GCD. Open circuit analysis of concentrated winding in interior permanent magnet machines with fractional slot distribution Abstract: The application of concentrated windings in interior permanent magnet (IPM) machines has been claimed to enhance high-speed performance increasing flux- weakening capabilities of the machine. fractional-slot concentrated-wound (FSCW) motors. This concept has been widely investigated for surface-mounted permanent magnet (SMPM) machines. This thesis studies the same concept applied for synchronous reluctance machines (SynRM). In this thesis, a FSCW, 15 kW, 4-pole, Permanent-Magnet-Assisted Synchronous Reluctance Permanent magnet synchronous machines with fractional slot and with fractional slot and concentrated winding configuration have been steadily gaining The impact of magnet segmentation on magnet eddy current losses in the which would ensure the rotor integrity at expected high rotational speed.
