1. The airend and motor is integrated connected with each other. More compact system structure makes smaller size and smaller space to be occupied on site.
2. The system efficiency is 12%~18% higher than normal fixed speed compressor. The energy saving level is above the first class standard according to GB19153-2009.
3. More intelligent controlling system. The air capacity and system temperature could be adjusted automatically. The compressor is running in a stable temperature. The operation would be very easy.
4. Rational design to optimize the system reliability and ensure an easy maintenance.
5. A computer network remote monitoring system is used in the controller. Users can send orders to the controller according to the displayed data to realize a remote control to the compressor.
How does Baldor Permanent Magnet Inverter Screw Air Compressor save energy more than normal variable frequency screw air compressor and fixed speed screw air compressor?
1. High transmission efficiency due to integrated structure of the airend and motor. There is no coupling shaft between the airend and motor. The motor rotator directly connected with the airend bearing, there is no motor bearing, no oil seal, no belt between the airend and motor, no coupling shaft, no gears, so not any mechanical friction and transmission loss. The transmission efficiency is 100%, and no such periodical maintenances for the bearing, oil seal or coupling shaft.
2. High motor efficiency which is kept to be about 95%, and the power factor is nearly 100% which is 5%~10% higher compared with the same specification of the Asyn. motor. The motor efficiency is always high either heavy load or light load.
3. No unloading process during the operation. The Permanent Magnet Inverter screw air compressors can save the energy of unloading because the motor rotating speed is controlled by the supplied air pressure. The stable supllied air pressure makes a stable and continous loading process of the air compressor and ensure a best working status of the motor.
What other advantages does the Baldor Permanent Magnet screw air compressor has?
1. Stable air supply. The stepless speed regulation of the inverter ensures a stable air suply with the PID controller or the inverter itself. It can response quickly to large fluctuation of air consumption.
2.Reasonable the magnetic field design and density distribution. Wider motor workng frequency range and lower noise.
3. Smaller size because the motor size is only 1/3 of the normal syn. motor. So the maintenance is very easy.
4. Remote monitoring system. Customers can real-time dynamically monitor the operation of their compressors for the current, voltage, power, temperature, pressure and etc. information. And they can also receive alarm warnings SMS from the compressors to do maintenance. The parameters could also be modified by remote monitoring system.
Comparison of fixed speed screw compressors, normal variable frequency screw compressors and permanent magnet screw compressors
|Compressor Type||Fixed Speed||Normal Variable Frequency Compressors||Permanent Magent Variable Frequency Compressors|
|Connection Mode||Belt/ Direct Coupling||Belt/ Direct Coupling||Integrated Connection|
|Working Pressure||not stable, with loading/unloading process||not very stable pressure if large air consumption fluctuation||stable supplied air pressure|
|Motor Efficiency||89%~91%||85%~91%, the motor efficiency is low when the frequency is low||91%~96%, the motor efficiency could also be high even in low frequency|
|Variable Frequency Range||fixed speed||50%~100%, the variable frequency range is not wide and can not adapt to the air consumption fluctuation well||25%~100%, wide variable frequency range and can adjust to the air consumption fluctuation well|
|Noise Level||high||relatively low||low|
|Mechanical Structure||relatively complicated||relatively complicated||simple|
|Mfg. Cost||low||relatively high||high|
