REVIEW ON MODELLING AND ANALYSIS OF VARIABLE FLUX MACHINES FOR TRACTION APPLICATION

Recently VFMM (Variable Flux Memory Machines) have been gaining popularity for their applications in EV's. These motors have the ability to operate at high speeds while also providing high starting torque. They use non-rare earth LCF magnets which makes the design a potential low cost option in future. This review paper discusses the recent research in VFMM. The first part of review is focused on the types of VFM machines under research. Second part of the paper discusses the latest control methods for VFM machines
