Permanent Magnet Screw Compressor

Benefits of Permanent Magnet Motor

• Higher efficiency since no electrical energy is used or lost for developing or maintaining the motor’s magnetic field.
• Higher torque and power density.
• Linear torque speed characteristics that are more predictable.
• Better dynamic performance due to higher magnetic flux density in the air gap.
• Simplified construction and essentially maintenance-free.
• More compact size.
• Less bearing current due to a large air gap.
• Low temperature due to less rotor losses.
• Ramp-up time is shorter, constant power up to maximum speed.
