Magnetic flux analysis of E-Core hybrid excitation flux switching motor with various topologies

In this paper, magnetic flux analysis of E-Core hybrid excitation flux switching motor (HEFSM) with various slot-pole combinations are presented. With several advantages of concentrated armature and DC field excitation coil (DC-FEC) windings, variable flux capability and robust rotor structure, design feasibility and performances analysis of 6Slot-4Pole, 6Slot-5Pole, 6Slot-7Pole and 6Slot-8Pole E-Core HEFSMs such as flux lines, flux linkage, cogging torque and flux distribution are analyzed based on 2D Finite Element Analysis (2D-FEA). Further design improvements and optimizations will be performed in future to increase their performances in term of torque and power.
