Robust Optimal Design Process for Minimizing the Deviation of Cogging Torque in PMSMs Considering Interaction between Manufacturing Tolerances
2024 IEEE Energy Conversion Congress and Exposition (ECCE)
Year: 2024 | Conference Paper |
Uniformity of performance and minimized maintenance requirements are highly demanded in industrial applications. However, tolerances in the manufacturing process are inevitable, and the inherent manufacturing tolerances degrade the cogging torque performance of permanent magnet synchronous motors (PMSMs). Therefore, a robust optimal design process was proposed to ensure that even if manufacturing ...Show More
Comparative Study of Cogging Torque, Torque Ripple, and Vibration on Stator Tooth Chamfer Types in Permanent Magnet Synchronous Motors
IEEE Transactions on Magnetics
Cited by: Papers (3)
The high power density, high efficiency, and wide speed range of permanent magnet synchronous motors (PMSMs) are attractive features. However, the cogging torque and unsuppressed torque ripple of PMSMs degrade torque quality and reliability and cause vibration. This article compares the effectiveness of PMSMs in reducing the cogging torque, torque ripple, and vibration by applying each stator toot...Show More
Comparative Study of Various Slot Pitch for 2-Pole 6-Slot Ultra-High Speed Permanent Magnet Synchronous Motor
Jae-Hyun Kim;So-Yeon Im;Soo-Min An;Kyoung-Soo Cha;Myung-Seop Lim
2023 IEEE International Magnetic Conference - Short Papers (INTERMAG Short Papers)
Year: 2023 | Conference Paper |
The 2-pole 6-slot permanent magnet synchronous motor (PMSM) is an attractive option for ultra-high-speed (UHS) applications due to their high manufacturability and balanced magnetic force. UHS PMSM should be designed with short stack length and end coil height due to rotor dynamics issue. Also, due to its high frequency, it must be designed considering stator iron loss, rotor eddy current loss, an...Show More
Transfer Learning-Based Design Method for Cogging Torque Reduction in PMSM With Step-Skew Considering 3-D Leakage Flux
Yun-Jae Won;Jae-Hyun Kim;Soo-Hwan Park;Ji-Hyeon Lee;Soo-Min An;Doo-Young Kim;Myung-Seop Lim
IEEE Transactions on Magnetics
Cited by: Papers (7)
Step-skew is a common technique for eliminating the cogging torque of a target harmonic order in permanent magnet synchronous motors (PMSMs). However, when step-skew is applied to the rotor, the cogging torque of the target harmonic order is not completely eliminated due to 3-D leakage flux. Therefore, the 3-D leakage flux should be considered in designing a PMSM with step-skew for cogging torque ...Show More
Comparative Study of Various Slot Pitches for 2-Pole 6-Slot Ultra-high-Speed Permanent Magnet Synchronous Motors

The 2-pole 6-slot (2p6s) permanent magnet synchronous motor (PMSM) is an attractive option for ultra-high-speed (UHS) applications due to its excellent manufacturability and balanced magnetic force. UHS PMSMs should be designed with short stack lengths and end coil heights to address rotor dynamics issues. In addition, given their high frequency, these PMSMs should be designed considering stator i...Show More
