BOBINOX: Reduction of the magnetic induction harmonics, vibrations and noise of an electrical motor

The auxiliary winding is placed in the slots

• The auxiliary winding is connected to capacitors with adequate values
• Induction air gap is more sinusoidal
• Reduction of induction harmonics
• Motor duration increased

Benefits:

• The system is simple, passive, without electronics.
• No adjustment required and helps combat a wide range of frequencies.
• Self-adjustments in case of speed or load change.
• The capacitors box is compact and easy to integrate.
• The benefits are stable :
      - Noise reduction : up to -10dB
      - Vibration reduction : up to -70%
