The permanent magent synchronizing variable frequency compressor is a most recent compressor with excellent quality and high efficiency and energy saving at present. It is an advanced technique owned by only a few advanced countries and zones in the world. It is a high-end tendency for the future compressor development. The design concept and technical measure has broken through the traditioncal concept. It integrates the most sophisticated and energy saving technical factors.
PM motor has 2~ to 7% higher working efficiency than three-phase asynchronous motor. No matter in underloading or overloading conditions, PM compressors keep high working efficiency while three-phase asynchronous motor will have fluctuant efficiency according to the loading conditions. Therefore, compressors with PM motor will save 8% to 30% energy than those with three-phase asynchronous motor.Specialized PM motor has power factor large than 0.95, even close to 1 in some models. Moreover, PM compressors are installed with frequency converter to realize variable frequency starting and decrease the impact to compressor unit and power grid during starting, so as to save operation costs.
1.servo air compressor is a modern new technology air compressor with novel and beautiful appearance.
2.Internally efficient, energy saving!
3.Small machine size, Silent ,durable and run smoothly!
4.Save many troubles of regular maintenance and replacement.
How To Save Energy?
1)The efficiency of the PM motor is always maintained at the level of about 0.95, the power factor is close to 1, and it is increased by 5%-10% compared with the same specifications of the asynchronous motor . The motor is always maintained high efficiency whatever at a light or heavy loads.
2)Variable Frequency start, reducing the energy consumption of air compressor start, a substantial reduction in starting current and maximum power load, saving a lot of electricity, allowing unlimited start and stop, and does not affect the motor life.
3)The comprehensive energy saving of servo air compressor reach the rate of 20% -35%, power saving is considerable. Machine efficiency is more 12% to 18% than ordinary air compressor, and it belongs to IE3 energy efficiency standards,The increasing purchase cost is generally recovered within 1 year!
Example: Rated power 30kW screw air compressor
If 16 hours a day/5600 hours a year. Electricity payment is 0.16USD per KW/H, SF=1.2:
Normal screw compressor has three losses:
C.Motor efficiency loss
Calculation As Follows:
A. Unload loss=25% unloading time*The loss of the current load during no-load time (45%):
Unload loss=0.25*(0.45*1.2*30*5600)*0.16= 3628.8 USD/Year
B. Pressure loss=75% loading time* The loss of the pressure loss(2bar/14%)
C. Motor efficiency loss: 30kw The servo motor is about 5% higher than the normal motor:
motor efficiency loss=30*1.2*5600*0.05*0.16=1612.8USD/Year
Total cost savings: 3628.8+3386.88+1612.8=8628.48USD/Year
Total cost of normal 30kw air compressor: Cost of 75% loading time + Cost 25% unloading time
Power saving reached:8628.48/27820.8=31%
