Permanent magnet synchronous machines with
fractional-slot non-overlapping windings (FSPMSM), also known
as tooth-coil winding permanent magnet synchronous machines
(TCW PMSM), have been under intensive research during the
latest decade. There are many optimization routines explained
and implemented in the literature in order to improve the
characteristics of this machine type.
This paper introduces a new technique for torque ripple
minimization in TCW PMSM. The source of torque harmonics is
also described. The low order torque harmonics can be harmful
for a variety of applications, such as direct drive wind generators,
direct drive light vehicle electrical motors, and for some high
precision servo applications.
The reduction of the torque ripple harmonics with the lowest
orders (6th and 12th) is realized by machine geometry optimization
technique using finite element analysis (FEA). The presented
optimization technique includes the stator geometry adjustment
in TCW PMSMs with rotor surface permanent magnets and with
rotor embedded permanent magnets. Influence of the permanent
magnet skewing on the torque ripple reduction and cogging
torque elimination was also investigated. It was implemented
separately and together with the stator optimization technique.
As a result, the reduction of some torque ripple harmonics was
attained.
