There were two main drawbacks in the hybrid excited machines: 1) In the first category, because of the reduction in the PM volume and adding the excitation coil to the remaining space, the torque density of the machine decreased. So, the motor with hybrid excitation suffered from extremely low torque for a specified volume/weight. 2) The excitation coil had been placed in the slots where the AC coil had located in the second category. There was an insulation layer between the AC and DC windings to decouple the windings physically. In this strategy, as the space of the AC winding is occupied by the DC winding, the machine’s electrical loading decreases. So, the torque density of the machine was also reduced. We introduce the design and optimization process for electrical machines. Then, a new topology for the HEFSPMM is proposed, which resolves the problems of the traditional case.
