Rotary Screw Compressor:
A screw compressor is a type of rotary compressor which compresses air due to screw action. The main advantage of using this compressor is that it can supply compresses air continuously with minimum fluctuation in delivery pressure. It is usually applied for low pressure applications from 6bar to 13bars.
Working:
The basic principle of a screw compressor is as the male and female rotors are rotating in opposite direction they draw air in between them. As the air progresses along the rotors the air is compressed as the volume space between the rotors decreases, hence creating compressed air that is displace to the outlet.

Benefits of Permanent Magnetic Motor
The benefits of PERMANENTMAGNET field-excited motors over electromagnetically-excited motors include:
• Higher efficiency since no electrical energy is used or losses incurred for developing or maintaining the motor’s magnetic field
• Higher torque and power density
• Linear torque speed characteristics that more predictable
• Better dynamic performance due to higher magnetic flux density in air gap
• Simplified construction and essentially maintenance free
• More compact size
• Less bearing current due to large air gap
• Low temperature due to less rotor losses
• Ramp up time-shorter, constant power up to maximum speed
