Abstract: Transverse flux permanent magnet machine (TFPM) is well
known for its achievable high torque density and flexible topologies, which
makes it especially suitable for wind power generation, electric vehicle and
direct drive area. Existing TFPM topologies, however, are subject to high
flux leakage and cogging torque. This paper deals with the design and
optimization of a three phase surface mounted transverse flux permanent
machine (SM-TFPM) to reduce flux leakage and cogging torque, the solutions
of adjusting the interval between magnets and inserting auxiliary stator are
suggested to realize the restriction of both flux leakage and cogging
torque. The finite element analysis (FEA) results show the obvious effects,
and the FEA design is validated via prototype experiment by using
TMS320F28335 based controller and induction machine load. Based on the
abovementioned researches, a further multi-objective optimization is applied
by using differential evolution (DE) algorithm and the optimization results
are compared with the previous design to demonstrate the improved
performance
