Application of EM303B screw air compressor
Permanent magnet synchronous motor air compressor control scheme:
①.The rotor magnetic field generated by permanent magnets, no-load current close to zero, the motor loss is small, more than 95% efficiency.
②.Power density, small size, direct drive can reduce mechanical losses, wide load range to maintain high power factor (close to 1), improve power utilization efficiency.
③.effective use of reluctance torque, fast response, permanent magnet synchronous air compressor can achieve an energy efficiency standards.
