frequency systems operate below the rated speed, reducing mechanical noise and wear. If the fan is also driven by frequency conversion, it can significantly reduce the air compressor's operational noise.

Summarizing the Deficiencies of Permanent Magnet Variable Frequency Air Compressors:

1. Fear of Demagnetization

The permanent magnet motor used in these compressors is susceptible to demagnetization, especially when exposed to high temperatures over long periods.

2. Troublesome Maintenance

Maintenance is more complicated compared to traditional compressors. Removing the motor and utilizing specialized tools for maintenance increases the complexity and professional skill required.

Permanent Magnet Motors Benefit Compressors

Product Introduction:

Benefits of Permanent Magnet VSD Screw Air Compressor:

Permanent magnet motors offer increased energy efficiency compared to conventional asynchronous motors, providing an average efficiency increase of 5%-10%. This efficiency saves users substantial electrical costs. The motors are also compact, lightweight, and highly reliable.

The air compressor’s frequency conversion technology allows the inverter to reduce motor speed and gas production when less compressed gas is needed, thus lowering electricity costs.

In contrast, fixed-speed air compressors remain in an unloaded state, with the motor running at 100%. This not only causes greater damage to the motor from frequent startups but also wastes a significant amount of energy and generates considerable noise.

Permanent Magnet VSD screw compressors, such as JAGUAR, utilize high-performance motors, ensuring extended lifespan and superior operational performance.
