Optimization and analysis of interior permanent magnet drive motor with unequal thickness magnetic poles for electric vehicle [PDF]

Journal of Hebei University of Science and Technology
To enhance the output torque of permanent magnet drive motors for electric vehicles, while simultaneously reducing cogging torque and torque ripple, an interior permanent magnet motor with auxiliary slots in unequal thickness magnetic poles was proposed.
