Abstract:
Hybrid Switched Reluctance Motor (HSRM) has
the advantage of improved torque and efficiency than
conventional Switched Reluctance Motor (SRM). The
presence of permanent magnet and auxiliary winding in
the stator yoke increases the torque density in HSRM
when compared to SRM. However cogging torque and
torque ripple is a major drawback in HSRM which causes
acoustic noise and vibration. This work emphasis on
minimization of torque ripple and cogging torque by
altering the stator and rotor pole geometry. This paper
deals with the influence of altered pole shapes such as
pole tapering in stator, pole shoe attached to rotor and
non-uniform air gap at stator pole face on the torque
characteristics of the HSRM.. Based on the analysis an
optimum design is arrived to enhance the performance of
HSRM.
