Minimization of Cogging Torque for V-Type IPMSM by the Asymmetric Auxiliary Slots on the Rotor
IEEE Access, 2022 The interaction between the permanent magnets and the armature teeth of the PMSM generates cogging torque. It causes vibration and noise. Therefore, this paper establishes the analytical formula of the cogging torque of the motor with auxiliary slots on ...

A novel cogging torque measurement method for multi slot/pole permanent magnet motor
IET Electric Power Applications, 2023 The adverse effect on speed ripple and vibration makes it necessary to evaluate the cogging torque. Due to the tolerance of stator and rotor stacks as well as nonuniform magnetization of permanent magnet, the amplitude of cogging torque is unequal in ...

Cogging torque in slotless permanent magnet machines [PDF]
Journal of Electrical Engineering, 2020 Abstract Slotless permanent magnet machines theoretically do not produce any cogging torque, provided the stator inner surface reluctance remains unchanged. However, a cogging torque may occur due to a change in the electromagnetic design following material cost reduction in the manufacturing process.

A Reduction Method of Cogging Torque for Magnetic Gears [PDF]
Iranian Journal of Electrical and Electronic Engineering, 2023 Nowadays, magnetic gears (MGs) have become an alternative choice for mechanical gears because of their low maintenance, improved durability, indirect contact between inner and outer rotors, no lubrication, and high efficiency.

Cogging Torque Mitigation of Modular Permanent Magnet Machines [PDF]
IEEE Transactions on Magnetics, 2016 This paper proposes a novel cogging torque mitigation method for modular permanent magnet (PM) machines with flux gaps in alternate stator teeth. The slot openings of the modular PM machines are divided into two groups in a special way. By shifting the slot openings of two groups in opposite directions with the same angle, the machine cogging torque ...
