Abstract—This paper presents methods to reduce acoustic noise
in interior permanent magnet (IPM) motor during design stage.
Mechanical and magnetic sources are considered to reduce noise
of the machine, and structural and electromagnetic designs are
performed. In the structural design stage to reduce mechanical
source, the structural resonances are moved to higher frequency
for enhancement of stiffness. Then, the electromagnetic design
stage to reduce magnetic source, the amplitudes of magnetic force
harmonic and torque ripple are reduced by using an optimal
design method, respectively. Two models are designed according
to each objective function, and the validity of the design process
and objective functions is confirmed with their simulated and
experimental results.
