Abstract: In this paper, an investigative study on the effect of
various notch depths and notch location angles in the U-core stator
permanent magnet motors is presented, which aims to obtain the proper design
combination of notch parameters for the better motor performance. Finite
element method is carried out for the motor performance evaluation such as
the starting torque, cogging torque as well as the phase back-EMF. The
results show that there are certain ranges of the notch depth and the notch
location angle to generate the larger back-EMF and starting torque with less
cogging torque. Finally, the Simulink models are built and the prototypes
are tested for their dynamic performance comparison.
