Baldor Star Product: PM Series
22%~34% more energy saving than normal fixed speed compressors, and 10%~15% more energy saving than normal VSD compressors.
1. Big Air DisplacementContinuous optimized double screw rotors' profile and internal structure in the airend, Advanced level of specific power and air displacement.2. Micro-computer Synchronous Control SystemThe advanced micro-computer synchronous control system realized intelligent control of the motor frequency according to the real time air consumption. The system reliability is greatly enhanced due to soft load start, elimination of current fluctuation and longer operating life time of spare parts. 3. High Efficiency PM Synchronous MotorThe motor rotor is rotated by the magnetic force from the magnetic field generated by the AC Voltage related to the stator coil. Energy saving and reliable1. The high efficiency synchronous PM motor is more energy saving than the normal variable frequency Asyn. motor.2. The PM motor can still keep a high motor efficiency even in a slow r.p.m.3. Quick response of the PM Syn. motor to the air consumption fluctuation.4. Soft start mode. The motor current would not be over the full loading current while operation and greatly reduced the impact to the power equipments. 4. Variable Frequency Control of the Cooling Fan (Optional)The variable frequency control of the cooling fan saves about 50% energy. The fan motor rotating speed would be adjusted according to the air discharged temperature, thus to reduce the energy consumption. Meanwhile, the system is more reliable because of a stable system temperature. The noise is also lower because of variable speed fan motor. 5. Eliminate Power wasteThe pressure sensor detected the pressure in the air outlet port, and send signal to the PLC. The PLC controls the output frequency of the inverter according to the pressure from the pressure sensor. And it decreases the frequency when he pressure is higher and increases the frequency when the pressure is lower, so that the pressure is always stable. The compressor controls the rotating speed of the PM Syn. motor with the inverter. In this way, a closed variable frequency control system is confirmed and realizes a stable air supply. More air output while more air consumption, less output while less consumption, and stop while no consumption. Then soft start again if there is air consumption again. The useless energy waste is totally eliminated.
