Features
- Precise Winding
The winding of hybrid permanent magnet motor of Sierra oil-free air compressor is directly wound on the convex structure simply and reliably to eliminate low efficiency &heat concentration (oen leading to motor insulation layer destruction and other faults) of ordinary induction motor. While repairing a conventional air compressor may result in shutdown for days or weeks and certain rental cost, and rewinding coils or replacing bearings will cost a lot of manpower and material resources, Sierra stators can be replaced quickly and costs less than replacing motor windings.
- Newly upgraded hybrid permanent magnet motor with no bearings or wear parts
While starting the motor of a conventional air compressor may consume a lot of energy with the starting current usually being up to 8 times of the normal operating current at full load, the hybrid permanent magnet motor of Sierra guarantees that the starting current is less than 100% of the load current, and thus eliminates the impact of air compressor start on the grid and saves energy.
Sierra requires no unloading, but simply lowers the screw speed to accommodate any changes in displacement. Sierra adopts a shutdown mode simpler than the unloading mode of other air compressors. Also, Ingersoll Rand's unique super coating and hybrid permanent magnet motor makes Sierra oil-free screw air compressor to be reliable, and save at least 30% energy over the conventional oil-free screw air compressors.
