[Objective] To address the issue of high-amplitude and low-order harmonics in the magnetomotive force of fractional slot concentrated winding (FSCW) induction motors, this paper proposes three different harmonic suppression schemes: dual Y-shaped winding, star-delta winding, and specific subharmonic suppression winding, aiming to suppress non-dominant pole harmonics. [Method] First, the basic principles of the three harmonic suppression schemes and the distribution patterns of magnetomotive force harmonics under different pole-slot combinations were analyzed. Second, the relationship between the winding distribution factor for each harmonic and the number of turns in different schemes was derived. Then, the theoretical calculation of the suppression effects on the magnetomotive force of various harmonics under different harmonic suppression schemes was carried out. Finally, a 2D finite element model of the FSCW induction motor was established, and the electromagnetic characteristics of the motor under differe
