“…The electromagnetic noise is generated by the radial electromagnetic force harmonics in the air gap exciting the stator and the rotor. In order to reduce the electromagnetic noise in electrical machines, many researchers have proposed several methods, which can be classified into two categories: Passive noise reduction methods, which include Slot numbers combination [ 10 , 11 ]; Machine geometry design [ 12 , 13 , 14 ]; Machine PWM strategy [ 15 , 16 , 17 , 18 ]; Passive anti-harmonic filter [ 19 , 20 , 21 ]; and Active noise reduction methods, which include Piezoelectric actuator [ 22 ]; Injection of current harmonics [ 23 , 24 ]; Injection of current harmonics in auxiliary windings [ 25 ]; Active filter topology [ 26 , 27 ]; …”

In this paper, a passive method for the noise reduction of the PMSM (Permanent Magnet Synchronous Machine) is presented. The principle is to add an auxiliary three-phase winding into the same slots as the initial stator winding, short-circuited via three capacitors of suitable values. The aim is to create a damping effect for flux density harmonic components, especially high-frequency harmonics from the PWM (PulseWidth Modulation), in the air gap in order to reduce the noise and vibration of the PMSM. The method can significantly reduce the global sound pressure level and vibrations for specific frequencies. Because of passive features, the additional winding effectively mitigates magnetic noise without greatly increasing the complexity of design and manufacturing, which also extends its applicability to different PMSMs.
