Abstract
This paper concerns the optimization and comparison
of six different axial-flux permanent magnet (AFPM)
machine topologies for an in-wheel direct drive application.
The objective of the optimization is to reach maximum power
density, which is of essence for an in-wheel motor. The machine
topologies are optimized using the 3D analytical charge model
in combination with a thermal equivalent circuit model for
calculation of the temperature rise and thermal dependency of
the main electromagnetic losses. All investigated AFPM machine
topologies are variations of the internal stator twin external rotor
AFPM machine. The resulting designs are compared based on
their power density, weight, efficiency, and permanent magnet
volume. The distributed winding topology with a quasi-Halbach
magnet arrangement shows the best performance within the
optimization problem.
