The desired high energy conversion efficiencies over a complete operating torque and speed range combined with the recent increase in cost of rare-earth magnets have brought forth a renewed interest in the induction machine (IM) as a possible alternative to the rare-earth permanent magnet (PM) machine. Fractional-slot concentrated windings (FSCWs) allow significant cost reduction of a machine by reducing copper volume and manufacturing time. However, this type of winding is generally discussed in the context of brushless PM machines. The higher harmonic content of FSCWs is generally understood to be a significant drawback for such designs. We aim to substantiate this understanding by comparing the performances of a baseline IM with a conventional, distributed winding to machines with FSCWs.
