Permanent Magnet Synchronous Motor (PMSM) for Compressors & Industrial Air Handling​

Working Principle of Permanent Magnet Synchronous Motor (PMSM)

Jasung Permanent Magnet Synchronous Motor (PMSM) 

High Efficiency & Energy Savings​​

Eliminated Slip Losses​​

◇ No slip-induced losses (zero rotor iron/copper losses at fundamental frequency)

Permanent Magnet Excitation Advantages​​

◇ Unity power factor (up to 1.0) capability

◇ Reduced reactive power consumption

◇ Lower stator current → 15-25% decreased copper losses vs. induction motors

Optimized Magnetic Circuit Design​​

◇ Higher pole arc coefficient than induction motors

◇ Reduced average flux density → 30% lower core losses at rated voltage

Advanced Loss Mitigation​​

◇ Trade-off in stray losses:

◇ Increased by PM field harmonics

◇ Decreased via enlarged air gap design

◇ Net 10-15% lower total losses than premium IE4 induction motors
