Original Kurzfassung:
Switched reluctance motors (SRMs) have attracted
considerable attention for energy conversion within industrial
applications. To realize the high-quality operation status,
optimization for SRMs is one of the most essential steps in the
design stage. In this paper, a multi-objective design optimization
method is proposed for a novel SRM with unequal alternating
stator yoke segments. First, the asymmetric flux distribution and
the inconsistent current phenomenon of the conventional six-phase
SRM are introduced. The unequal yoke SRM (UYSRM) is
developed to improve the current profiles and reduce the
unnecessary stator mass. Then, an optimization method
considering the slot fill factor is proposed and performed on the
proposed UYSRM. In the optimization process, the sensitivity
analysis is conducted based on the orthogonal array, and the
sensitive degrees of different variables are calculated. To take full
advantage of the stator slot area, the number of parallel strands of
phase windings is adjusted according to the number of turns and
the variables of the stator. The performances of the UYSRM are
evaluated to validate the proposed SRM and optimization method.
Finally, a prototype motor is manufactured and tested. Both the
simulation and test results verify the effectiveness and
reasonability of the proposed design optimization method for the
UYSRM. Besides, the proposed method offers a new research
orientation for electric machines.
